Features and Benefits
The Force-Flo cabinet heater meets the standards of today’s market, as well as the anticipated
needs of tomorrow’s market. The tradition that company founder Reuben Trane began in 1913
continues with the latest generation of cabinet heaters from Trane.
The Force-Flo cabinet heater is the leader in these key areas:
• Energy Efficiency
• Indoor Air Quality (IAQ)
• Controls
•Flexibility
•Quality
• Serviceability
Today’s HVAC market is concerned with issues such as indoor air quality (IAQ) and CFCs that
demand a change in HVAC products. In addition, renovation has overtaken new construction in the
cabinet heater market - demanding a design that caters to renovation issues. Trane is concerned
with these issues, too. That’s why we designed the Force-Flo cabinet heater as an integral part of
the company’s system solutions with standard IAQ-related features that comply with ASHRAE 62.
Energy Efficiency
Trane’s commitment to providing premium quality products has led to the exclusive use of
Electronically Commutated Motors (ECM) in all fan coil models. These brushless DC motors
incorporate the latest technology for optimized energy efficiency, acoustical abatement,
maintenance free and extended motor life. Each motor has a built-in microprocessor that allows
for programmability, soft ramp-up, better airflow control, and serial communication.
• Trane units equipped with ECMs are significantly more efficient than the standard Permanent
Split Capacitor (PSC) motor.
• Lower operating costs on average of 50 percent (versus a PSC motor).
• The Reduced FLA feature allows units to ship with a nameplate FLA rating much lower than a
typical ECM unit.
IAQ Design
• Closed-cell insulation is standard on all units to help prevent fiberglass in the airstream.
• Easy filter access encourages frequent changing.
• Force-Flo cabinet heaters have a blow-thru design.
Controls
• This is the industry’s first solution that is factory mounted, wired and programmed for infinite
modulation of fan speed based on space loads, using the UC400.
• Auto Fan Speed control with the Tracer ZN520 ramps the fan speed up and down to meet space
loads.
• All controls are factory-mounted and tested to minimize field setup and improve reliability.
• Controls are wired with a 24 Vac transformer to keep only a single source power connection
requirement to the unit.
• All wall-mounted zone sensors require only low voltage control wiring from the device to the
unit control box. (No line voltage.)
• The random startup feature helps reduce electrical demand peaks by randomly staggering
multiple units at startup.
• Occupied/unoccupied operation allows the controller to utilize unoccupied temperature
setpoints for energy savings.

Features and Benefits
• Warm-up energy feature is standard with Trane controls.
• Continuous fan or fan cycling is available with Tracer ZN010 or ZN510.
• Monitor unit operation using Tracer SC building management system with Tracer ZN510.
• To customize unit control, Tracer TU or Rover™ software will allow field modification of Tracer
ZN510, ZN520 and UC400 default settings.
• Maximize cabinet heater system efficiency with modulating valves on units with Tracer ZN520
and UC400.
Flexibility
• Two-, three-, and four row hot water coils allow greater design flexibility. Steam distributing or
electric heat coils are also available.
• Fan motors are available for either high static (0.4-inch external static pressure) or free
discharge applications.
• Piping is factory-assembled, -mounted, and -tested. Units are also available without piping.
• Factory piping options include interconnecting piping, control valves, and end valves. Deluxe
piping also has unions and a strainer.
• Control options range from a simple fan speed switch to a DDC controller that can tie into a
Tracer SC building automation system.
• The extended end pocket option adds 8 inches (20 cm) to the piping end of cabinet style units.
• Slope-top vertical cabinet units are an excellent application for school and dormitories to
prevent items from being placed on top of the units.
• Vertical wall hung units are used in vestibules, bathrooms, stairwells, or other applications
when the unit cannot be installed on the floor.
• Inverted unit models allow heating to circulate from the bottom of the unit.
Quality
• Coils and piping packages are air and leak-tested before mounting on the unit.
• Coil piping connections are also air and leak-tested after mounting on the unit.
• All control end devices and moving components (fans and motors) are computer-tested after
units are complete.
Serviceability
• Touch-safe control box.
• Integrated user interface with real language LED display.
• Built-in tachometer.
• Filters are easily removable and changed without removing the front panel on vertical cabinet
units.
• Motors are easy to disconnect from the fan board, allowing easy service.
• The manual output test function is an invaluable troubleshooting tool. By simply pressing the
test button on the Tracer ZN510, ZN520, or ZN010; service personnel can manually exercise
outputs in a pre-defined sequence.

General Data
Electric Heat
All Force-Flo cabinet heaters, except inverted models M and N, are available with electric heating
coils as a standard option.
Coil Construction
Electric heat coils are open wire type with a nickel chromium element design.
Power Supply
Units have single-point power since the electric heating elements operate on line voltage. Electric
heat is available as 208/60/1, 230/60/1, 277/60/1, 208/60/3, or 480/60/3. Electric heat coils operate on
the same voltage as the unit, except for units with 480/60/3 electric heat. In this case, the unit
operates at 277/60/1, thus requiring a 4-wire supply. All fans and motors are single phase. In
addition, all control options are 24-volt, utilizing a factory-installed transformer.
Power Supply Location
All electric heat cabinet heaters have a terminal block for main power on the unit’s right-hand side.
Control Type
Single-stage electric heat units are controlled by either Tracer UC400, ZN010, ZN510, or ZN520
control options. Two-stage electric heat is controlled by the Tracer UC400, ZN520 only. Both
control options use PWM (pulse-width modulation) outputs to calculate the electric heat output

General Data
based on the capacity request and the electric heat cycles per hour. For example, if the electric heat
cycles per hour is configured for six cycles (as Trane recommends) the controller bases the output
on or off time on six 10-minute periods. If the capacity request is 40 percent, the controller controls
the electric heat output on for approximately four minutes each period.
Safety Features
• Fan/valve operation to ensure safe operation and to ensure that two modes of heat are not
operating simultaneously.
• All Force-Flo units with standard electric heat are UL listed.
• Units require only a single-point electrical connection.
• All electric heating coils are interlocked with the fan motor switch. Therefore, electric heat
operation is only possible when the fan is running.
• Each unit has a transformer, eliminating the need for field installation of a stepdown
transformer.
• Unit-mounted quiet magnetic relays are supplied on all unit voltages.
• A line-break high temperature cutout with automatic reset is provided as an integral part of the
elements to de-energize the electric heat in the event of an overheat condition.
Factory-Installed Piping Packages
Force-Flo cabinet heaters have standard piping packages available as a factory built and installed
option. Factory built assures all piping packages are fully tested under water for leaks and are built
within strict tolerances. Factory-installed means that supply and return pipes are the only field
connections required. The installer doesn’t have to sweat connect piping packages onto coil
connections in a tight end pocket. Field connections are brought to a point near the exterior of the
unit for easy access.
Piping Package Components
Force-Flo piping packages consist of a variety of components for each application. The following
section provides a detailed description of the piping components. Following this section are
additional illustrations and specifications.
Piping System/Placement
Factory piping packages are available with right or left hand connections. A simple coil connection
(a unit without a piping package) is also available in either a right or left hand configuration for
those applications requiring field piping.
Interconnecting Piping
Interconnecting piping refers to the copper piping that attaches the coil connections and all other
components such as control valves, end valves, etc. Piping is 1/2” nominal OD copper and extends
near the unit exterior to one inlet and one outlet connection.
Deluxe or Basic Piping Package
The basic piping package includes only the main components of the piping package:
interconnecting piping, control valves, and end valves.
The deluxe piping package also includes a strainer on the entering water pipe and unions at the
coil connections along with the basic components listed above. The strainer body is cast brass
construction, with a stainless steel mesh strainer that is easily removed for cleaning. The unions
are forged brass construction and close with a minimum amount of effort.
CAB-PRC001-EN.book Page 17 Tuesday, May 8, 2012 10:11 AM

General Data
End Valves
Each piping package includes a ball valve for the entering water pipe and one of the following end
valves on the leaving water pipe: ball valve, manual circuit setter, or an auto circuit setter. These
valves serve as the field connection points on all Force-Flo piping packages.
Ball Valves
Ball valves, also known as stop or end valves, allow the unit to be cut off for service purposes. These
valves have a two-inch handle that rotates 90° to a fully open position. The valve body is cast brass,
and the ball is polished brass with a Teflon® seat. Ball valves are available as end valves on both
the entering and leaving water pipes.
Manual Circuit Setter
In lieu of a ball valve on the leaving water pipe, a manual circuit setter, also known as a manual flow
control valve, acts as both a flow setting device and a stop valve. This valve allows water flow
through the cabinet heater to be set quickly and accurately.
The manual circuit setter includes Schrader ports in the valve body. These ports are used to
measure the pressure drop across the valve. This pressure drop can be compared to factory
supplied curves that relate the pressure drop to a specific flow rate. This valve also has a memory
stop that helps find the correct setting quickly.
Auto Circuit Setter
An auto circuit setter is an automatic flow control device available on the leaving water pipe. The
auto circuit setter includes a cartridge within the valve body that is sized to allow a specific flow
rate through the coil. This valve sets flow through the coil without any action required by a system
piping balancer. The auto circuit setter is available on the leaving water pipe with a ball valve.
The auto circuit setter also includes two P/T’s plugs in the valve body to allow measurement of the
pressure drop temperature through the valve.
Control Valves
Piping packages are available with or without control valves. All control valve options are factory
mounted and wired to the Force-Flo unit controls.
Tw o - Wa y / Tw o - Po s i t i o n Va l v e s
These valves will either fully open or close in response to a 24 Vac signal from the Tracer controller.
Control valves are direct-acting valves. The control valve is factory mounted in the leaving water
pipe downstream of the coil. Always use some means of relieving pump head pressure with two-
way valve applications. Normally open or normally closed valves are available.
Three-Way/Two-Position Valves
These valves will either allow full water flow through the coil or divert the flow through a bypass
line. The valves respond to a 24 Vac signal from the Tracer controller. Control valves are direct
acting valves. All three-way valve packages include a balance fitting in the bypass line to allow flow
balancing in the bypass position. Three-way valves are factory mounted in the leaving water pipe
downstream of the coil. Normally open or normally closed valves are available.
Two-Way Modulating Valves
These valves modulate the water flow through the coil in response to a signal from the Tracer
controller. Modulating valves are three-wire floating point equal percentage valves, and are factory
mounted in the leaving water pipe downstream of the coil.
Three-Way Modulating Valves
These valves modulate the water flow through the coil in response to a signal from the Tracer
controller. Three-way valves allow water that is directed through the coil to mix with water directed
through the bypass line. This mixture exits through the leaving water pipe. Modulating valves are

