Introduction
IntelliPak™ II Rooftops Designed For Today, Tomorrow and Beyond
Built on the legacy ofTrane's industry leading IntelliPak, the IntelliPak II 90 to 162 ton platform is
designed for the future. Expanded features and benefits, controls enhancements and world class
energy efficiencies make the IntelliPak II the right choice for demanding applications today, and
tomorrow.
Trane's rooftop unit control module (UCM), an innovative, modular microprocessor control design,
coordinates the actions of the IntelliPak II rooftop for reliable and efficient operation and allows for
standalone operation of the unit.
Access to the unit controls, via a human interface panel, provides a high degree of control, superior
monitoring capability, and unmatched diagnostic information.
Optionally, for centralized building control on-site, or from a remote location, IntelliPak II can be
configured for direct communication with aTraneTracer™ or a 3rd party building management
system using LonTalk® or BACnet®. With any of these systems, the IntelliPak II operating status
data and control adjustment features can be conveniently monitored from a central location.
TheTrane IntelliPak II has the technology and flexibility to bring total comfort to every building
space.

Microchannel Condenser Coils
Microchannel coils are an all aluminum coil that has
been successfully used in the automotive industry for
many years, and is now being applied in the HVAC
industry.The coils have a fully-brazed construction
which increases coil rigidity making them more
rugged to withstand the rigors of jobsite handling.
Additionally, the light weight simplifies coil handling.
The all aluminum construction creates an exceptional
heat transfer capability, allowing the refrigerant
charge to be reduced to levels that exceed LEED EACredit 4 requirements. Bottom line, less refrigerant is
being used, which creates a healthier and greener
environment.

Energy Savings, Improved IAQ and Comfort
IntelliPak II offers several ways to save energy while improving indoor air quality (IAQ) and zone
comfort. Standard factory installed options for energy savings include the energy recovery wheel,
hot gas reheat, and evaporative condensers.

Single Zone VAV (SZVAV)
Single Zone VAV (SZVAV) is designed for use in single zone applications such as gymnasiums,
auditoriums, manufacturing facilities, retail box stores, and any large open spaces where there is
a diversity in the load profile. It is an ideal replacement to "yesterday's" constant-volume (CV)
systems, as it reduces operating costs while improving occupant comfort.
SZVAV systems combineTrane application, control and system integration knowledge to exactly
match fan speed with cooling and heating loads, regardless of the operating condition.Trane
algorithms meet and/or exceed ASHRAE 90.1- 2010 SZVAV energy-saving recommendations and
those of CATitle 24.The result is an optimized balance between zone temperature control and
system energy savings. Depending on your specific application, energy savings can be as much
as 20+%.
Note: Building system modeling in energy simulation software such asTRACE is recommended
to evaluate performance improvements for your application.
SZVAV is fully integrated into the IntelliPak Control system. It provides the simplest and fastest
commissioning in the industry through proven factory-installed, wired, and tested system
controllers. All control modules, logic boards and sensors are factory installed and tested to ensure
the highest quality and most reliable system available.This means no special programming of
algorithms, or hunting at the jobsite for field installed sensors, boards, etc. Single zone VAV is a
quick and simple solution for many applications and is available from your most trusted rooftop
VAV system solution provider -Trane.

Ultra Low Leak, AMCA 1A Economizer Damper
The pre-engineered design special Ultra Low Leak AMCA 1A Economizer Damper package will
meet or exceed requirements of CaliforniaTitle 24, ASHRAE 90.1, and IECC.The economizer,
including linkages and actuators, will have a 5 year limited warranty and functional life of 60,000
opening and closed cycles.
Dampers are AMCA 511 Class 1A certified with a maximum leakage rate of 3 CFM/sq-ft at 1.0 in.WC
pressure differential. As part of this design special package, Fault Detection and Diagnostics (FDD)
control is included to meet California requirements. FDD control monitors the commanded
position of the economizer compared to the feedback position of the damper. If the damper position
is outside of ±10% of the commanded position, a diagnostic is generated.

Features & Benefits

Energy Recovery Wheel
Because the energy recovery wheel has the capability to hold and transfer sensible and latent
energy, this option can significantly reduce HVAC system operating energy costs. IntelliPak II offers
the total energy wheel option to recover energy from the building exhaust. Benefits of the total
energy recovery feature include:
•

Energy efficient ventilation to reduce operating costs

•

The ability to increase ventilation, allowing for improved indoor air quality (IAQ)

•

High efficiency, which permits increased outdoor air quantity without increasing heating or
cooling

Hot Gas Reheat
By its very nature, the colder the air, the less moisture it contains. With hot gas reheat, the cold air
that passes through the DX coil is reheated to an acceptable temperature and returned as
dehumidified air to the facility space.The result is both temperature and humidity are maintained
while reducing unit operating costs and saving energy.
This energy efficiency helps to meet local energy codes and ASHRAE Standard 90.1 compliance.

Evaporative Condensing Units
Unlike air-cooled condensers, evaporative condensers are dependent on the ambient wet bulb,
rather than dry bulb, temperature. Wet bulb temperature is generally several degrees lower than
dry bulb.
Utilizing the lower wet bulb temperature to condense refrigerant vapor can dramatically decrease
compressor power consumption by reducing compressor discharge pressure, thereby increasing
unit efficiency.

Interoperability with LCI and BCI
Integrated Comfort with LonTalk Communication
TraneTracer LonTalk Control Interface (LCI) for IntelliPak II offers a building automation control
system with outstanding interoperability benefits.
LonTalk, which is an industry standard, is an open, secure and reliable network communication
protocol for controls, created by Echelon Corporation and adopted by the LonMark Interoperability
Association. It has been adopted by several standards, such as: EIA-709.1, the Electronic Industries
Alliance (EIA) Control Network Protocol Specification and ANSI/ASHRAE 135, part of the American
Society of Heating, Refrigeration, and Air Conditioning Engineer's BACnet control standard for
buildings.
Interoperability allows application or project engineers to specify the best products of a given type,
rather than one individual supplier's entire system. It reduces product training and installation
costs by standardizing communications across products. Interoperable systems allow building
managers to monitor and control IntelliPak II equipment with aTraneTracer Summit or a 3rd party
building automation system. It enables integration with many different building controls such as
access/intrusion monitoring, lighting, fire and smoke devices, energy management, and a wide
variety of sensors (temperature, pressure, light, humidity, occupancy, CO2 and air velocity). For

Trane Wireless Comm Interface (WCI)
TheTrane Wireless Comm Interface (WCI) is the perfect alternative to BACnet wired
communication links (for example, WCI connection between aTracer SC and aTracer UC400).
Minimizing communication wires between terminal products, zone sensors, and system
controllers has substantial benefits. Installation time and associated risks are reduced. Projects are
completed with fewer disruptions. Future re-configurations, expansions, and upgrades are easier
and more cost effective.

Optimum Building Comfort Control
The modular control design of the UCM allows for greater application flexibility. Customers can
order exactly the options required for the job, rather than one large control package. Unit features
are distributed among multiple field replaceable printed circuit boards.TheTrane UCM can be
setup to operate under one of three control applications:
1. Standalone
2. Interface withTraneTracer building management system
3. Interface with a generic (non-Trane) building management system. All setup parameters are
preset from the factory, requiring less start-up time during installation
The unit mounted human interface and the remote human interface panels' functions are identical,
with the exception of the Service mode which is not available on the remote human interface panel.
This common interface feature requires less time for building maintenance personnel to learn to
interact with the unit.
All rooftop control parameters are adjustable and can be setup through the remote human
interface panel such as, but not limited to: system on/off, demand limiting type, night setback
setpoints, and many other setpoints. No potentiometers are required for setpoint adjustment; all
adjustments are done through the remote human interface keypad.
Up to 56 different rooftop diagnostic points can be monitored through the human interfaces such
as: sensor failures, loss of supply airflow, and compressor trip. No special tools are required for
servicing the unit. All diagnostic displays are available in clear English at the remote human
interface and will be held in memory, so that the operator/service person can diagnose the root
cause of failures.

Statitrac Direct Space Building
Pressurization Control

Figure 15. Statitrac

Trane Statitrac control is a highly accurate and
efficient method of maintaining building pressure
control with a large rooftop air conditioner.
Building space pressurization control is achieved with
a 100 percent modulating exhaust system that
features a single forward curved fan, with modulating
discharge dampers that operates only when needed
or a 100% modulating plenum return fan with airfoil
wheel that operates continuously with the supply fan.
Most of the operating hours of the 100 percent modulating exhaust system are at part load,
resulting in energy savings.
Statitrac, with the 100 percent modulating exhaust system, provides comfort and economy for
buildings with large rooftop air conditioning systems. Statitrac, with the 100% modulating plenum
return fan provides comfort and space pressure control in more demanding applications with high
return static pressure, and applications requiring duct returns.
Statitrac control with exhaust fan is simple!The space pressure control turns the exhaust fans on
and off as required and modulates exhaust dampers, or fan speed, to maintain space pressure
within the space pressure deadband. Economizer and return air dampers are modulated based on
ventilation control and economizer cooling request.
The unit mounted human interface panel can be used to:
1. Adjust space pressure setpoint
2. Adjust space pressure deadband
3. Measure and read building static pressure
The modulating exhaust system maintains the desired building pressure, while saving energy and
keeping the building at the right pressure. Proper building pressurization eliminates annoying door
whistling, doors standing open, and odors from other zones.The Statitrac direct space building
control sequence will also be maintained when a variable frequency drive is used.

Statitrac Control with Plenum Return Fan is State of the Art!
Other manufacturers utilize a fan tracking control scheme whereby the return fan speed tracks the
supply fan speed in a linear fashion.This scheme works well at minimum and maximum CFM
airflow. However, due to the dissimilar performance characteristics of the supply and return fan,
building pressure is difficult to control at points between minimum and maximum CFM airflow.
TheTrane return fan/building pressurization control system eliminates the effects of dissimilar
supply/return fan characteristics experienced in a linear tracking control system by modulating the
exhaust dampers based on space pressure, the return/economizer dampers based on ventilation
requirements, and the return fan speed based on return plenum static pressure.The supply fan,
return fan, exhaust damper, and return/economizer damper systems act independently from one
another to maintain comfort and building pressure.
The return fan operates whenever the supply fan is in operation.The unit exhaust dampers are
modulated in response to the space pressure signal to maintain space pressure within the space
pressure deadband.The unit economizer and return air dampers are modulated based on
ventilation control, minimum outside air economizer position, and economizer cooling request.
The return fan speed is modulated based on a return duct static pressure deadband control. Using
the unit mounted Human Interface, the operator can:
1. Adjust space pressure setpoint
2. Adjust space pressure deadband

Variable Frequency Drives (VFD)
Variable Frequency Drives are factory installed and tested to provide supply/exhaust/return fan
motor speed modulation. VFD's, as compared to discharge dampers, are quieter, more efficient,
and may be eligible for utility rebates.The VFD's are available with or without a bypass option.
Bypass control will simply provide full nominal airflow in the event of drive failure.

Rapid Restart
Trane understands that every second counts.Trane equipment, controls, and control sequences
are designed to get the system back online and properly functioning should the facility experience
a power cycle event.
•

Trane HVAC system design is optimized for fast restart.

•

IntelliPak Rooftop System controls and equipment provide an integrated, pre-engineered
solution for fast restart.

•

Proven operational procedures maximize uptime outside of critical outages and get the system
up and running as quickly as possible.

With Rapid Restart and use of a backup generator, the IntelliPak Rooftop System can provide full
cooling in 120 seconds or less after regaining electrical power.This option is fully integrated into
the IntelliPak controls logic via standard human interface. Rapid Restart is a perfect fit in timesensitive applications where extended down time is not an option and heating/cooling is crucial.

Note: When noted in this sequence “human interface panel,” the reference is to both the unit
mounted and remote mounted human interface panel. All setpoint adjustments can be
accomplished at the unit or remote human interface panel.

Supply Air Pressure Control
Variable Frequency Drive (VFD) Control
Variable frequency drives are driven by a modulating 0-10 VDC signal from the Rooftop Module
(RTM). A pressure transducer measures duct static pressure, and theVFD is modulated to maintain
the supply air static pressure within an adjustable user-defined range.The range is determined by
the supply air pressure setpoint and supply air pressure deadband, which are set through the
human interface panel or BAS/Network.
Variable frequency drives provide supply fan motor speed modulation.The drive will accelerate or
decelerate as required to maintain the supply static pressure setpoint. When subjected to high
ambient return conditions the VFD will reduce its output frequency to maintain operation. Bypass
control is offered to provide full nominal airflow in the event of drive failure.

Supply Air Static Pressure Limit
The opening of VAV terminals, and the amount of supply air provided by the variable frequency
drive are coordinated during start up and transition to/from Occupied/Unoccupied modes to
prevent over pressurization of the supply air ductwork. However, if for any reason the supply air
pressure exceeds the user-defined supply air static pressure limit that was set at the human
interface panel, the supply fan and VFD are shut down.The unit is then allowed to restart three
times. If the over pressurization condition occurs on the third time, the unit is shut down and a
manual reset diagnostic is set and displayed at the human interface panel and BAS/network.

Supply Air Temperature Controls
Cooling/Economizer
During Occupied cooling mode of operation, the economizer (if available) and mechanical cooling
are used to control the supply air temperature.The supply air temperature setpoint and deadband
are user-defined at the human interface panel.The supply air temperature setpoint may be userdefined from the BAS/network. If the conditions of the outside air are appropriate to use “free
cooling,” the economizer will first be used in an attempt to satisfy the supply air setpoint; then, if

required, the mechanical cooling will be staged on to maintain supply air temperature setpoint.
Minimum On/Off timing of the mechanical cooling prevents rapid cycling.
On units with economizer, a call for cooling will modulate the outside air dampers open.The rate
of economizer modulation is based on deviation of the supply air temperature from setpoint, i.e.,
the further away from setpoint, the faster the outside air damper will open. First stage of cooling
will be allowed to start after the economizer reaches full open.
Note: The economizer is only allowed to function freely if one of the following conditions is met.
For dry bulb economizer control the ambient temperature must be below the dry bulb
temperature control setting. For reference enthalpy economizer control, outdoor air
enthalpy must be below the enthalpy control setting. At outdoor air conditions above the
enthalpy control setting, mechanical cooling only is used and the outside air dampers
remain at minimum position. For comparative enthalpy economizer control, outdoor air
enthalpy must be below the enthalpy of the return air.
If the unit does not include an economizer, mechanical cooling only is used to satisfy cooling
requirements.The outdoor air dampers may be set for a maximum of 25% outdoor air, through the
unit mounted human interface panel or a signal from the BAS/network, if the rooftop is equipped
with 0 to 25% motorized outside air dampers.

Heating
Modulating Gas
Upon a call for heating, the HEAT module closes the heating contacts, beginning the firing
sequence. First, the heat exchanger combustion blower begins operation. Upon positive proving
of combustion airflow, a 60 second pre-purge cycle is executed.Then the ignition sequence takes
place.
If ignition is not proven, the safety control locks out and must be manually reset. As long as there
is a call for heat, the safety control can be reset, which starts another purge cycle and try for ignition.
Once ignited, as additional heat is required, the combustion air damper opens, increasing the firing
rate.
During heating operation, an electronic flame safety control provides continuous flame
supervision. If combustion should become unstable for any reason, heating will automatically shut
down and be locked out until reset at the unit mounted Human Interface panel.
As the heating requirement is satisfied, the HEAT module will modulate the combustion air damper
closed and the firing rate will lower to maintain the desired outlet temperature. When the
requirement is fully satisfied, the heating contacts are opened, de-energizing the heat.The specific
sequence of operation of the gas heat will depend on the size of the heat exchanger.

Electric Heating
The individual stages of electric heat will be sequenced on the zone demand.The number of
available stages will depend on the unit size and heat capacity selected.

Hot Water or Steam
On units with hot water or steam heating, the supply air temperature can be controlled to a heating
setpoint during the Occupied mode.The supply air temperature heating setpoint and deadband are
user-defined at the Human Interface Panel. VAV Occupied heating on hot water and steam heat
units is enabled by closing a field-supplied switch or On units with hot water or steam heating, the

Figure 17. Supply air temperature reset

Supply Air Setpoint Reset
Supply air setpoint reset can be used to adjust the supply air temperature setpoint on the basis of
a zone temperature or on outdoor air temperature. Supply air setpoint reset adjustment is available
from the Human Interface Panel for supply air heating and supply air cooling control.
Outdoor air cooling reset is sometimes used in applications where the outdoor temperature has
a large effect on building load. When the outside air temperature is low and the building cooling
load is low, the supply air setpoint can be raised, thereby preventing subcooling of critical zones.
This reset can lower usage of mechanical cooling, thus savings in compressor kW, but an increase
in supply fan kW may occur.
Outdoor air heating reset is the inverse of cooling, with the same principles applied.
For both outdoor air cooling reset and heating reset, there are three user-defined parameters that
are adjustable through the Human Interface Panel:
– Beginning reset temperature
– Ending reset temperature
– Amount of temperature reset
Zone reset is applied to the zone(s) in a building that tend to over cool or overheat.The supply air
temperature setpoint is adjusted based on the temperature of the critical zone(s).This can have the
effect of improving comfort and/or lowering energy usage.The user-defined parameters are the
same as for outdoor air reset. See Figure 16, p. 16

Supply Air Tempering
Modulating gas, electric, hot water and steam heat units only—when supply air temperature falls
below the supply air temperature deadband low end, the heat valve is modulated open to maintain
the set minimum supply air temperature.

Zone Temperature Control
Unoccupied Zone Heating and Cooling
During Unoccupied mode, the unit is operated as a CV unit. VFDs operate at 100% and VAV boxes
are driven full open.The unit controls zone temperature within the Unoccupied zone cooling and
heating (heating units only) setpoints.

Daytime warm-up
This feature is available on all types of heating units. During Occupied mode, if the zone
temperature falls to a preset, user-defined zone low limit temperature setpoint, the unit is put into
Unoccupied mode and Daytime Warm-up is initiated.The system changes over to CV heating (full
unit airflow), theVAV boxes are fully opened and full heating capacity is provided until the Daytime
Warm-up setpoint is reached.The unit is then returned to normal Occupied mode.

Outside Air Measurement
Trane air quality (Traq) outside air measurement damper system utilizes velocity pressure sensing
rings. Based on unit design CFM, the ventilation control module (VCM) monitors and controls the
quantity of outside air entering the unit.The outside airflow can be calibrated to accommodate for
altitude.
a. An optional temperature sensor may be connected to the ventilation control module to
enable it to control a field-installed pre-heater.
b. An optional CO2 sensor may be connected to the ventilation control module to control
outside air based on CO2 Demand Control Ventilation (DCV).

Outside Air CFM Compensation
As the supply fan modulates, this function proportionally adjusts the economizer minimum
position to compensate for the change in total airflow, in order to maintain a constant percent of
outside air.The modified economizer minimum position is computed as a linear function, based
on VFD position, given the two endpoints,
a. Minimum Position with VFD @ 0%
b. Minimum Position with VFD @ 100%
Both are user adjustable at the Human Interface Panel.

Single Zone Variable Air Volume (SZVAV) Only
The IntelliPak controls platform will support Single Zone VAV as an optional unit control type in
order to meet ASHRAE 90.1.The basic control will be a hybridVAV/CV configured unit that provides
discharge temperature control to a varying discharge air temperature target setpoint based on the
space temperature and/or humidity conditions. Concurrently, the unit will control and optimize the
supply fan speed to maintain the zone temperature to a zone temperature setpoint.

Supply Fan Output Control
Units configured for Single ZoneVAV control will utilize the same supply fan output control scheme
as on traditionalVAV units except theVFD signal will be based on zone heating and cooling demand
instead of the supply air pressure.

VFD Control
Single Zone VAV units will be equipped with a VFD-controlled supply fan which will be controlled
via a 0-10 VDC signal from the Rooftop Module (RTM). With the RTM supply fan output energized
and the RTM VFD output at 0 VDC, the fan speed output is 37% (22Hz) from the VFD by default; and
at 10 VDC the fan speed output is 100% (60Hz).The control scales the 0-10 VDC VFD output from
the RTM linearly to control between the 37-100% range.The VFD will modulate the supply fan
motor speed, accelerating or decelerating as required to maintain the zone temperature to the zone
temperature setpoint. When subjected to high ambient return conditions the VFD will reduce its
output frequency to maintain operation. Bypass control is offered to provide full nominal airflow
in the event of drive failure.

Units configured for Single Zone VAV control will require special handling of the OA Damper
Minimum Position control in order to compensate for the non-linearity of airflow associated with
the variable supply fan speed and damper combinations. Units configured forTRAQ with or
without DCV will operate identically to traditional units with no control changes.

Space Pressure Control
For units configured with Space Pressure Control with or without Statitrac, the new schemes
implemented for economizer minimum position handling require changes to the existing Space
Pressure Control scheme in order to prevent over/under pressurization.The overall scheme will
remain very similar to VAV units with Space Pressure Control with the exception of the dynamic
Exhaust Enable Setpoint.
For SZVAV an Exhaust Enable Setpoint must be selected during the 100% Fan Speed Command.
Once selected, the difference between the Exhaust Enable Setpoint and Design OA Damper
Minimum Position at 100% Fan Speed Command will be calculated.The difference calculated will
be used as an offset and added to the Active Building Design OA Minimum PositionTarget in order
to calculate the dynamic Exhaust EnableTarget, which will be used throughout the Supply Fan
Speed/OA Damper Position range.
The Exhaust EnableTarget could be above or below the Active Building Design OA Minimum
PositionTarget Setpoint, based on the Active Exhaust Enable Setpoint being set above or below
the Building Design Minimum Position at 100% Fan Speed Command. Note that an Exhaust Enable
Setpoint of 0% will result in the same effect on Exhaust Fan control as onVAV applications with and
without Statitrac.

Occupied Cooling Operation
For normal cooling operation, cooling capacity will be staged or modulated in order to meet the
calculated discharge air target setpoint. If the current active cooling capacity is controlling the
discharge air within the deadband, no additional cooling capacity change will be requested. As the
Discharge AirTemperature rises above the deadband, the algorithm will request additional
capacity as required (additional compressors or economizer). As the Discharge AirTemperature
falls below the deadband, the algorithm will request a reduction in active capacity.

Default Economizer Operation
By default, the unit will be setup to optimize the minimum supply fan speed capability during
Economizer Only operation. If the economizer is able to meet the demand alone, due to desirable
ambient conditions, the supply fan speed will be allowed to increase above the minimum prior to
utilizing mechanical cooling if discharge air setpoint falls below the discharge air Lower Limit
(Cooling) setpoint.

Unoccupied Mode
In Unoccupied periods the unit will utilize setback setpoints, 0% Minimum OA Damper position, and
Auto Fan Mode operation as on normal ConstantVolume units.The Supply Fan speed will be forced
to 100% for all active heating and cooling requests in this mode.

Occupied Heating Operation
Occupied heating operation will utilize two separate control methodologies based on heating
configurations. For all “Staged” Heating types, the unit will utilize full airflow during all active
heating periods exactly like traditional ConstantVolume units. For “Modulating” Heating types the
unit will have the ability to utilize SZVAV Heating, much like Active Cooling, in order to maintain
the ZoneTemperature to the Zone Heating setpoint. Also, on units configured with a Modulating
Heat type, the customer will have the ability to select between the new SZVAV Heating control, or
to utilize traditional Constant Volume, full airflow heating based on the associated unit setup.

Compressor (DX) Cooling
Compressor control and protection schemes will function identical to that of a traditional unit.
Normal compressor proving and disable input monitoring will remain in effect as well as normal
3-minute minimum on, off, and inter-stage timers. Also, all existing head pressure control schemes
will be in effect.

Cooling Sequence
If the control determines that there is a need for active cooling capacity in order to meet the
calculated discharge air target setpoint, once supply fan proving has been made, the unit will begin
to stage compressors accordingly. Note that the compressor staging order will be based on unit
configuration and compressor lead/lag status.
Once the discharge air target setpoint calculation has reached the Minimum Setpoint and
compressors are being utilized to meet the demand, as the discharge air target setpoint value
continues to calculate lower the algorithm will begin to ramp the supply fan speed up toward 100%.
Note that the supply fan speed will remain at the compressor stage’s associated minimum value
(as described below) until the discharge air target setpoint value is calculated below the discharge
air temperature Minimum Setpoint (limited discharge air target setpoint).
As the cooling load in the zone decreases the zone cooling algorithm will reduce the speed of the
fan down to minimum per compressor stage and control the compressors accordingly. As the
compressors begin to de-energize, the supply fan speed will fall back to the Cooling Stage’s
associated minimum fan speed, but not below. As the load in the zone continues to drop, cooling
capacity will be reduced in order to maintain the discharge air within the ±½ discharge air target
deadband.

Constant Volume (CV) Only
Occupied Zone Temperature Control
Cooling/Economizer
During Occupied cooling mode, the economizer (if provided) and mechanical cooling are used to
control zone temperature.The zone temperature cooling setpoint is user-defined at the Human
Interface Panel or from the BAS/Network. If the conditions of outside air is appropriate to use “free
cooling”, the economizer will be used first to attempt to satisfy the cooling zone temperature
setpoint; then the compressors will be staged up as necessary. Minimum on/off timing of
compressors prevents rapid cycling.
On units with economizer, a call for cooling will modulate the outside air dampers open.The rate
of economizer modulation is based on deviation of the zone temperature from setpoint, i.e., the
further away from setpoint, the faster the outside air damper will open. First stage of cooling will
be allowed to start after the economizer reaches full open.
Note: The economizer is only allowed to function freely if one of the following conditions is met:
For dry bulb economizer control, the ambient temperature must be below the dry bulb
temperature control setting. For reference enthalpy economizer control, outdoor air
enthalpy must be below the enthalpy control setting. At outdoor air conditions above the
enthalpy control setting, mechanical cooling only is used and the outdoor air dampers
remain at minimum position. For comparative enthalpy economizer control, outdoor air
enthalpy must be below the enthalpy of the return air.
If the unit does not include an economizer, mechanical cooling only is used to satisfy cooling
requirements.
The outdoor air dampers may be set for a maximum of 25% outdoor air, through the unit mounted
Human Interface Panel or a signal from the BAS/network, if the rooftop is equipped with 0 to 25%
motorized outside air dampers.

Heating
Gas Heating: Two-Stage
Upon a call for heating, the HEAT module closes the first stage heating contacts beginning the firing
sequence. First, the heat exchanger combustion blower begins operation. Upon positive proving
of combustion airflow, a 60 second pre-purge cycle is executed.Then the ignition sequence takes
place.
If ignition is not proven, the safety control locks out and must be manually reset. As long as there
is a call for heat, the safety control can be reset, which starts another purge cycle and try for ignition.
As additional heat is required, the HEAT module will close the second stage heating contacts and
depending on heat module size, will open either the second stage of the gas valve, or a second
stage gas valve.
During heating operation, an electronic flame safety control provides continuous flame
supervision. If combustion should become unstable for any reason, heating will automatically shut
down. On the low heat for all unit sizes and the medium heat for the 90 and 105 ton, after a one
minute delay, plus another 60 second pre-purge cycle the ignition cycle begins. On all other heat
sizes the heating section will be shutdown and locked out until manually reset at the ignition
module and unit mounted Human Interface Panel after the first shutdown due to flame instability.
As the heating requirement is satisfied, the HEAT module will open the second stage heating relay,
de-energizing the second stage of heat. When the requirement is fully satisfied, the first stage
contacts are opened, de-energizing the first stage of heat.

Gas Heating: Modulating Gas
Upon a call for heating, the HEAT module closes the heating contacts, beginning the firing
sequence. First, the heat exchanger combustion blower begins operation. Upon positive proving
of combustion airflow, a pre-purge cycle is executed.Then the ignition sequence takes place.
If ignition is not proven, the safety control locks out and must be manually reset. As long as there
is a call for heat, the safety control can be reset, which starts another purge cycle and try for ignition.
Once ignited, as additional heat is required, the combustion air damper opens, increasing the firing
rate. During heating operation, an electronic flame safety control provides continuous flame
supervision. If combustion should become unstable for any reason, heating will automatically shut
down and be blocked out until reset at the unit mounted Human Interface panel.
As the heating requirement is satisfied, the HEAT module will modulate the combustion air damper
closed, and the firing rate will lower to maintain the desired outlet temperature. When the
requirement is fully satisfied, the heating contacts are opened, de-energizing the heat.The specific
sequence of operation of the gas heat will depend on the size of the heat exchanger.

Electric Heating
The individual stages of electric heat will be sequenced on the zone demand.The number of
available stages will depend on the unit size and heat capacity selected.

Hot Water or Steam Heating
Upon a call for heat, the UCM will send a varying voltage signal to the valve actuator.The valve
will modulate to meet building demand as indicated by the voltage signal. When heating is
satisfied, the valve will modulate closed. A temperature sensor is located on the coldest section of
the coil.When it senses an impending freeze condition, a signal is sent to the hydronic valve to drive
it full open. If the supply fan is on, or if the outside air damper is open when this freezing condition
is sensed, the supply fan is turned off and the outside air damper is closed.

Supply Air Tempering
For staged gas and electric heat units in the occupied Heating mode but not actively heating, if the
supply air temperature drops to 10°F below the Occupied zone heating temperature setpoint, one
stage of heat will be brought on to maintain a minimum supply air temperature.The heat stage is

turned off if the supply air temperature rises to 10°F above the Occupied zone heating temperature
setpoint. On units with hot water or steam heating, if the supply air temperature drops below 48°F,
the heating valve is modulated to maintain 50°F supply air temperature with a 4°F deadband.

Auto Changeover
When the System Mode is “Auto,” the mode will change to cooling or heating as necessary to satisfy
the zone cooling and heating setpoints.The zone cooling and heating setpoints can be as close as
2°F apart.

Unoccupied Zone Temperature Control
Cooling and Heating
Cooling and/or heating modes can be selected to maintain Unoccupied zone temperature
setpoints. For Unoccupied periods, heating, economizer operation or compressor operation can be
selectively locked out at the Human Interface Panels.

CV, SZVAV, and VAV
Note: SZVAV exceptions are noted in parenthesis.

Space Pressure Control - Statitrac
A pressure transducer is used to measure and report direct space (building) static pressure.The
user-defined control parameters used in this control scheme are space static pressure setpoint,
space pressure deadband and exhaust enable point. As the economizer opens, the building
pressure rises and once above the exhaust enable point, enables the exhaust fan and dampers or
exhaust VFD.The exhaust dampers or VFD then modulate to maintain space pressure within the
deadband.

Morning Warm-up Options (Not applicable to SZVAV)
This feature may be enabled on all types of factory installed heat units as well as cooling only units
configured as “External Heat” (for example, VAV boxes with reheat). At the conclusion of
Unoccupied mode, while the economizer (if supplied) is kept closed, the selected zone is heated
to the user-defined Morning Warm-up setpoint.The unit is then released to Occupied mode.There
are two types of Morning Warm-up: full capacity or cycling capacity.
1. Full Capacity Morning Warm-up (MWU)
Full capacity Morning Warm-up uses full heating capacity, and heats the zone up as quickly as
possible. Full heating capacity is provided until the MorningWarm-up setpoint is met. At this point,
the unit is released to occupied mode.
2. Cycling Capacity Morning Warm-up (MWU)
Cycling capacity Morning Warm-up provides a more gradual heating of the zone. Normal zone
temperature control with varying capacity is used to raise the zone temperature to the MWU zone
temperature setpoint.This method of warm-up is used to overcome the “building sink” effect.
Cycling capacity MWU will operate until the MWU setpoint is reached or for 60 minutes, then the
unit switches to Occupied mode. A control algorithm is used to increase or decrease the amount
of heat in order to achieve the MWU zone temperature setpoint.
Note: When using the Morning Warm-up option in a VAV heating/cooling rooftop, airflow must
be maintained through the rooftop unit.This can be accomplished by electrically tying the
VAV boxes to the VAV box output relay contacts on the Rooftop Module (RTM) or by using
changeover thermostats. Either of these methods will assure adequate airflow through the
unit and satisfactory heating of the building.

Evaporator Coil Frost Protection - Frostat
A temperature sensor on each evaporator circuit is used to determine if the coil is getting close to
a freezing condition. Mechanical cooling capacity is shed as necessary to prevent icing.

Controls

The Frostat system eliminates the need for hot gas bypass and adds a suction line surface
temperature sensor near theTXV bulb location to shed cooling when coil frosting conditions occur.
The supply fans are not shut off and will de-ice the coil.Timers prevent the compressors from rapid
cycling.

Steam and Hot Water Coil - Freeze Avoidance
Freeze Avoidance is a feature which helps prevent freezing of steam or hot water heat coils during
periods of unit inactivity and low ambient temperatures. Whenever the unit supply fan is off, the
outdoor air temperature is monitored. If the temperature falls below a predetermined value, the
heating valve is opened to a position selected at the unit mounted Human Interface to allow a
minimum amount of steam or hot water to flow through the coil and avoid freezing conditions.

Occupied/Unoccupied Switching
Description - 3 ways to switch Occupied/Unoccupied:
1. Night Setback (NSB) Panel
2. Field-supplied contact closure (hard wired binary input to RTM) (CV, SZVAV & VAV)
3. Tracer (or 3rd Party BAS with LCI or BCI module)

Night Setback Sensors
Trane's night setback sensors are programmable with a time clock function that provides
communication to the rooftop unit through a 2-wire communications link.The desired transition
times are programmed at the night setback sensor and communicated to the rooftop.
Night setback (unoccupied mode) is operated through the time clock provided in the sensors with
night setback. When the time clock switches to night setback operation, the outdoor air dampers
close and heating/cooling can be enabled or disabled depending on setup parameters. As the
building load changes, the night setback sensor energizes the rooftop heating/cooling (if enabled)
function and the evaporator fan.The rooftop unit will cycle through the evening as heating/cooling
(if enabled) is required in the space. When the time clock switches from night setback to occupied
mode, all heating/cooling functions begin normal operation.
When using the night setback options with a VAV heating/cooling rooftop, airflow must be
maintained through the rooftop unit.This can be accomplished by electrically tying the VAV boxes
to the VAV Box output relay contacts on the Rooftop Module (RTM) or by using changeover
thermostats. Either of these methods will assure adequate airflow through the unit and satisfactory
temperature control of the building.

Occupied/Unoccupied input on the RTM
This input accepts a field supplied switch or contacts closure such as a time clock.

Trane Tracer or BAS System
TheTraneTracer System or a 3rd party BAS (with LCI or BCI module) can control the Occupied/
Unoccupied status of the rooftop.

Timed Override Activation - ICS
This function is operational when the RTM is selected as the ZoneTemperature Sensor source at
the Human Interface Panel. When this function is initiated by the push of a override button on the
ICS sensor, theTracer will switch the unit to the Occupied mode. Unit operation (Occupied mode)
during timed override is terminated by a signal fromTracer.

Timed Override Activation - Non-ICS
This function is active whenever the RTM is selected as the ZoneTemperature Sensor source at the
Human Interface Panel.When this function is initiated by the push of an override button on the zone
sensor, the unit will switch to the Occupied mode. Automatic Cancellation of theTimed Override
Mode occurs after three hours of operation.

An optional Comparative Enthalpy system is used to control the operation of the economizer, and
measures the temperature and humidity of both return air and outside air to determine which
source has lower enthalpy.This system allows true comparison of outdoor air and return air
enthalpy by measurement of outdoor air and return air temperatures and humidities.

Reference Enthalpy Control of Economizer
The optional reference enthalpy compares outdoor air temperature and humidity to the
economizer enthalpy control setpoint. If outdoor air temperature and humidity are below the
economizer enthalpy control setpoint, the economizer will operate freely.
This system provides more sophisticated control where outdoor air humidity levels may not be
acceptable for building comfort and indoor air quality.

Dry Bulb Temperature Control of Economizer
The optional dry bulb system measures outdoor temperature comparing it to the economizer
control temperature setpoint. If the outdoor temperature is below the economizer dry bulb
temperature control setpoint, the economizer will operate freely.This system is best suited for arid
regions where the humidity levels of outside air would not be detrimental to building comfort and
indoor air quality.

Refrigeration Circuit Lead/Lag
Refrigeration Circuit lead/lag is a user-selectable feature through the Human Interface Panel
available on all units. After each request for compressor operation, the lead refrigeration circuit
switches, thereby causing a more equitable or balanced run time among compressors.

Emergency Stop Input
A binary input is provided on the Rooftop Module (RTM) for installation of field provided switch or
contacts for immediate shutdown of all unit functions.

Anti-short Recycle Protection
A standard feature provided to prevent excessive cycling, and premature wear, of the compressors,
contactors and related components.

High Duct Temperature Sensor
Two manual reset, high temperature limit thermostats are provided. One is located in the discharge
section of the unit set at 240ºF and the other in the return air section of the unit set at 135ºF. If either
setpoint is reached, the rooftop unit is shut down.

CO2 Control - Demand Control Ventilation (DCV)
A ventilation reset function that provides the necessary ventilation for occupants and reduces
energy consumption by minimizing the outdoor air damper position (or the OA flow setpoint with
TRAQ) below the Building Design Minimum, while still meeting the ASHRAE Std 62.1-2004
ventilation requirements.
If the space CO2 level is greater than or equal to the CO2 Design Setpoint, the outdoor air damper
will open to the Design Min Outdoor Air Damper (or OA Flow) Setpoint. If there is a call for
economizer cooling, the outdoor air damper may be opened further to satisfy the cooling request.
If the space CO2 level is less than or equal to the CO2 Minimum Setpoint, the outdoor air damper
will close to the DCV Minimum Outdoor Air Damper (or OA Flow) Setpoint. If there is a call for
economizer cooling, the outdoor air damper may be opened further to satisfy the cooling request.
If the space CO2 level is greater than the CO2 Minimum Setpoint and less than the CO2 Design
Setpoint, the outdoor air damper position is (or OA flow) modulated proportionally to the Space
CO2 level relative to a point between the CO2 Min Setpoint and the CO2 Design Setpoint. If there

is a call for economizer cooling, the outdoor air damper may be opened further to satisfy the
cooling request. See Figure 19, p. 37.
Note: CO2 sensor used with Demand ControlVentilation must be powered from an external power
source or separate 24 VAC transformer.

Humidification Control
A relay output is provided to control an externally connected, field supplied humidifier. Logic is
provided for Occupied and Unoccupied humidification control with safeguards to prevent cycling
between humidification and dehumidification

Return Fan Control
A return fan reduces the load on the supply fan motor or can allow a unit to operate at a higher static
pressure.The return fan VFD is modulated independently to maintain desired return air plenum
pressure. In all other cases the return fan is turned on or off with the supply fan.

Low Charge Protection
The low charge feature measures the entering and leaving evaporator temperatures on each circuit
to calculate a superheat value for each circuit.The superheat value is used for multiple purposes:
1. Displayed at the Human Interface panel to assist the service technician with unit charging and
diagnostics
2. A diagnostic message displayed at the Human Interface panel, warning of a low charge
situation when the unit is just slightly undercharged.The unit will be allowed to run.
3. A diagnostic message displayed at the Human Interface panel, warning of a low charge
situation when the unit is undercharged.The undercharged circuit will be locked out to protect
the compressors.

Condenser Fan Cycling
The IntelliPak II controller cycles condenser fans based on ambient temperature and saturated
condensing temperature to ensure the optimum operating conditions for the unit.

LonTalk Building Automation System
The LonTalk Communication Interface for IntelliPak II (LCI-I) controller expands communications
from the unit UCM network to aTraneTracer Summit or a 3rd party building automation system,
utilizing LonTalk, and allows external setpoint and configuration adjustment and monitoring of
status and diagnostics.The LCI-I utilizes an FTT-10A free topology transceiver, which supports nonpolarity sensitive, free topology wiring, which allows the system installer to utilize star, bus, and
loop architectures.This controller works in standalone mode, peer-to-peer with one or more other
units, or when connected to aTraneTracer Summit or a 3rd party building automation system that
supports LonTalk.The LCI-I controller is available as a factory or field-installed kit.

BACnet Building Automation System
The BACnet Communication Interface for IntelliPak II (BCI-I) controller expands communications
from the unit UCM network toTracer SC or a 3rd party building automation system, utilizing
BACnet, and allows external setpoint and configuration adjustment and monitoring of status and
diagnostics.The BCI-I utilizes the BACnet defined MS/TP protocol as defined in ASHRAE standard
135-2004.This controller works in standalone mode, withTracer SC or when connected to a 3rd
party building automation system that supports BACnet.The BCI-I controller is available as a
factory or field-installed kit.

Wireless Comm Interface
Trane Wireless Comm replaces the BACnet communication link and sensor wire onTracer building
automation systems for faster, easier, lower-risk installation and life-cycle savings.

Twinning
Twinning is a master unit and one or more similarly configured slave unit(s) operating
cooperatively, to provide higher capacity and/or redundancy at partial capacity.
Twinning requires an LCI module be installed in each unit and is accomplished by binding variables
between unit communication modules, communicating common setpoints and conditions
(temperatures, pressures, fan speeds, damper positions, occupancy, states, etc.), and allowing
each unit to run independent algorithms.
Note: BCI-I does not have twinning capabilities.
Twinned units must share a common supply and return duct network.
Twinned units operate:
a. as part of aTrane Integrated Comfort System installation, withTracer Summit.
b. on an inter-operable project with a 3rd party LonTalk.
c. as an independent group (bound via Rover or 3rd party tool).

Energy Recovery Wheel
Variable effectiveness is a means to control the capacity of an energy wheel. Normal wheel sizing
is for worst case winter/summer load; therefore, at part load the wheel may be oversized and
variable effectiveness is justifiable.
Variable effectiveness control can be used in any application where the outdoor air temperature
may fall between the discharge air setpoint and the temperature at which heating is required.

For example, a job may have a required supply
air set point of 55°F. A typical return air
temperature may be 70°F and the outside air
temperature 40°F.The energy wheel could heat
the supply air to over 60°F, but by employing
variable effectiveness, the energy wheel
capacity can be modulated to exactly match the
required supply air temperature without using
additional heating or cooling.Therefore,
variable effectiveness control can significantly
add to the amount of energy saved in a year.

Figure 20. Variable sensible effectiveness
control

Variable effectiveness can be accomplished by
varying the wheel rotational speed or by
bypassing a portion of the exhaust air around
the wheel matrix. IntelliPak II utilizes an exhaust
air bypass damper for capacity control.
When unit mode and psychrometric conditions
allow, the energy recovery wheel will turn "ON".
The wheel uses energy from the return air
stream to temper the outside air stream,
thereby reducing the load of the space without
utilizing mechanical cooling and heating.

Hot Gas Reheat (Modulating Reheat Dehumidification)
When space conditions allow, the modulating dehumidification function activates the reheat mode
providing dehumidification of the space.
The reheat valve and cooling valve are modulated to control the discharge air temperature to the
discharge air temperature reheat setpoint (default 70F).
In reheat mode, the reheat valve is commanded (5 to 85%) to control to the discharge air reheat
setpoint and the cooling valve mirrors the reheat valve position (85 to 5%).

Low Ambient Function
The low ambient function is a head pressure control scheme to allow compressor operation at
lower ambient temperatures without tripping the low pressure cutout switch (LPC). For this
function, normal condenser fan staging applies.The first condenser fan on each circuit is
modulated by aVFD.The fan speed is modulated to control to the saturated condenser temperature
control Setpoint.

Low Ambient Compressor Lockout
This function will lock out the compressor if the outdoor air temperature is below the low ambient
compressor lock out temperature setpoint.The factory setpoint is 50°F on standard units and 0°F
on low ambient units.This setpoint is adjustable at the Human Interface Panel. Compressors will
be locked out when outdoor air temperatures falls below that selected temperature and will be
allowed to start again when the temperature rises 5°F above the setpoint.

Application Considerations
Exhaust/Return Fan Options
When is it necessary to provide building exhaust? Whenever an outdoor air economizer is used,
a building generally requires an exhaust system.The purpose of the exhaust system is to exhaust
the proper amount of air to prevent over or under-pressurization of the building.The goal is to
exhaust approximately 10% less air than the amount of outside air going into the building.This
maintains a slightly positive building pressure.
The reason for applying either a return, or exhaust fan is to control building pressure.TheTrane
100% modulating exhaust system with Statitrac is an excellent choice for controlling building
pressure in the majority of applications. For more demanding applications,Trane's 100%
modulating return fan system with Statitrac is an excellent choice for systems with high return
static pressure losses, or duct returns. Both systems employ direct digital control technology to
maintain building pressure. Either return or exhaust fan systems with Statitrac may be used on any
rooftop application that has an outdoor air economizer.
A building may have all or part of its exhaust system in the rooftop unit. Often, a building provides
exhaust external to the air conditioning equipment.This external exhaust must be considered
when selecting the rooftop exhaust system.
With an exhaust fan system, the supply fan motor and drives must be sized to overcome the total
system static pressure, including return losses, and pull return air back to the unit during noneconomizer operation. However, a supply fan can typically overcome return duct losses more
efficiently than a return air fan system. Essentially, one large fan by itself is normally more efficient
than two fans in series because of only one drive loss, not two as with return fan systems.
In a return fan system, the return fan is in series with the supply fan, and operates continuously
whenever the supply fan is operating to maintain return air volume.The supply fan motor and
drives are sized to deliver the design CFM based on internal and discharge static pressure losses
only.The return fan motor and drives are sized to pull the return CFM back to the unit based on
return duct static.Therefore, with a return fan system, the supply fan ordinarily requires less
horsepower than a system with an exhaust fan

Exhaust/Return Fan Systems
1. 100% modulating exhaust with Statitrac direct space sensing building pressurization control
(with or without exhaust variable frequency drives)
2. 100% modulating exhaust without Statitrac
3. 100% modulating plenum return airfoil fan with Statitrac direct space sensing building
pressurization control with variable frequency drive

4. 100% modulating plenum return airfoil fan without Statitrac
Drivers for applying either return or exhaust fan systems include economy, building pressure
control, code requirements, and generally accepted engineering practices.

Application Recommendations
100% Modulating Exhaust with Statitrac Control, CV and VAV Units
For both CV and VAV rooftops, the 100% modulating exhaust discharge dampers (or VFD) are
modulated in response to building pressure. A differential pressure control system, Statitrac, uses
a differential pressure transducer to compare indoor building pressure to atmospheric pressure.
The FC exhaust fan is turned on when required to lower building static pressure to setpoint.The
Statitrac control system then modulates the discharge dampers (or VFD) to control the building
pressure to within the adjustable, specified deadband that is set at the human interface panel.
Economizer and return air dampers are modulated independent of the exhaust dampers (or VFD)
based on ventilation control and economizer cooling requests.

RT-PRC027T-EN

41

RT-PRC027.book Page 42 Tuesday, October 7, 2014 9:03 AM

Application Considerations

Advantages:
•

The exhaust fan runs only when needed to lower building static pressure.

•

Statitrac compensates for pressure variations within the building from remote exhaust fans and
makeup air units.

•

The exhaust fan discharges in a single direction resulting in more efficient fan operation
compared to return fan systems.

•

When discharge dampers are utilized to modulate the exhaust airflow, the exhaust fan may be
running unloaded whenever the economizer dampers are less than 100% open.

TheTrane 100% modulating exhaust system with Statitrac provides efficient control of building
pressure in most applications simply because 100 percent modulating exhaust discharge dampers
(or VFD) are controlled directly from building pressure, rather than from an indirect indicator of
building pressure, such as outdoor air damper position.

100% Modulating Exhaust System without Statitrac, CV Units Only
This fan system has performance capabilities equal to the supply fan.The FC exhaust fans are
started by the economizer's outdoor air damper position and the exhaust dampers track the
economizer outdoor air damper position.The amount of air exhausted by this fan is controlled by
modulating discharge dampers at the fan outlet.The discharge damper position is controlled by
a signal that varies with the position of the economizer dampers. When the exhaust fans start, the
modulating discharge dampers are fully closed, and exhaust airflow is 15 to 20% of total exhaust
capabilities.

100% Modulating Exhaust with or without Statitrac Control, SZVAV Units
The overall scheme will remain very similar to non-Single Zone VAV units with Space Pressure
Control with the exception of the dynamic Exhaust Enable Setpoint.
For SZVAV the user will select an Exhaust Enable Setpoint during the 100% Fan Speed Command.
Once selected, the difference between the Exhaust Enable Setpoint and Design OA Damper
Minimum Position at 100% Fan Speed Command will be calculated.The difference calculated will
be used as an offset to be added to the Active Building Design OA Minimum PositionTarget to
calculate the dynamic Exhaust EnableTarget to be used throughout the Supply Fan Speed/OA
Damper Position range.

Advantages:
•

The exhaust fan runs only when the economizer reaches the desired exhaust enable point.

•

Exhaust dampers are modulated based on the economizer position.

•

The exhaust fan discharges in a single direction resulting in more efficient fan operation
compared to return fan systems.

•

When discharge dampers are utilized to modulate the exhaust airflow, the exhaust fan may be
running unloaded whenever the economizer dampers are less than 100% open.

TheTrane 100% modulating exhaust system provides excellent linear control of building exhaust
in most applications where maintaining building pressure is not important.

100% Modulating Return Fan Systems with Statitrac Control, CV and
VAV units
For both CV and VAV applications, the IntelliPak II rooftop unit offers 100% modulating return fan
systems. A differential pressure control system, Statitrac, uses a differential pressure transducer
to compare indoor building pressure to atmospheric pressure.
The return fan exhaust dampers are modulated, based on space pressure, to control the building
pressure to within the adjustable, specified deadband that is set at the Human Interface Panel. A
VFD modulates the return fan speed based on return duct static pressure.

RT-PRC027T-EN

RT-PRC027.book Page 43 Tuesday, October 7, 2014 9:03 AM

Application Considerations

Economizer and return air dampers are modulated independent of the exhaust dampers based on
ventilation control and economizer cooling requests.

Advantages:
•

The return fan operates independently of the supply fan to provide proper balance throughout
the airflow envelope.

•

Statitrac compensates for pressure variations within the building from remote exhaust fans and
makeup air units.

•

The return fan acts as both exhaust and return fan based on operation requirements.

TheTrane 100% modulating return system with Statitrac provides efficient control of building
pressure in applications with higher return duct static pressure and applications requiring duct
returns. Exhaust discharge dampers are controlled directly from building pressure, return fan VFD
is controlled from return static pressure, and return/economizer dampers are controlled based on
ventilation control and economizer cooling requests.

100% Modulating Return Fan without Statitrac Control, CV Units Only
The exhaust discharge dampers are modulated in response to building pressure.The return fan
runs continuously while the supply fan is energized. Economizer and return air dampers are
modulated independent of the exhaust dampers based on ventilation control, and economizer
cooling requests.

Advantages:
•

The exhaust dampers are modulated as needed through a space pressure sensor input to
maintain building pressure.

•

The return fan discharges in two directions, thereby balancing exhaust and unit return air
volumes.

Other Cooling Options
Cooling, Rapid Restart Units Only
This is for applications where the space has a high heat load with critical temperature control
requirements. A typical application is a computer room that has a large number of routers and
servers. If the cooling capacity is lost due to a power interruption, the temperature in the room can
rise as much as 3-4°F per minute. Once power is restored (e.g., backup generator has started), the
cooling capacity needs to be maximized as soon as possible to help get the space under control.
Once cooling capacity has been maximized, the unit can then manage the load using its normal
capacity control algorithms.

Supply and Return Airflow Configurations
The typical rooftop installation has both the supply and return air paths routed through the roof
curb and building roof. However, many rooftop installations require horizontal supply and/or return
from the rooftop because of a building's unique design or for acoustic considerations.
With IntelliPak II, there are several ways to accomplish horizontal supply, see Table 1, p. 44 and/or
return, see Table 2, p. 45.

When using an IntelliPak II rooftop for horizontal supply and/or return, an additional pressure drop
must be added to the supply external static to account for the 90 degree turn the air is making.This
additional pressure drop depends on airflow and rooftop size, but a range of 0.10 inches to 0.30
inches can be expected.The openings on the rooftop all have a one inch lip around the perimeter
to facilitate ductwork attachment.

Corrosive Atmospheres
Trane's IntelliPak rooftops are designed and built to industrial standards and will perform to those
standards for an extended period depending on the hours of use, the quality of maintenance
performed, and the regularity of that maintenance. One factor that can have an adverse effect on
unit life is its operation in a corrosive environment. Since the microchannel condenser coil is an
all-aluminum design, it provides a high level of corrosion protection on its own. Uncoated, it
withstands a salt spray test in accordance with ASTM B117 for 1,000 hours. When rooftops are
operated in highly corrosive environments,Trane recommends the corrosion protected condenser
coil option.
This corrosion protection option meets the most stringent testing in the industry, including ASTM
B117 Salt Spray test for 6,000 hours and ASTM G85 A2 Cyclic Acidified Salt Fog test for 2,400 hours.
The acid fog test is the most stringent available today.This coating is added after coil construction
covering all tubes, headers, fins and edges.The design provides superior protection from any
corrosive agent. For evaporator coils, copper fins can be utilized as a design special.
Note: Field coating is not allowed on Microchannel coils.

Ventilation Override Sequences
One of the benefits of using an exhaust fan rather than a return fan, in addition to the benefits of
lower energy usage and improved building pressurization control, is that the rooftop can be used
as part of a ventilation override system. Several types of sequences can be easily done when
exhaust fans are a part of the rooftop system.
What would initiate the ventilation override control sequence?Typically, a manual switch is used
and located near the fire protection control panel.This enables the fire department access to the
control for use during or after a fire. It is also possible to initiate the sequence from a field-installed
automatic smoke detector. In either case, a contact closure begins the ventilation override control
sequence.
Trane can provide five (5) different ventilation override sequences on both CV and VAV IntelliPak
II rooftops. For convenience, the sequences are factory preset but are fully field edited from the
Human Interface Panel orTracer. Any or all five sequences may be “locked” in by the user at the
Human Interface Panel.
The user can customize up to five (5) different override sequences for purposes such as smoke
control.The following parameters within the unit can be defined for each of the five sequences:
• Supply Fan - on/off
• Variable Frequency Drives - on (60 Hz)/off (0 Hz)/controlling
• Exhaust/Return Fan - on/off
• Exhaust Dampers - open/closed

Compressors and condenser fans are shut down for any Ventilation Override sequence. Factory
preset sequences include unit Off, Exhaust, Purge, Purge with duct pressure control, and
Pressurization. Any of the user-defined Ventilation Override sequences can be initiated by closing
a field supplied switch or contacts connected to an input on the Ventilation Override Module. If
more than one ventilation override sequence is being requested, the sequence with the highest
priority is initiated. Refer to the Ventilation Override Module (VOM) information in the Control
section of this catalog for more details on each override sequence.

Natural Gas Heating Considerations
Trane uses heavy gauge 304 L stainless steel throughout the construction of its natural gas drum
and tube heat exchangers for the IntelliPak II product.These heat exchangers can be applied with
confidence, particularly with full modulation control, when mixed air temperatures are below
50°F, and low ambient temperatures can cause condensation to form on the heat exchanger.
IntelliPak II natural gas heat exchangers are not recommended for applications with mixed air
conditions entering the heat exchanger below 30°F to ensure adequate leaving air heating
temperature. For airflow limitations and temperature rise across the heat exchanger information,
see Table 42, p. 137.

Acoustical Considerations
The ideal time to make provisions to reduce sound transmission to the space is during the project
design phase. Proper placement of rooftop equipment is critical to reducing transmitted sound
levels to the building.The most economical means of avoiding an acoustical problem is to place
any rooftop equipment away from acoustically critical areas. If possible, rooftop equipment should
not be located directly above areas such as: offices, conference rooms, executive office areas and
classrooms. Ideal locations are above corridors, utility rooms, toilet facilities, or other areas where
higher sound levels are acceptable.
Several basic guidelines for unit placement should be followed to minimize sound transmission
through the building structure:

1. Never cantilever the condensing section of the unit. A structural cross member must support
this end of the unit.
2. Locate the unit's center of gravity close to or over a column or main support beam to minimize
roof deflection and vibratory noise.

3. If the roof structure is very light, roof joists should be replaced by a structural shape in the critical
areas described above.

4. If several units are to be placed on one span, they should be staggered to reduce deflection over
that span.
It is impossible to totally quantify the effect of building structure on sound transmission, since this
depends on the response of the roof and building members to the sound and vibration of the unit
components. However, the guidelines listed above are experience proven guidelines which will
help reduce sound transmission.The ASHRAE publication "A Practical Guide to Noise and
Vibration Control for HVAC Systems" also provides valuable information.
There are several other sources of unit sound, i.e., supply fan, compressors, exhaust/return fans,
condenser fans and aerodynamic noise generated at the duct fittings. Refer to the ASHRAE
Applications Handbook, Chapter 47, 2003 edition for guidelines for minimizing the generation of
aerodynamic noise associated with duct fittings. A good source of information on general
acoustical considerations for rooftops is the 2000 ASHRAE Journal article titled, "Controlling Noise
from Large Rooftop Units".
TheTrane Acoustic Program (TAP) allows complete modeling of rooftop acoustical installation
parameters.The software models airborne sound from supply and return ducts, as well as duct

and make design alterations before equipment installation. Output of the program shows the
resulting NC (or RC) level for any point in the occupied space.TAP is also capable of modeling the
effect of outdoor sound on the surrounding area.This program is available fromTrane's Customer
Direct Service Network (C.D.S.), ask your localTrane representative for additional information on
this program.

Clearance Requirements
The recommended clearances identified in Figure 40, p. 176 should be maintained to assure
adequate service capability, maximum capacity and peak operating efficiency. A reduction in unit
clearance could result in condenser coil starvation or warm condenser air recirculation. If the
clearances shown are not possible on a particular job, consider the following:
• Do the clearances available allow for major service work such as changing compressors or
coils?
• Do the clearances available allow for proper outside air intake, exhaust air removal and
condenser airflow?
• If screening around the unit is being used, is there a possibility of air recirculation from the
exhaust to the outside air intake or from condenser exhaust to condenser intake?
Actual clearances which appear inadequate should be reviewed with a localTrane sales engineer.
When two or more units are to be placed side by side, the distance between the units should be
increased to 150 percent of the recommended single unit clearance.The units should also be
staggered, see Figure 23, for two reasons:

1. To reduce span deflection if more than one unit is placed on a single span. Reducing deflection
discourages sound transmission.

2. To assure proper diffusion of exhaust air before contact with the outside air intake of adjacent
unit.

Application Considerations

Duct Design
It is important to note that the rated capacities of the rooftop can be met only if the rooftop is
properly installed in the field. A well-designed duct system is essential in meeting these capacities.
The satisfactory distribution of air throughout the system requires that there be an unrestricted and
uniform airflow from the rooftop discharge duct.This discharge section should be straight for at
least several duct diameters to allow the conversion of fan energy from velocity pressure to static
pressure.
However, when job conditions dictate elbows be installed near the rooftop outlet, the loss of
capacity and static pressure may be reduced through the use of guide vanes and proper direction
of the bend in the elbow.The high velocity side of the rooftop outlet should be directed at the
outside radius of the elbow rather than the inside as illustrated in Figure 24.
Figure 24. Duct design

IMPROPER

Energy Recovery Wheel
For applications where the air streams within the rooftop must be isolated, consider using
alternative technologies that guarantee separation of the air streams.
Important:

Do not use energy wheels in applications where the exhaust air is contaminated with
harmful toxins or biohazards or where even a minor mixing of the air streams
presents a health risk. See Installation Operation Maintenance (RT-SVX24*-EN) for
more information.

The energy recovery option was designed as a partial flow outside air system, where the required
outside air is less than 100 percent. IntelliPak II monitors outside air, return air, and zone conditions.
It compares them with setpoints (set in the rooftop human interface) and checks for suitable energy
recovery system operation. Energy recovery can be activated when both supply and exhaust fans
are in operation. Heat can be recovered when the return air dry bulb temperature is greater than
the outside air dry bulb temperature.
Energy recovery is disabled when economizer cooling operation is requested. Economizer cooling
in energy recovery wheel equipped units requires the exhaust air and outside air bypass dampers
to be open and the recovery wheel motor to be off.The energy recovery wheel can provide free
cooling when outside air enthalpy is greater than return air enthalpy. In general, energy recovery
works well in applications where a high outside airflow minimum is required, often because of high
occupancy.

Hot Gas Reheat
In general, applications where non-peak load conditions can be dominated by latent loads are
candidates for the dehumidification option.This includes many applications subject to ASHRAE
Standard 62 requirements.

Application Considerations

For applications where the unit is utilized as a make-up air or 100% outside air unit, please consider
using an alternate solution.These applications are not appropriate for theTrane dehumidification
option with hot gas reheat.

