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 EA-

Credit 4 requirements. Bottom line, less refrigerant is

being used, which creates a healthier and greener

environment.

Features & Benefits

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.

Features & Benefits

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.

Features & Benefits

Superior Control Options

Integrated Comfort with TraneTracer LCI and BCI

TheTracer Integrated Comfort™ System (ICS) or System Controller (SC) improves job profit and

increases job control by combiningTrane rooftop units with theTraneTracer building management

system.These integrated systems provide total building comfort and control. Some of the primary

motivations for building owners/managers in deciding to purchase a HVAC controls system are

energy savings, cost control, and the convenience of facility automation.

Simplifying the Comfort System

Trane technology and innovation brings more capabilities, more flexibility, and offers equipment

and systems that are easy to use, easy to install, commission and service.TheTracer Integrated

Comfort system and System Controller save time and money by simplifying system design and

system installation.

When used withTrane DDC/VAV terminals (or VariTrane), system balancing almost goes away

because each VAV box is commissioned and tested before it leaves the factory. All the status

information and editing data from the rooftop units, VAV terminals, lighting, exhaust and other

auxiliary equipment is available fromTracer for facility control, monitoring and service support.

Tracer, a family of building automation products fromTrane, is designed with robust, application

specific software packages to minimize custom programming requirements and enable system

setup and control through simple editing of parameters in the standard applications software.

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

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.

Features & Benefits

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

Statitrac Direct Space Building

Pressurization Control

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.

4. Measure and read return duct static pressure.

Proper building pressurization eliminates annoying door whistling, doors standing open, and

odors from other zones.

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 time-

sensitive applications where extended down time is not an option and heating/cooling is crucial.

Controls

Variable Air Volume (VAV) Only

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 user-

defined 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

Controls

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

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 contacts connected to an changeover input on the RTM.

Controls

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 CO2sensor may be connected to the ventilation control module to control

outside air based on CO2Demand 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 theVFD 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.

Controls

Ventilation Control

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.

Controls

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.

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.

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-3waystoswitch 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

TheTrane Tracer 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.

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.

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 CO2level is greater than or equal to the CO2Design 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 CO2level is less than or equal to the CO2Minimum 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 CO2level is greater than the CO2Minimum Setpoint and less than the CO2Design

Setpoint, the outdoor air damper position is (or OA flow) modulated proportionally to the Space

CO2level relative to a point between the CO2Min Setpoint and the CO2Design Setpoint. If there

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.

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

(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.

Controls

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.

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.

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.

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 non-

economizer 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.

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

RT-PRC027T-EN 43

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 fanVFD

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.

RT-PRC027T-EN 45

Application Considerations

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

Application Considerations

• Economizer dampers - open/closed

• Heat - off/controlling (output for) VAV Boxes - open/controlling

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

RT-PRC027.book Page 46 Tuesday, October 7, 2014 9:03 AM

Application Considerations

breakout and roof transmission sound, so that the designer can identify potential sound problems

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.

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.

Supply Air Fan

Determine unit total static pressure at design supply CFM:

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

Supply air dry bulb = 79.5 DB - 23.0 = 56.5 leaving evaporator coil

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.

RT-PRC027T-EN 53

Selection Procedure

Heat module temperature rise is determined by:

Unit supply air temperature = mixed air temperature + air temperature rise = 65.4 + 25.8 = 91.2°F.

Steam Heating System

Assume a 15 psig steam supply.

From Table 46, p. 139, the saturated temperature steam is 250°F. Subtract mixed air temperature

from the steam temperature to determine ITD.

ITD = 250°F - 65.0°F = 185°F.

Divide winter heating load by ITD = 1008.6 MBh ÷ 185°F = 5.45 Q/ITD.

From Table 46, p. 139, select the low heat module.The low heat module at 36,000 CFM has a

Q/ITD = 7.45.

Heat module capacity, Q = ITD x Q/ITD = 185°F x 7.45 Q/ITD = 1378 MBh

Heat module air temperature rise is determined by:

Unit supply temperature at design conditions =

mixed air temperature + air temperature rise = 65.4°F + 35.3°F = 100.7°F.

Air Delivery Procedure

Supply fan performance tables include internal resistance of rooftop. For total static pressure

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-PRC027.book Page 54 Tuesday, October 7, 2014 9:03 AM

RT-PRC027T-EN 55

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

56 RT-PRC027T-EN

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 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=(1.5xLOAD1)+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=(1.5xLOAD1)+LOAD2+LOAD3+LOAD4

RT-PRC027.book Page 149 Tuesday, October 7, 2014 9:03 AM

150 RT-PRC027T-EN

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:
