Integrated Self-Contained Systems
Everything you need to know about your self-contained VAV system is available using Tracer,
Trane’s family of building automation products. Tracer is a software package that minimizes custom
programming requirements and allows easy system setup and control using your personal
computer. By enabling all CSC units to communicate using the LonTalk interface, transforming
your heating and cooling units into a true system is made simple.
Operating data from all system components is readily available for evaluation. You can control,
monitor, and service your facility—all from your personal computer. That is why all Tracer controls
have been designed to be LonTalk compatible.
The IntelliPak self-contained unit, as part of Trane ICS, provides powerful maintenance monitoring,
control, and reporting capabilities. Tracer places the self-contained unit in the appropriate
operating mode for: system on/off, night setback, demand limiting, setpoint adjustment based on
outside parameters and much more. You can monitor unit diagnostic conditions through Tracer
such as: sensor failures, loss of supply airflow, and an inoperative refrigerant circuit.
Integrated Comfort™ System (ICS)
Trane’s Integrated Comfort system (ICS) increases job control by
combining IntelliPak™ Signature Series self-contained units and
a Tracer™ building management system. This integrated system
provides total building comfort and control. Building owners
and managers not only save energy when using ICS. They have
the ability to automate their facilities and the convenience of a
control system interface.
Simplifying The Comfort System
Trane’s designers combined new technology and innovation to
bring you more system capabilities and flexibility. Our
Integrated Comfort System (ICS) with HVAC equipment is easy
to use, install, commission, and service.

Interoperability with BACnet™
The Trane Tracer SC BACnet Control Interface (BCI) for IntelliPak self-contained offers a building
automation control system with outstanding interoperability benefits. BACnet, which is an industry
standard, is an open, secure and reliable network communication protocol for controls, created by
American Society of Heating, refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE).
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 equipment with Tracer SC controls or a 3rd party
building automation system. It enables integration with many different building controls such as
access/intrusion monitoring, lighting, fire and smoke devices, energy management, and a wide
variety of sensors (temperature, pressure, humidity, occupancy, CO2 and air velocity).
Trane Wireless Comm Interface (WCI)
The Trane® Wireless Comm Interface (WCI) is the perfect alternative to Trane’s BACnet™ wired
communication links (for example, Comm links between a Tracer™ SC and a Tracer™ UC400).
Minimizing communication wire used 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.
PKG-PRC002U-EN 9
Features and Benefits
Trane R-410A 3-D™ Scroll Compressor
Features listed below optimize the compressor design and performance:
• Optimized scroll profile
• Heat shield protection to reduce heat transfer between discharge and suction gas
• Improved sealing between high side and low side
Additional features are incorporated in the compressor design for greater reliability:
• Patented design motor cap for improved motor cooling
• Improved bearing alignment
• Improved resistance to dry start-up
• Oil sight glass for evaluating proper oil levels
Low Torque Variation
The 3-D™ Scroll has a very smooth compression cycle, imposing very little stress on the motor and
resulting in greater reliability. Low torque variation reduces noise and vibration.
Suction Gas Cooled Motor
Compressor motor efficiency and reliability is further optimized with the latest scroll design. The
patented motor cap directs suction gas over the motor, resulting in cooler motor temperatures for
longer life and better efficiency.
Proven Design through Testing and Research
The new R-410A 3-D™ Scroll compressor is the next generation of reliable Trane 3-D™ Scroll
compressors provided by Trane, the leader in scroll compressor technology.
The R-410A Trane 3-D™ Scroll provides
important reliability and efficiency benefits
inherent in its design. The 3-D™ Scroll allows
the orbiting scrolls to touch in all three
dimensions, forming a completely enclosed
compression chamber which leads to increased
efficiency. In addition, the orbiting scrolls only
touch with enough force to create a seal,
eliminating wear between the scroll involutes.
The fixed and orbiting scrolls are made of high
strength cast iron which results in less thermal
distortion and minimal leakage. In addition,
improved part isolation provides reduced
compressor sound levels compared to previous
designs.

Application Considerations
Self-Contained Acoustical Recommendations
Successful acoustical results are dependent on many system design factors.
Following are general acoustical recommendations. For more information, or if there is concern
about a particular installation, contact a professional acoustical consultant.
Location and Orientation of the Mechanical Equipment Room
Locate the equipment room adjacent to stairwells, utility rooms, electrical closets, and rest rooms
if possible (See figure below). This minimizes the acoustic effects and risk of workmanship or
installation errors. Place the discharge and return air ductwork over these less acoustically
sensitive areas, using vertical or horizontal fresh air shafts. Consult code requirements for fresh air
and smoke purge constraints.
Return Air Ductwork
Duct the return air into the mechanical equipment room. Connect ductwork to the unit if local code
dictates. The return air ductwork must have an elbow inside the equipment room. This elbow will
reduce sound transmissions through the return duct. Extend the ductwork from the elbow far
enough to block the “line of sight” to the exterior of the equipment room. Use a minimum ductwork
length of 15 feet to the equipment room exterior. Line the duct with two-inch, three-pound density
insulation. Use multiple, small return ducts for better acoustical performance to the occupied
space.
Supply Air Ductwork
Insulate the supply air duct with two-inch, three-pound density insulation. Extend this lining at least
15 feet out from the equipment room wall, keeping the duct aspect ratio as small as possible.
Minimize large flat panels since they transmit sound. In addition, small aspect ratios will minimize
potential “oil canning” of the duct due to flow turbulence.
The flexible horizontal discharge plenum option helps avoid complicated ductwork transitions.
Ductwork turning vanes typically improve pressure drop but degrade acoustical performance.
Recommended Maximum Air Velocities
The maximum recommended velocity for the discharge air duct is 2,000 fpm. The maximum
recommended velocity for the return air duct is 1,000 fpm. Limit air velocities below these
operating points to minimize the risk of flow turbulence that causes regenerated noise. Using
round supply duct and static regain allows maximum discharge air velocities up to 3,000 fpm.
Lining round supply duct also substantially lowers frequency noise attenuation. However, flow
regenerated noise potential increases dramatically at air velocities over 3000 fpm.

Application Considerations
Equipment Room Construction Options
Locate the equipment room door away from acoustically sensitive areas like conference rooms.
The door should swing out of the equipment room, if possible, so that the low pressure in the
equipment room pulls the door in to help maintain a tight seal.
Equipment Options
The flexible horizontal discharge plenum allows multiple tested outlet options. This minimizes the
risk of acoustic and/or pressure drop problems by avoiding complex transitions close to the fan
discharge.
Static Pressure Versus Acoustics
Design the system to minimize the total static pressure required from the self-contained unit fan.
Typically a change in static pressure of only 0.5 inches can reduce NC level by approximately 2 or
3 in the occupied space.
Isolation Recommendations
Unit
The Signature Series unit fan and compressors are internally isolated. Therefore, external isolation
is not required. Consult a vibration specialist before considering external or double vibration
isolation.
Ductwork
Design duct connections to the unit using a flexible material. Consult local codes for approved
flexible duct material to prevent fire hazard potential.
Piping Connections
Rubber isolator connectors are recommended for condenser piping to prevent vibration
transmission to or from the building plumbing. The Signature Series self-contained unit is
internally isolated and does not require additional isolation. However, ensure proper system
vibration isolation design prevents vibration transmission from the building plumbing to the unit.
Also be sure to properly isolate the drain line.
Condenser Water Piping
Piping Location and Arrangement
Provide at least 24 inches of clearance between the piping and the unit for service. Place the risers
away from the side of the unit if possible. Be sure to allow sufficient space for valves and unions
between the piping and the self-contained unit. Lay out condenser piping in reverse returns to help
balance the system. This is accomplished by equalizing the supply and return pipe length. Multi-
The preferred equipment room wall construction is
concrete block. If this is not feasible then a double
stud offset wall is suggested (See figure). This
removes physical contact that would transmit sound
through the equipment room wall to the occupied
space. Interweave fiberglass insulation between the
wall studs. Use two layers of sheetrock on each side
of the wall.
Workmanship details are critical to acoustical
performance. Seal all wall and floor penetrations by
the ductwork, water piping, and equipment room
access doors with a flexible material such as caulk
and/or gasketing to stop noise and air leaks.
12 PKG-PRC002U-EN
Application Considerations
story buildings may use a direct return system with balancing valves at each floor. Install all heat
exchangers and most cooling tower piping below the sump operating water level to prevent
overflow during unit and/or system shut down.
Recommended Pump Location
Locate pump downstream of the cooling tower and upstream of the self-contained unit. This
provides smoother and more stable unit operation.
When the tower and pump are both roof mounted, be sure to provide the necessary net positive
suction head pressure to prevent cavitation. Raise the tower or submerge the pump in a sump to
provide positive suction. To prevent an on-line pump failure, use a standby pump to avoid a
complete system shutdown.
Several partial capacity pumps or variable speed pumps may be used. Review the economics of
these alternate pumping options.
Strainers and Water Treatment
Water strainers are required at the unit inlet to eliminate potential unit damage from dirty water.
Specify a water basket-type strainer to avoid an incorrect stream strainer application. Untreated or
poorly treated water may result in equipment damage. Consult a water treatment specialist for
treatment recommendations.
Isolation Valves
Install isolation valves at each unit before the strainer and after the condenser. This allows periodic
servicing of the unit or strainer while allowing other units in the system to remain in operation.
Pressure Gauges
Install pressure gauges on the inlet and outlet of the self-contained unit. Select the gauge’s scale
so that the unit design operating point is approximately mid-scale.
Thermometers
Install thermometers on the condenser water inlet and outlet lines to each unit for system analysis.
Trane Company recommends using a thermometer temperature range of 40 to 140°F, using a 2°F
temperature increment.
Drains
The unit condensate drain is internally trapped to offset the pressure differential that exists during
fan operation. Install a trapped drain in the low point of the mechanical equipment room floor to
collect water from cleaning operations.
Condensing Pressure Control (Water-Cooled condensers)
Often cold condensing water applications between 35°F and 54°F require a condensing pressure
control valve. Any unit with variable-flow waterside valves can modulate water flow to maintain
a user defined condensing temperature. However, to utilize this feature, the building water system
must be capable of operating at reduced water flow rates through the self-contained units. It is
imperative to install variable volume pumps or an external bypass in the water distribution system.
PKG-PRC002U-EN 13
Application Considerations
Free Cooling Opportunities and Alternatives
Free cooling is available with either the airside or waterside economizer options.
Waterside Economizer
The waterside economizer substantially reduces the compressor energy requirements because it
uses the cooling water before it enters the condensers. Additional equipment room space is not
required since the coils are contained within the overall unit dimensions.
Disadvantages include higher airside pressure drop and a higher head on condenser water pumps.
The coils may be mechanically cleanable (optional) for ease in maintenance versus expensive and
difficult chemical cleaning methods.
Airside Economizer
The airside economizer substantially reduces compressor, cooling tower, and condenser water
pump energy requirements using outside air for free cooling. It also reduces tower make up water
needs and related water treatment.
Disadvantages include building requirements that locate the mechanical room and self-contained
unit toward an exterior wall to minimize ductwork, building barometric control, or additional air
shafts. Also, airside economizers require additional mechanical room space.
Unit Operating Limits
Airflow
The minimum recommended airflow for proper VAV system staging and temperature control is 35
percent of nominal design airflow. Adjusting VAV boxes with the appropriate minimum settings
will prevent the self-contained unit from operating in a surge condition at airflows below this point.
Continuous operation in a surge condition can cause fan failure. Reference General Data Tables on
Table 1, p. 20 for minimum airflow conditions.
Waterside Economizer Flow
Control
Units equipped with waterside
economizer control valves can be set
up for variable or constant water flow.
Use constant water flow setup on
water systems that are not capable of
unloading water supply to the unit.
The economizer and condenser
valves will operate in complement to
one another to provide continuous
water flow.
Use variable water flow setup with
water flow systems that can take
advantage of pump unloading for
energy savings. Since non-cooling
operation restricts water flow during
part load economizing or condensing
temperature control, it is imperative
to install variable volume pumps or an
external bypass in the water
distribution system.
14 PKG-PRC002U-EN
Application Considerations
Signature Series self-contained units use fixed pitch sheaves. Adjust air balancing by obtaining
alternate fixed pitch sheave selections from the local Trane sales office.
Water Flow
Use 3 gpm/ton for optimum unit capacity and efficiency. Use 2.5 or 2 gpm/ton to reduce pump
energy, cooling tower and piping costs. However, these reduced water flows may impact unit
capacity and efficiency by one or two percent. Consult General Data Tables on pages 17-20 for unit
specific water flow ranges.
Remote Air-Cooled Condenser
Unit Location
Unobstructed condenser airflow is essential to maintaining capacity and operating efficiency.
When determining unit placement, give careful consideration to assure sufficient airflow across the
condenser coils. Avoid these two detrimental conditions: warm air recirculation and coil starvation.
Both warm air recirculation and coil starvation cause reductions in unit efficiency and capacity
because of the higher head pressure associated with them. In more severe cases, nuisance unit
shutdowns will result from excessive head pressures.
Clearance
Ensure vertical condenser air discharge is unobstructed. While it is difficult to predict the degree
of warm air recirculation, a unit installed with a ceiling or other obstruction above it will experience
a capacity reduction that will reduce the maximum ambient operation limit. Nuisance high head
pressure trips may also occur.
The coil inlet must also be unobstructed. A unit installed closer than the minimum recommended
distance to a wall or other vertical riser will experience a combination of coil starvation and warm
air recirculation. This may result in unit capacity and efficiency reductions, as well as possible
excessive head pressures. Reference the service clearance section on page 111 for recommended
lateral distances.
Ambient Limitations
Standard ambient control allows operation down to 45°F with cycling of condenser fans. Units with
the low ambient option are capable of starting and operating in ambient temperatures down to 0°F.
Optional low ambient units use a condenser fan damper arrangement that controls condenser
capacity by modulating damper airflow in response to saturated condenser temperature.
Maximum ambient operating temperature of a standard condenser is 115°F. Operation at design
ambient above 115°F can result in excessive head pressures. For applications above 115°F, contact
the local Trane sales office.
PKG-PRC002U-EN 15
Selection Procedure
Following is a sample selection for a standard applied water-cooled self-contained at particular
operating conditions. Use Trane Official Product Selection System, TOPSS™, for making all final
selections or contact your local Trane representative.
Unit Capacities
1. Determine entering air temperature dry bulb and wet bulb and entering water temperature.
2. See chapter “Performance Data,” p. 27 to find gross total and sensible capacity that best meets
capacity requirements.
3. Apply the cfm correction factors from the capacity correction factor Ta b l e 13, p. 37 to determine
gross total and gross sensible capacities at desired cfm.
4. Multiply condenser water delta T by the total capacity cfm correction factor to determine new
condenser water delta T.
5. Using design cfm, determine static air pressure drops for accessories from the air pressure
drop Charts Figure 1, p. 27 through Figure 21, p. 33. Add accessory static pressure drops to
external supply and return static air pressure drops. Use the total air pressure drop to determine
rpm and brake horsepower requirements from the appropriate fan curve. Note: The fan curves
include refrigerant coil and internal cabinet static loses.
6. Calculate supply fan motor heat by using the following equation:
Fan motor heat (MBh) = 2.8 x fan motor brake horsepower
7. Determine net total capacity and net sensible capacity by subtracting fan motor heat from gross
total capacity and gross sensible capacity.
8. Refer to Trane psychometric chart to determine leaving air temperatures.
Waterside Economizer Capacity
After determining that the unit will meet the required mechanical cooling capacity, determine the
waterside economizer capacity by referring to the appropriate two-row (low capacity) or four-row
(high capacity) waterside economizer capacity found in one of Table 15, p. 38 through Ta b l e 48 ,
p. 72.
9. Determine entering air temperature dry bulb and wet bulb, condenser water flow (gpm), and
economizer entering water temperature.
10. Refer to the appropriate waterside economizer table to find gross total and sensible capacity
and the leaving water temperature.
11. Apply the cfm correction factor for the waterside economizer from the appropriate table to
determine the gross total and sensible capacities at the desired cfm.
12. Multiply the condenser water delta T by the total capacity cfm correction factor to determine
the new delta T.
13. Calculate supply fan motor heat by using the following equation:
Fan motor heat (MBh) = 2.8 x fan motor brake horsepower
14. Determine net total and sensible capacity by subtracting fan motor heat from gross total and
sensible capacity.
15. Refer to the Trane psychometric chart to determine leaving air temperatures.
Selection Example
Design Conditions
Total gross capacity required = 420 MBh = 35.2 Tons
Total sensible capacity required = 315 MBh
Entering air temperature = 80/67°F
16 PKG-PRC002U-EN
Selection Procedure
Entering water temperature = 85°F
Water flow rate = 105 gpm
Airflow = 14840 cfm at 2.5-inch duct static pressure
Unit includes:
•Constant Volume
•Waterside economizer
•Medium velocity throwaway filters
Unit Selection
Tentatively select a 35 ton unit: Model SCWF 35.
Refer to Table 26, p. 49 to obtain gross total and sensible unit capacities, and gpm at the design
conditions:
Total capacity = 432.0 MBh
Sensible capacity = 329.0 MBh
Leaving water temperature = 95.1°F
Since the design cfm is greater than the nominal cfm, adjust the capacities and condenser water
delta T to reflect the higher cfm: design cfm 14840 = +6% of nom. Cfm nominal 14000 cfm
Refer to Tab l e 13 , p . 3 7 to obtain the capacity correction factors for +6% of nominal cfm:
Cooling capacity multiplier = 1.009
Sensible capacity multiplier = 1.027
Multiply the capacities by the correction factors:
•432 MBh x 1.009 = 435.89 MBh
•329 MBh x 1.027 = 337.88 MBh
The SCWF 35 meets the total and sensible design requirements.
Multiply the delta T of 10.1°F by the cooling capacity correction factor of 1.009 to obtain new delta
T of 10.19°F and add this to the entering water temperature to obtain the actual leaving water
temperature of 95.19°F.

Airside Pressure Drops
The dotted line on construction filters indicates cfm where face velocity exceeds manufacturer’s
recommended maximum of 300 fpm. After startup, construction filters must be replaced with
medium velocity or high velocity filters.
Air pressure drops through electric heat is 0.5 inches WC.
See “Discharge Plenum,” p. 30 for pressure drop through flexible horizontal discharge plenum and
“Heating Coils,” p. 29 for pressure drop through heating coils.
For 4-inch cartridge filters, air pressure drops must be added to the external static pressure design
point.

Controls
IntelliPak™ Signature Series Self-Contained Units
We’ve redesigned the self-contained unit with the latest control technology to make it even better!
New modular DDC controls with human interface (HI) panel make self-contained units more
flexible and easier to operate.
Controls are Trane-designed to work with Trane equipment for optimum efficiency. The factory
installs and commissions each control component to ensure simple and reliable operation.
Furthermore, the DDC control’s modular design allows greater application flexibility using up to
twelve different modules, dependent upon unit options. You can order exactly what the job
requires as options, instead of one large control package. And since unit features are distributed
among multiple printed circuit boards, field replacement is easy.
Depending upon unit options, IntelliPak® units can operate as:
1. stand-alone
2. interface with Trane’s Tracer® building management system
3. interface with a generic (non-Trane) building management system.

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

The BACnet Communication Interface for IntelliPak self-contained (BCI-I) controller expands
communications from the unit UCM network to Tracer SC or a 3rd party building automation
system, utilizing BACnet, and allows external setpoint and configuration adjustment and
monitoring of status and diagnostics. The BCI-I utilizes the BACnet defined MS/TP protocol as
defined in ASHRAE standard135-2004. This controller works in standalone mode, with Tracer SC
or when connected to a 3rdparty building automation system that supports BACnet.

Standard IntelliPak Unit Control Features
All set-up parameters are preset from the factory, requiring less start-up time during installation.
The human interface panel is easy to read and requires less time for building maintenance
personnel to learn to interact with the unit. It features a clear language display (in English, Spanish,
or French) that shows all of the self-contained unit control parameters, such as system on/off;
demand limiting type; night setback setpoints; and many other setpoints. All adjustments are done
through the human interface key-pad. Also the human interface panel allows you to monitor
diagnostic points such as; sensor failures; supply airflow loss; and inoperative refrigerant circuit.
No special tools are required for servicing the unit. Diagnostics are held in memory, even during
power loss. This allows the operator/servicer to diagnose the failure root cause.

Control Sequences of Operation
Morning Warmup
This feature is available on all types of factory-installed heat units and on units with no heat. This
function may still be selected to support systems with heat sources not provided by the self-
contained unit. At the conclusion of unoccupied mode, the selected zone is heated to the user-
defined morning warmup setpoint. The unit is then released to occupied mode. There are two types
of morning warmup: full capacity or cycling capacity.
Full Capacity Morning Warmup (MWU). Full capacity morning warmup uses full heating
capacity to heat the zone as quickly as possible. Full heating capacity is provided until the morning
warmup setpoint is met. At this point, the unit is released to daytime mode.
Cycling Capacity Morning Warmup (MWU). Cycling capacity morning warmup provides
gradual heating to overcome “building sink” as the zone is heated. Normal zone temperature
control with varying capacity is used to raise the zone temperature to the MWU zone temperature
setpoint. Cycling capacity MWU will operate until MWU setpoint is reached or for 60 minutes. Then
the unit switches to occupied mode. Cooling will suspend untill building load conditions exceed
the MWU setpoint of 3 F (1.7 C), which is field adjustable.
Note: When using the morning warmup option in a heating/cooling self-contained unit in a VAV
system, it is important to maintain airflow through the unit. This can be accomplished by
electrically tying the VAV boxes to the VAV drive max output relay contacts on the unit’s RTM
module board or by using changeover thermostats. Either of these methods will assure
adequate airflow through the unit and satisfactory heating.
Ventilation Override (VOM) Option
The user can customize up to five different override sequences for purposes of ventilation override
control. If more than one VOM sequence is being requested, the sequence with the highest priority
is initiated first. Priority schedule is that sequence “A” (unit off) is first, with sequence “E” (purge
with duct pressure control) last.

UNIT OFF sequence “A”. When complete system shut down is required, the following sequence
can be used.
• Supply fan – Off
• Supply fan VFD – Off (0 Hz) (if equipped)
• Outside air dampers – Closed
• Heat – all stages – Off, Modulating heat output at 0 vdc
• Occupied/Unoccupied output – Deenergized
• VO relay – Energized
• Exhaust fan (field-installed) - Off

the conditioned space becomes negatively pressurized. This is desirable for clearing the area of
smoke when necessary; i.e. from an extinguished fire, to keep smoke out of areas that were not
damaged.
• Supply fan – Off

coming out of unoccupied mode of operation on VAV units. Also, it can be used to purge smoke
or stale air.
• Supply fan – On
• Supply fan VFD – On (60 Hz)\VAV boxes – Open (if equipped)
• Outside air damper – Open
• Heat – all stages – Off, Modulating heat output at 0 vdc

Note: Each system (cooling, exhaust, supply air, etc.) within the unit can be redefined in the field
for each of the five sequences, if required. Also the definitions of any or all of the five
sequences may be locked into the software by simple key strokes at the human interface
panel.
Generic Building Automation System Module (GBAS) Option
The generic building automation system module (GBAS) provides broad control capabilities for
building automation systems other than Trane’s Tracer® system. A field provided potentiometer
or a 0-5 vdc signal can be applied to any of the inputs of the GBAS to provide the following inputs
and outputs.
GBAS Analog Inputs . Four analog inputs that can be configured to be any of the following:
1. Occupied zone cooling
2. Unoccupied zone cooling
3. Occupied zone heating
4. Unoccupied zone heating
5. SA cooling setpoint
6. SA heating setpoint
7. Space static pressure setpoint
8. SA static pressure setpoint
GBAS Binary Outputs . Each of the five (5) relay outputs can be mapped to any/all of the
available diagnostics.
Demand Limiting Binary Input . This function is operational on units with a GBAS and is used
to reduce electrical consumption at peak load times. There are two types of demand limiting, 50%
and 100%. When demand limiting is needed, mechanical cooling and heating operation are either
partially (50%), or completely disabled (100%) to save energy. The demand limit definition is user
definable at the human interface panel. Demand limit binary input accepts a field supplied switch
or contact closure. When the need for demand limiting has been discontinued, the unit’s cooling/
heating functions will again become fully enabled.
Evaporator Coil Frost Protection FROSTAT™
A temperature sensor on the evaporator is used to determine if the coil is getting close to a freezing
condition. Mechanical cooling capacity is shed as necessary to prevent icing.
The FROSTAT™ system eliminates the need for hot gas bypass and adds a suction line surface
temperature sensor mounted near the TXV bulb location to shut off the cooling when coil frosting

compressors from rapid cycling.
Occupied/Unoccupied Switching
There are four ways to switch occupied/unoccupied:
1. Programmable night setback sensor
2. Field-supplied contact closure (hardwired binary input to RTM)
3. Tracer®
4. Factory-mounted time clock
Field Supplied Occupied/Unoccupied input on the RTM. This input accepts a field
supplied switch or contacts closure such as a time clock.
Trane Tracer® System. The Trane Tracer® system can control the occupied/unoccupied status
of the self-contained unit.
Factory Mounted Time Clock. A time clock can control the occupied/unoccupied status of the
self-contained unit.
Timed Override Activation - ICS
This function is operational whenever the unit’s RTM module board is used as the zone temperature
sensor source, which can be set at the human interface panel. When this function is initiated by the
push of the override button on the zone sensor, the unit will switch to the occupied mode. Unit
operation (occupied mode) during timed override is terminated by a signal from Tracer.
Timed Override Activation - Non-ICS
This function is active whenever the unit’s RTM module board is selected as the zone temperature
source, which can be set at the human interface panel. When this function is initiated by the push
of the override button on the zone sensor, the unit will switch to the occupied mode. Automatic
cancellation of the timed override mode occurs after three hours of operation.
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 when using a field-installed outside air sensor. This
setpoint is adjustable at the human interface panel. Compressors will lock out when outdoor air
temperature falls below that selected temperature and will start again when the temperature rises
5° F above the setpoint.
Comparative Enthalpy Control of Airside Economizer Option
An optional comparative enthalpy system is used to control the operation of the economizer and
measures the temperature and humidity of both return air and outside air to determine which
source has lower enthalpy. This system allows true comparison of outdoor air and return air
enthalpy by measurement of outdoor and return air temperatures and humidities.
Note: If comparative enthalpy is not ordered, the standard method compares outdoor air enthalpy
with a fixed reference enthalpy, set through the human interface panel.
Compressor Lead/Lag
Compressor lead/lag is a user-selectable feature through the human interface panel available on
all units. After each request for compressor operation, the lead refrigeration circuit or compressor
switches, thereby causing a more equitable or balanced run time among compressors.
Emergency Stop Input
A binary input is provided on the unit’s RTM module board for installation of a field-provided switch
or contacts to immediatly shutdown all unit functions.

Controls
Water Flow Control
With compatible piping configurations, the unit can be configured to provide:
1) Constant water flow with basic or intermediate piping or 2) Variable water flow with intermediate
piping only.
Constant water flow is for condenser pumping systems that are not capable of unloading the water-
pumping system. Variable water flow maximizes energy saving by unloading the water pumping
system.
Head Pressure Control
Water-Cooled Condensers. Units that are set up for variable water flow will modulate a water
valve to maintain a user-defined condensing temperature setpoint. Condensing temperature will
be referenced utilizing factory installed sensors located at each condenser.
Air-Cooled Condensers. Condenser fans will stage per a user-defined setting. If the condenser
is equipped with head pressure control (air modulation on last stage of condenser capacity), the
condenser airflow will modulate to maintain condensing temperature setpoint. Condensing
temperature is determined by sensors located at each condenser coil.
Water Purge
This user-definable feature allows the user to select a purge schedule to automatically circulate
water through the economizer and condensers periodically during non-operational times. This
allows fresh chemicals to circulate in waterside heat exchangers.
Airside Options
Variable Frequency Drive (VFD) Control
Variable frequency drives are driven by a modulating 0-10 vdc signal from the RTM module. A
pressure transducer measures duct static pressure, and the VFD adjusts the fan speed 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.
Variable frequency drives provide supply fan motor speed modulation. The drives will accelerate
or decelerate as required to maintain the supply static pressure setpoint.
Bypass control is offered as an option to provide full nominal airflow in the event of drive failure.
Manual bypass is initiated at the human interface panel. When in the bypass mode, VAV boxes will
need to be fully opened. The self-contained unit will control heating and cooling functions to
maintain setpoint from a user defined zone sensor. Supply air static pressure limit will be active
in this mode.
Supply Air Static Pressure Limit
The opening of the VAV boxes are coordinated during unit start up and transition to/from occupied/
unoccupied modes to prevent overpressurization 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/VFD is shut down. Then unit will attempt to restart,
up to three times. If the overpresssurization condition still occurs on the third restart, the unit shuts
down and a manual reset diagnostic sets and displays at the human interface panel.

Zone Temperature Control Unit Sequence Of Operation
1
Occupied Zone Temperature Control
Cooling/Waterside Economizer
During occupied cooling mode, the waterside economizer option and mechanical cooling function
to control zone temperature. If the entering condenser water temperature is appropriate to use
“free cooling,” the economizer initiates to attempt to satisfy the cooling zone temperature setpoint
with the compressors staging on as necessary. Minimum on/off timing of compressors prevents
rapid cycling.
Waterside economizing enables when the unit’s entering water temperature is below the unit’s
entering mixed air temperature by 4°F plus the user adjustable economizer approach temperature.
The approach temperature default is 4°F and is adjustable from 0-9°F at the human interface (HI)
panel. Waterside economizing disables when the unit’s entering water temperature is not below
the unit’s entering mixed air temperature by at least the water economizer approach temperature.
The approach temperature defaults to 4°F and is adjustable from 0-9°F at the HI. The economizer
acts as the first stage of cooling. If the economizer is unable to maintain the zone temperature
setpoint, the compressor module will bring on compressors as required to meet the setpoint.
If the unit does not include an economizer, only mechanical cooling will operate to satisfy cooling
requirements.
Cooling/Airside Economizer
During occupied cooling mode, the economizer option and mechanical cooling operate to control
zone temperature. If the outside air enthalpy is appropriate for airside economizing or “free
cooling,” the economizer initiates to satisfy the cooling zone temperature setpoint with the
compressors staging on as necessary. Minimum on/off timing of compressors will prevent rapid
cycling.
On units with an airside economizer, a call for cooling will modulate the fresh 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 fresh air damper will open. First stage of cooling
will start after the economizer reaches full open.
Note that the airside economizer will only function freely if ambient conditions are below the
enthalpy control settings or below the return air enthalpy if unit has comparative enthalpy installed.
If outside air is not suitable for “economizing,” the fresh air dampers drive to the minimum open
position. A field adjustable, factory default setting in the human interface panel or Tracer can
provide the input to establish the minimum damper position.
At outdoor air conditions above the enthalpy control setting, only mechanical cooling is used and
the fresh air dampers remain at minimum position.
If the unit does not include an airside economizer, only mechanical cooling will operate to satisfy
cooling requirements.
Heating: Electric
On units with electric heating, the zone temperature can be controlled to a heating setpoint during
the occupied mode by cycling a single stage electric heater. Interface is provided for field supplied
single stage electric heat. The zone temperature heating setpoint and deadband are user defined
at the human interface panel.
Heating: Hot Water or Steam
On units with hot water or steam heating, the zone temperature can be controlled to a heating
setpoint during the occupied mode. The zone temperature heating setpoint and deadband are user
defined at the human interface panel.

Supply Air Tempering
For hot water, steam, or electric heat units in the heat 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 unit transitions out of
heat mode if the supply air temperature rises to 10°F above the occupied zone heating temperature
setpoint.
Auto Changeover
When the system mode is auto, the mode will change to cooling or heating as necessary to satisfy
the zone cooling and heating setpoints. The zone cooling and heating setpoints can be as close as
2°F apart.

Unoccupied Zone Temperature Control
Cooling and Heating
Both cooling and heating modes can be selected to maintain unoccupied zone temperature
deadbands. For unoccupied periods, heating, economizer operation, or compressor operation can
be selectively locked out at the human interface panel.