Evaporative Condenser
Water Supply—Suspended particulate matter, mineral concentrations, trash and debris can
adversely affect performance of any water-cooled device. If not managed, mineral concentrations
can result in clogged water system hardware, heat exchanger restriction and heat transfer loss.
Trane's evaporative condenser is designed to greatly minimize performance problems that may
occur from the by-products of water evaporation.
Incoming Water Supply Line—A float valve is provided to maintain sump water level during
condenser operation. A field installed gate valve may be installed on the condenser water supply
line. An 80 to 100 mesh field supplied strainer may be installed in the condenser water supply line
to help prevent the introduction of debris.The condenser water supply line should be flushed
thoroughly prior to connection to the unit. Local codes may require back-flow prevention on the
condenser water supply line.
Water Discharge and Drain Line—Care and judgment should be exercised in selecting a water
discharge site.
Local Site Discharge—Rooftop or simple storm sewer discharge is generally acceptable. Do not
routinely direct sump discharge onto areas where the byproducts of water evaporation or water
treatment products are undesirable.
Sewer Discharge—The quantities of mineral and debris in the discharge water are actually very
small, and do not cause problems when diluted in normal sewer flow. Check local codes to identify
any special requirements for sewer discharge.
Regardless of the disposal method used, local codes, state or federal standards for water disposal
must be followed.
Freeze Protection—For operation in ambient temperatures below 32°F, optional sump heater and
controls are available to provide operation down to 10°F. In colder climates water supply line and
drain piping will require field installed freeze protection. Generally low wattage heat tape on the
water lines is sufficient protection.
Make-up Water Considerations:
Water Saving Methods—A programmable flush cycle is initiated to remove mineral deposits and
particulates from the sump.
Fresh water can be cycled into the sump as a portion of the existing water is drained.The intervals
between drains are adjustable from 0 - 12 hours.When set to 0, the periodic blowdown is disabled.
A more efficient approach is utilizing the Conductivity Controller option, which performs
blowdowns based on water quality readings from the conductivity sensor in the sampling tube.
Users can set a limit based on water quality testing they have performed in their area, when this
adjustable setpoint is exceeded the unit will conduct a blowdown for a period of time set by the
user.This allows the user to save water by only performing blowdowns when they are required.
Water level is maintained by the internal float valve.
WaterTreatment—Water treatment is required on all evaporative condensing units. Even when an
optional Dolphin WaterCare System is utilized, water must still be maintained and monitored
throughout the unit life cycle.
Note: Local codes may require the use of chemicals for water treatment. Different chemical feeder
systems are available to fit a wide variety of requirements and budgets. Check with local
code officials to determine installation requirements.

Low Ambient Operation— Remote Human Interface Recommendation
For low ambient operation, the use of a remote mounted human interface panel is recommend for
service and troubleshooting.

Selection Procedure

Cooling Capacity Selection
Step 1—Nominal Unit Size Selection
A summation of the peak cooling load and the outside air ventilation load shows: 980 MBh + 154.0
MBh = 1134.0 MBh required unit capacity.
From Table 10, p. 68, a 105 ton unit with standard capacity evaporator coil at 80 DB / 65 WB, 95°F
outdoor air temperature and 36,000 total supply CFM is 1,237 MBh total and 1,037 MBh sensible.
Thus, a nominal 105 ton unit with standard capacity evaporator coil is selected.

Step 2—Evaporator Coil Entering Conditions
Mixed air dry bulb temperature determination:
Using the minimum percent of OA (3,600 CFM ÷ 36,000 CFM = 10%), determine the mixture dry bulb
to the evaporator.
RADB + % OA (OADB - RADB) = 78 + (0.10) (95 - 78) = 78 + 1.5 = 79.5°F
Approximate wet bulb mixture temperature:
RAWB + % OA (OAWB - RAWB) = 65 + (0.10) (76 - 65) = 65 + 1.1 = 66.1°F

Step 3 - Determine Supply Fan Motor Heat Gain
Having selected a nominal 105 ton unit, the supply fan bhp can be calculated.The supply fan motor
heat gain must be considered in final determination of unit capacity.

Using total of 36,000 CFM and total static pressure of 4.0 inches, enter Table 33, p. 114.The table
shows 40.4 bhp with 1,097 rpm required for the 36" supply fan.
From Figure 25, p. 53 supply fan motor heat gain =
109.0 MBh, or 109.0 MBh ÷ 36000 CFM x 1.085 = 2.8°F supply fan motor heat

Step 4 - Determine Total Required Cooling Capacity
Required capacity =Total peak load + OA load + supply air fan motor heat
Required capacity = 980.0 + 154.0 + 109.0 = 1243.0 MBh (103.6 tons)

Step 5 - Determine Unit Capacity
From Table 10, p. 68, unit total capacity at 79.5 DB/66.1 WB entering the evaporator, 36,000 supply
air CFM, 95°F outdoor ambient is 1,251 MBh (104.2 tons) with 996 MBh (83 tons) sensible capacity.

Step 6 - Determine Leaving Air Temperature
Unit sensible heat capacity corrected for supply air fan motor heat = 996 MBh sensible - 109.0 MBh
motor heat = 887 MBh.

Selection Procedure

Supply air dry bulb temperature difference =

=

Sensible Btu = 887 MBh /(1.085 x 36,000 CFM) = 23.0

Total Btu

=

Unit enthalpy difference = 1,251 MBh ÷ (4.5 x 36,000 CFM) = 7.72 Btu/lb.
Leaving enthalpy = h (ent WB) - h (diff). From Table 6, p. 64 h (ent WB) = 30.9 Btu/lb.
Leaving enthalpy = 30.9 Btu/lb. - 7.72 Btu/lb. = 23.18 Btu/lb.
Supply air wet bulb = 54.9 leaving evaporator coil.
Leaving air temperature = 56.5 DB/54.9 WB

Heating Capacity Selection
Step 1 - Determine Air Temperature Entering Heating Module
Mixed air temperature = RADB + % OA (OADB - RADB) = 70 + (0.10) (0 - 70) = 63°F
Supply air fan motor heat temperature rise = 109000 Btu ÷ (1.085 x 36000 CFM) = 2.8°F
Air temperature entering heating module = 63.0 + 2.8 = 65.8°F

Step 2 - Determine Total Winter Heating Load
Total winter heating load =
peak heating load + ventilation load - supply fan motor heat = 720 + 288.6 - 109.0 = 899.6 MBh

Electric Heating System
Unit operating on 460/60/3 power supply.
From Table 58, p. 151, kW may be selected for a nominal 105 ton unit operating 460-volt power.The
265 kW heat module (904.4 MBh) will satisfy the winter heating load of 899.6 MBh.
Table 42, p. 137 shows an air temperature rise of 23.2°F for 36,000 CFM through the 265 kW heat
module.
Unit supply temperature at design heating conditions = mixed air temperature +
air temperature rise = 65.8°F + 23.2°F = 89.0°F.

Gas Heating System (Natural Gas)
From Table 42, p. 137 select the high heat module (1,440 MBh output) to satisfy winter heating load
of 899.6 MBh at unit CFM.
Table Table 42, p. 137 also shows an air temperature rise of 37.0°F for 36,000 CFM through the
heating module.
Unit supply temperature at design heating conditions =
mixed air temperature + air temperature rise = 65.8°F + 37.0°F = 102.8°F.

Hot Water Heating System
Assume a hot water supply temperature of 190°F and an entering coil temperature of 65.8°F.
Subtract the mixed air temperature from the hot water temperature to determine the ITD (initial
temperature difference).
ITD = 190°F - 65.0°F = 125°F. Divide the winter heating load by ITD = 1008.6 MBh ÷ 125°F = 8.0 Q/ITD.
From Table 45, p. 138, select the low heat module. By interpolation, a Q/ITD of 8.0 can be obtained
at a gpm of 40.0. Water pressure drop at 40.0 gpm is 0.33 ft. of water.

determination, system external static must be added to appropriate component static pressure
drop (evaporator coil, filters, optional economizer, optional exhaust fan, optional heating system,
optional cooling only extended casing).

Selection Procedure

Supply Fan Motor Sizing
The supply fan motor selected in the cooling capacity determination was 40.4 bhp and 1,097 rpm.
Thus, a 40 hp supply fan motor is selected.
Enter Table 53, p. 147 to select the proper drive. For a 105 ton rooftop with 40 hp motor, a drive letter
A - 1,100 rpm is selected.

Exhaust Fan Motor Sizing
The exhaust/return fan is selected based on total return system negative static pressure and
exhaust fan CFM. Return system negative static includes return duct static, and any other job site
applicable static pressure drop.
Return duct static pressure = 0.30 inches.
Total return system negative static pressure = 0.30 inches.
Exhaust fan CFM = 36,000 CFM
From Table 38, p. 129 the required bhp is 21.44 bhp at 400 rpm.Thus, the exhaust fan motor
selected is 25 hp.
To select a drive, enter Table 54, p. 148 for a 25 hp motor for a 105 ton unit. Drive selection number
4 - 400 rpm.

Return Fan Motor Sizing
Return fan drive selection is shown on Table 55, p. 148.The same static pressure and CFM
considerations must be taken for return fan size, horsepower, and drive selection as are required
for exhaust fan sizing. However, since the return fan runs continuously the sensible heat generated
by the return fan motor must be included in the entering evaporator coil mixed air temperature
equation.
In this selection, if the return motor bhp is equal to the exhaust motor bhp, 21.44 bhp = 58.1 MBh
÷ (1.085 x 36,000 Return CFM) = 1.5°F added to the return air temperature.
Where altitudes are significantly above sea level, use Table 7, p. 65 Table 8, p. 65 and Figure 26,
p. 64 for applicable correction factors.

Unit Electrical Requirements
Selection procedures for electrical requirements for wire sizing amps, maximum fuse sizing, and
dual element fuses are given in the electrical service section of this catalog.

Altitude Corrections
The rooftop performance tables and curves of this catalog are based on standard air (.075 lbs/ft).
If the rooftop airflow requirements are at other than standard conditions (sea level), an air density
correction is needed to project accurate unit performance.
Figure 26, p. 64 shows the air density ratio at various temperatures and elevations.Trane rooftops
are designed to operate between 40° and 90°F leaving air temperature.
The procedure to use when selecting a supply or exhaust/return fan on a rooftop for elevations and
temperatures other than standard is as follows:

1. First, determine the air density ratio using Figure 26, p. 64.
2. Divide the static pressure at the nonstandard condition by the air density ratio to obtain the
corrected static pressure.

3. Use the actual CFM and the corrected static pressure to determine the fan rpm and bhp from
the rooftop performance tables or curves.