During occupied cooling mode of operation, the airside economizer option 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. If the temperature of the mixed air is appropriate to
use “free cooling,” the economizer initiates to satisfy the supply air setpoint. Then if required, the
mechanical cooling stages on to maintain supply air temperature setpoint. Minimum on/off timing
of the mechanical cooling prevents rapid cycling.
On units with an airside economizer, a call for cooling will modulate the fresh air dampers open.
The rate of economizer modulation is based on deviation of the discharge temperature from
setpoint, i.e., the further away from setpoint, the faster the fresh air damper will open. First stage
of cooling initiates after the economizer reaches full open.
Note that the airside economizer is only allowed to function freely if ambient conditions are below
the setpoint control settings or below the return air enthalpy, if unit has the comparative enthalpy
option. If outside air is not suitable for “economizing,” the fresh air dampers drive to the minimum

open position. A field adjustable, factory default setting in the human interface panel or Tracer can
provide the input to establish the minimum damper position.
At outdoor air conditions above the setpoint or comparative enthalpy control setting, only
mechanical cooling is used and the fresh air dampers remain at minimum position.
If the unit does not include an economizer, only mechanical cooling operates to satisfy cooling
requirements.
Heating: 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 initiated by closing a field-supplied switch or contacts connected to a changeover input on the
unit’s RTM module board .
Supply Air Setpoint Reset
Supply air reset can be used to adjust the supply air temperature setpoint on the basis of a zone
temperature or outdoor air temperature. Supply air reset adjustment is available from the human
interface panel for supply air heating and supply air cooling control.
Reset based on outdoor air temperature
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
• Maximum amount of temperature reset
Reset based on zone temperature
Zone reset is applied to the zone(s) in a building that tends to overcool 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.
Supply Air Tempering (Hot Water and Steam Units Only)
When supply air temperature falls below the supply air temperature deadband low end, the heating
valve modulates open to maintain the minimum supply air temperature setpoint.

Unoccupied Supply Air Temperature Control, Zone Heating, Cooling
During unoccupied mode, the unit operates to maintain zone temperature with fan cycling as
needed for building load. VAV boxes drive full open. However, unit airflow modulation control
operates to maintain duct static setpoint. The unit controls zone temperature within the unoccupied
zone cooling and heating (heating units only) deadbands.
Daytime Warmup
During occupied mode, if the zone temperature falls to a preset, user-defined zone low limit
temperature setpoint, the unit is put into daytime warmup. The system changes over to CV heating,

A Check Filter Timer function is included. Filter service countdown time can be
set in one-day increments. Activation of the Test/Configuration button located
on the bottom of the sensor performs a sensor self-diagnostic routine and
indicates hours in service.
When the BAYSENS119 is programmed for CV or VAV control, Night Setback is
initiated through the scheduled Unoccupied time setting. When the sensor
switches to Night Setback, the outdoor dampers close and heating/cooling
functions are enabled/disabled based on set up parameters. As building load
changes, if heating/cooling functions are enabled, the Sensor energizes self-
contained unit and evaporator fan operation. The unit will cycle heating/cooling
operation throughout the Unoccupied period as required to maintain
Unoccupied space temperature setpoints. When the Unoccupied time period
has expired, all heating/cooling functions return to normal operation.
When Night Setback options are used with VAV heating/cooling, maintain
airflow through the self-contained unit by electronically tying the VAV terminals
to the unoccupied output relay contacts on the self-contained units low voltage
terminal board, or by using changeover thermostats. Either of these methods

circuit: 1) fans and 2) compressors.
If the rating value calulation does not equal a standard over current protective device rating, use
the next lower standard rating as the maximum.

Economizer
The waterside economizer takes advantage of cooling tower water to either pre-cool the entering
air to aid the mechanical cooling process or, provides total system cooling if the water temperature
is low enough. Waterside economizing enables when the unit’s entering water temperature is
below the unit’s entering mixed air temperature by a minimum of 4°F plus the economizer’s
approach temperature. The approach temperature default is 4°F and is adjustable from 0 to 9°F.
Waterside economizing disables when the unit’s entering water temperature is not below the unit’s
entering mixed air temperature by at least the water economizer approach temperature. The
economizer acts as the first stage of cooling. If the economizer is unable to maintain the supply air
setpoint, the unit control module brings on compressors as required to meet the setpoint.
The waterside economizer includes a coil, modulating valves, controls, and piping with cleanouts.
All components are factory installed in the unit cabinet. The coil construction is ½-inch (13mm) OD

working pressure is rated for 400 psig (2758 kPa).
PKG-PRC002U-EN 121
Mechanical Specifications
Airside Economizer
Units with the airside economizer option are equipped with the necessary control sequences to use
outside air for the first stage of cooling, in occupied or unoccupied mode and when ambient
conditions are favorable for economizing. Inherent in the unit controller is the ability to suppress
the setpoint below the normal unit setpoint. This allows the building to improve comfort levels
when possible, and at the same time, optimize building mechanical cooling operation for peak
operating efficiency. An outside air temperature and relative humidity sensor are provided to allow
monitoring of reference enthalpy and are field installed. Economizer operation enables when the
outside air enthalpy is less than 25 BTU’s/lb. default (adjustable 19-28 BTU’s/lb.). During occupied
mode, the outside air damper opens to 15% (adjustable 0-100%) for ventilation purposes. Also, the
ability to alter the outside air damper position to compensate for VAV supply air modulation is
inherent in the unit controls, and can be enabled by the operator.
The mixing box fabrication is sturdy-gauge galvanized steel. Opposed low leak damper blades are
fabricated from sturdy-gauge galvanized steel and rotate on rustproof nylon bushings. A factory
installed 24V modulating spring return actuator controls both damper positions.
Comparative Enthalpy Control
Units with comparative enthalpy control are equipped with the necessary control sequences to
allow using outside air for the first stage of cooling, in occupied or unoccupied mode and when
ambient conditions are favorable for economizing. Inherent in the unit controller is the ability to
suppress the setpoint below the normal unit setpoint. This allows the building to improve comfort
levels when possible, and at the same time, optimize building mechanical cooling operation for
peak operating efficiency. A factory-installed control board, with field-installed outside and return
air temperature and relative humidity sensors, allows monitoring of outside and return air.
Economizer operation enables when the outside air enthalpy is 3 BTU’s/lb. less than the return air
enthalpy. During occupied mode, the outside air damper opens to 15% (adjustable 0-100%) for
ventilation purposes. Also, the ability to alter the outside air damper position to compensate for
VAV supply air modulation is inherent in the unit controls, and can be enabled by the operator.
The mixing box fabrication is sturdy-gauge galvanized steel. Opposed low leak damper blades are
fabricated from sturdy-gauge galvanized steel and rotate on rustproof nylon bushings. A factory
installed 24V modulating spring return actuator controls both damper positions.
Standard Two-Position Damper Interface
Units with the two-position damper interface are provided with a 0-10 VDC control output suitable
for controlling a field-provided modulating actuator. In occupied mode, the output drives to the
maximum position.
Airside Economizer Interface
Units with airside economizer interface are equipped with the necessary control sequences to
allow using outside air for the first stage of cooling, in occupied or unoccupied mode and when
ambient conditions are favorable for economizing. Inherent in the unit controller is the ability to
suppress the setpoint below the normal unit setpoint. This allows the building to improve comfort
levels when possible, and at the same time, optimize building mechanical cooling operation for
peak operating efficiency. An outside air temperature and relative humidity sensor are provided for
field installation to monitor reference enthalpy. Economizer operation enables when the outside
air enthalpy is less than 25 BTU’s/lb. (adjustable 19-28 BTU’s/lb). During occupied mode, the outside
air damper opens to 15% (adjustable 0-100%) for ventilation purposes. Also, the ability to alter the
outside air damper position to compensate for VAV supply air modulation is inherent in the unit
controls, and can be enabled by the operator. An analog 2-10 VDC output (adjustable (0-10 VDC)
is provided to modulate the field-provided 30 second damper actuators (adjustable 1-255 seconds).

mode and when ambient conditions are favorable for economizing. Inherent in the unit controller
is the ability to suppress the setpoint below the normal unit setpoint. This allows the building to
improve comfort levels when possible, and at the same time, optimize building mechanical cooling
operation for peak operating efficiency. A factory-installed control board, with outside and return
air temperature and relative humidity sensors, are provided for monitoring outside and return air.
The sensors are field installed. Economizer operation enables when the outside air enthalpy is 3
BTU’s/lb. less than the return air enthalpy. During occupied mode, the outside air damper opens
to 15% (adjustable 0-100%) for ventilation purposes. Also, the ability to alter the outside air damper
position to compensate for VAV supply air modulation is inherent in the unit controls, and can be

the field-provided 30-second damper actuators (adjustable 1-255 seconds).
Basic Water Piping
This option is available on units without a waterside economizer and with condenser water
applications above 54°F that do not require condensing pressure control. Left hand water
connections and piping are extended to the unit exterior. Manifold piping is factory installed.
Intermediate Water Piping
This option provides condensing temperature control when the unit is configured (user defined at
the HI) for variable water flow with or without a waterside economizer. A two-way modulating
control valve is wired and installed in the unit to maintain a specific range of water temperature
rise through the condenser when entering fluid temperature is less than 58°F. This option allows
the compressor to operate with entering fluid temperature down to 35°F.
Waterside Economizer Flow Control
Units equipped with a waterside economizer can be set from the human interface panel for variable
or constant water flow.
Constant Water Flow
Two-way modulating control shutoff valves are wired, controlled, and installed in the unit. One
valve is located in the economizer’s water inlet, and the other is in the condenser bypass water inlet.
When the waterside economizer enables, the two-way valve modulates to maintain the discharge
air temperature setpoint. As the economizer valve opens, the condenser bypass valve closes, and
vice versa. Full water flow is always maintained through the condensers. Both valves will close in
the event of a power failure.
Variable Water Flow
Two-way modulating control shutoff valves are wired, controlled, and installed in the unit. One
valve is located in the economizer’s water inlet, and the other is in the condenser bypass water inlet.
When the economizer valve is active, the condenser bypass valve closes. The economizer valve
modulates, thus water flow through the unit modulates. If the water is cool enough for
economizing, but mechanical cooling is also required, the economizer valve fully opens to establish
full water flow through the condensers. Whenever the water is too warm for economizing and there
is a call for cooling, the economizer valve fully closes and the bypass valve fully opens, establishing
full water flow through the condensers. Full water flow is always maintained through the
condensers when mechanical cooling is required. Both valves close whenever cooling is not
required and in the event of a power failure.
Water Flow Switch
A water flow switch is factory installed in the condenser water pipe within the unit. Whenever the
flow switch detects a water flow loss prior to or during mechanical cooling, compressor operation
locks out and a diagnostic code displays. If water flow is restored, the compressor operation
automatically restores.