4. The fan rpm is correct as selected.
5. bhp must be multiplied by the air density ratio to obtain the actual operating bhp.

RT-PRC027T-EN

RT-PRC027.book Page 55 Tuesday, October 7, 2014 9:03 AM

Selection Procedure

In order to better illustrate this procedure, the following example is used:
Consider a 90 ton rooftop unit that is to deliver 32,000 actual CFM at 3-inches total static pressure
(tsp), 55°F leaving air temperature, at an elevation of 5,000 ft.

1. From Figure 26, p. 64, the air density ratio is 0.86.
2. Tsp = 3.0-inches / 0.86 = 3.49 inches tsp.
3. From fan performance table Table 33, p. 114 a 90 ton rooftop will deliver 32,000 CFM at 3.49
inchesTSP at 997 rpm and 30.27 bhp.
4. The rpm is correct as selected - 997 rpm.
5. bhp = 30.27 x 0.86 = 26.3 bhp actual.
Compressor MBh, SHR, and kW should be calculated at standard and then converted to actual
using the correction factors in Table 7, p. 65. Apply these factors to the capacities selected at
standard CFM so as to correct for the reduced mass flow rate across the condenser.
Heat selections other than gas heat will not be affected by altitude. Nominal gas capacity (output)
should be multiplied by the factors given in Table 8, p. 65 before calculating the heating supply air
temperature.

Evaporative Condensing Rooftop
For unit selection, air-cooled or evaporative condensers can be selected using the same
calculations, however evaporative condenser capacities should be calculated based on Wet Bulb
(WB) temperatures. For specific model selection, utilizeTOPSS or contact the localTrane Sales
Office.

Total Energy Recovery Wheel
UtilizeTOPSS or contact the localTrane sales office to calculate required return air preheat
temperature for the given minimum outdoor air temperature and return air relative humidity.
To calculate the supply and exhaust air conditions leaving the wheel, you must know the wheel
effectiveness. Refer to Table 52, p. 146 for total effectiveness measurements.
Note: The effectiveness numbers shown assume equal supply and exhaust airflows. If the
airflows are unbalanced, the effectiveness changes. UseTOPSS to determine effectiveness
values for these conditions.

Calculate Wheel Performance
Use the following equations to calculate supply air conditions. UseTOPSS to calculate exhaust air
conditions and to obtain actual dry bulb temperature and enthalpy values for coil and equipment
sizing.

Dry Bulb Temperature:
Cooling:Tsa =Toa - (E x (Toa-Tra))
Heating:Tsa =Toa + (E x (Tra-Toa))
where:
Tsa = Dry bulb temperature of supply air (°F)
Toa = Dry bulb temperature of outside air (°F)
Tra = Dry bulb temperature of return air (°F)
E = Sensible Effectiveness

Enthalpy:
Cooling: Hsa = Hoa - (E x (Hoa-Hra))

RT-PRC027T-EN

55

RT-PRC027.book Page 56 Tuesday, October 7, 2014 9:03 AM

Selection Procedure

Heating: Hsa = Hoa + (E x (Hra-Hoa))
where:
Hsa = Enthalpy of supply air (Btu/ lb)
Hoa = Enthalpy of outside air (Btu/ lb)
Hra = Enthalpy of return air (Btu/lb)
E =Total Effectiveness
After calculating these two points, use a psychrometric chart to obtain the supply air wet bulb
temperature and/or grains moisture.

Energy Wheel Application Example
In this example, a wheel sized for nominal 10,500 CFM will be used for the initial evaluation.The
air pressure drop is 1.07 in. wg and the total effectiveness is 73% (see Table 52, p. 146).The total
and latent effectiveness values are close to equal forTrane energy wheels. For this example, total
effectiveness is assumed to be 73% in cooling mode and 75% in heating mode.TOPSS could be
used to obtain the exact values.

Supply Air Conditions, Cooling Mode:
Tsa =Toa - (E x (Toa -Tra)) = 95°F - (.73 x (95°F - 75°F))= 81°F
Hsa = Hoa - (E x (Hoa - Hra)) = 38.4 Btu/lb - (.73 x (38.4 Btu/ lb - 26.0 Btu/lb) = 29.3 Btu/lb
According to a psychrometric chart, the supply air wet bulb temperature is 64.4°F, 64 grains/lbm.
Tsa =Toa + (E x (Tra -Toa)) = 10°F + (.75 x (70°F - 10°F)) = 55°F
Hsa = Hoa + (E x (Hra - Hoa)) = 3.2 Btu/lb + (.75 x (22.7 Btu/lb -3.2 Btu/lb)) = 17.8 Btu/lb
According to a psychrometric chart, the supply air wet bulb temperature is 45.5°F, 30 grains/lbm.
When designing the remainder of the air-handling system, remember to account for the air
pressure drop imposed by the energy wheel.

Hot Gas Reheat Dehumidification Selection
This option allows for increased outdoor air ventilation. It reduces humidity levels while increasing
comfort level in the air space. Cooling can operate without a demand for dehumidification.The hot
gas reheat coil is designed to deliver maximum reheat temperatures.
Contact the localTrane Sales Office or refer to the IntelliPak IITOPSS selection program to
determine leaving air temperature, latent capacity, reheat sensible capacity, leaving unit dew point,
and moisture removal when the unit is in reheat operation. Please note that reheat operation will
not be allowed when there is a call for cooling or heating.

Notes:
1. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static pressure must be
added to appropriate component sp drops (evap coil, filters, optional economizer, optional heating system).
2. Maximum SP leaving the rooftop is 5.5" H20 positive.
3. Max CFM allowable CFM is 31000
4. Max rpm 2000, Max hp 50
5. Min rpm 1400, Min hp 15
(a) Outlined area indicates nonstandard bhp or rpm selections. Contact a local Trane representative for more information.

Notes:
1. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static
pressure must be added to appropriate component sp drops (evap coil, filters, optional economizer, optional heating system).
2. Maximum SP leaving the rooftop is 5.5" H20 positive.
3. Max CFM for 90T is 40000 CFM, 105T 45000
4. Max rpm 1300, Max hp 60 for 90T. Max rpm 1350, Max hp 75 for 105T
5. Min rpm 750; Min hp 15 for 90T, Min hp 20 for 105T
(a) Outlined area indicates nonstandard bhp or rpm selections. Contact a local Trane representative for more information.

Notes:
1. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external
static pressure must be added to appropriate component sp drops (evap coil, filters, optional economizer, optional heating
system).
2. Maximum SP leaving the rooftop is 5.5" H20 positive.
3. Max CFM as follows: 105T 36000 CFM; 120T 42000 CFM, 130T and 150T 45000 CFM.
4. Max rpm 1500, Max hp 60
5. Min rpm 900, Min hp 15 for 105-120T, Min hp 20 for 130-150T
(a) Outlined area indicates nonstandard bhp or rpm selections. Contact a local Trane representative for more information.

Electrical Data
Electrical Service Sizing
To correctly size electrical service wiring for a unit, find the appropriate calculations listed below.
Each type of unit has its own set of calculations for MCA (Minimum Circuit Ampacity), MOP
(Maximum Overcurrent Protection), and RDE (Recommended Dual Element fuse size). Read the
load definitions that follow and then find the appropriate set of calculations based on unit type.
Note: Set 1 is for cooling only and cooling with gas heat units, and set 2 is for cooling with electric
heat units.
Load Definitions: (To determine load values, see the Electrical Service Sizing DataTables on the
following page.)
LOAD1 = CURRENT OFTHE LARGEST MOTOR (COMPRESSOR OR FAN MOTOR)
LOAD2 = SUM OFTHE CURRENTS OF ALL REMAINING MOTORS
LOAD3 = CURRENT OF ELECTRIC HEATERS
LOAD4 = ANY OTHER LOAD RATED AT 1 AMP OR MORE

Set 1. Cooling Only Rooftop Units and Cooling with Gas Heat Rooftop Units
MCA = (1.25 x LOAD1) + LOAD2 + LOAD4
MOP = (2.25 x LOAD1) + LOAD2 + LOAD4
Select a fuse rating equal to the MOP value. If the MOP value does not equal a standard fuse size
as listed in NEC 240-6, select the next lower standard fuse rating.
Note: If selected MOP is less than the MCA, then select the lowest standard maximum fuse size
which is equal to or larger than the MCA, provided the selected fuse size does not exceed
800 amps.
RDE = (1.5 x LOAD1) + LOAD2 + LOAD4
Select a fuse rating equal to the RDE value. If the RDE value does not equal a standard fuse size as
listed in NEC 240-6, select the next higher standard fuse rating.
Note: If the selected RDE is greater than the selected MOP value, then select the RDE value to equal
the MOP value.

Set 2. Rooftop units with Electric Heat
To arrive at the correct MCA, MOP, and RDE values for these units, two sets of calculations must
be performed. First calculate the MCA, MOP, and RDE values as if the unit was in cooling mode (use
the equations given in Set 1).Then calculate the MCA, MOP, and RDE values as if the unit were in
the heating mode as follows.
(Keep in mind when determining LOADS that the compressors don't run while the unit is in the
heating mode).
MCA = 1.25 x (LOAD1 + LOAD2 + LOAD4) + LOAD3
The nameplate MCA value will be the larger of the cooling mode MCA value or the heating mode
MCA value calculated above.
MOP = (2.25 x LOAD1) + LOAD2 + LOAD3 + LOAD4
The selection MOP value will be the larger of the cooling mode MOP value or the heating mode
MOP value calculated above.
Select a fuse rating equal to the MOP value. If the MOP value does not equal a standard fuse size
as listed in NEC 240-6, select the next lower standard fuse rating.
Note: If selected MOP is less than the MCA, then select the lowest standard maximum fuse size
which is equal to or larger than the MCA, provided the selected fuse size does not exceed
800 amps.
RDE = (1.5 x LOAD1) + LOAD2 + LOAD3 + LOAD4

Electrical Data

The selection RDE value will be the larger of the cooling mode RDE value or the heating mode RDE
value calculated above.
Select a fuse rating equal to the RDE value. If the RDE value does not equal a standard fuse size as
listed in NEC 240-6, select the next higher standard fuse rating.
Notes:
•

If the selected RDE is greater than the selected MOP value, then select the RDE value to equal
the MOP value.

•

On 90 to 162 ton rooftops, the selected MOP value is stamped in the MOP field on the unit
nameplate.