General Data
Selecting the Correct Modulating Valve Size
Modulating valves are available in any of four port sizes: 0.7, 1.5, 2.5 or 4.0 Cv (coefficient of flow
values). The coefficient of flow is defined as the volume of water flow through a control valve in
the fully open position with a 1 psig differential across the valve. Calculate the coefficient of flow
using the formula:
Cv = Q/square root ΔP where:
Cv = flow coefficient
Q = flow rate (gpm)
ΔP = pressure drop across the valve or coil (psig).
For good control, the valve Cv should be approximately equal to the Cv of the water coil.
Modulating Valve Selection Example
Assume a size 06 vertical cabinet heater is selected to operate at the following conditions:
EWT = 180°F
LWT = 15 0°F
EAT = 70°F
The coil selection is a four-row coil. Select the best modulating valve size for this unit.
1. Find the ΔP across the water coil. Refer to the ARI performance table to determine the ΔP across
the water coil or use the Trane Official Product Selection System, TOPSS™, selection program.
The water pressure drop is found to be 5.7’ of water at a flow rate of 3.59 gpm. This converts
to a pressure drop of 2.47 psig (1.0 feet of water = 0.4328 psig.)
2. Calculate the Cv of the water coil.
Cv = gpm/Square root ΔP.
Cv = 3.59/Square root 2.47
Cv = 2.29
Therefore, select the 2.5 Cv valve because it is closest to the water coil.
Ta b l e 3 and Table 4, p. 21 illustrate possible valve selections at ARI conditions for horizontal
concealed units with a high static motor and vertical cabinet units with a free discharge motor. For
other applications, use TOPSS to determine flowrate and make calculations using the formulas
above.

Controls
ECM Engine Controller
The Electronically Commutated Motor (ECM) engine controls and reports the performance of up
to two Trane Brushless DC (BLDC) motors.
• The engine also coordinates the operation of the fan in response to electric heat behavior and
electric behavior in response to hydronic heat behavior.
• The engine incorporates a user interface that allows adjustment of certain unit parameters and
provides constant feedback on motor operation.
• The engine integrates service and troubleshooting tools.
• The engine integrates a versatile configurable auxiliary temperature sensor.
• The engine incorporates various safety and lockout features, such as maintaining proper fan
speeds if electric heat is called for.
Status Display
The ECM engine board contains a four-digit, seven-segment display that is used to present
information in a format close to real-world language, while having a small-form factor. Most
characters are immediately recognizable; however, please consult Tab le 19 and Tab le 20 for the
graphical representation of each alphanumeric character.

The adapter allows direct customer interfacing through the use of terminal strips. Standard
interfacing includes:
• Fan Speeds (H, M, L) (for wall mounted fan speed switches)
• Variable speed (0–10V) inputs
The standard adapter board eliminates many separate wiring harnesses in the panel and allows
simple, mistake-proofed single-plug interfacing of:
• The ECM engine controller
•Transformers
•Motors
• Valves
•Dampers
• Electric heat control
• Fan speed switches
• Main power (except electric heat)
The manual fan mode switch is available for fan-coil units that do not have Trane factory-mounted
control packages. This four-position switch (off, high, medium, low) allows manual fan mode
selection and is available unit or wall mounted. The unit-mounted option (Digit 31 = D) operates
on line voltage. The wall-mounted option (Digit 31 = K) is low-voltage and has three 24-volt relays
using a factory-wired transformer and relays to control the fan motor.

The control interface is intended to be used with a field-supplied, low-voltage thermostat or
controller. The control box contains a relay board which includes a line voltage to 24-volt
transformer, quiet contactors (for electric heat units), and an optional disconnect switch. All end
devices are wired to a low-voltage terminal block and are run-tested, so the only a power
connection and thermostat connection is needed to commission the unit. Changeover sensors and
controls are provided whenever a change-over coil is selected. When N.O. valves are selected,
inverting relays are provided for use with standard thermostats.
The CSTI adapter board provides all the hookups of the standard adapter board, but in addition,
provides hookups for valve control (main and auxiliary coils), electric heat control, and damper
control. Screw terminal blocks provide convenient access to fan controls and to end device control.
In addition, a courtesy 10-Vdc supply is provided for use with an external potentiometer or rheostat.
The 10-Vdc supply supports up to 10 mA draw.
Tracer Controls
The Tracer family of controllers (Tracer ZN010, ZN510, ZN520, and UC400) offer the combined
advantages of simple and dependable operation with the latest Trane-designed controller.
Standard control features include options normally available on more elaborate control systems.
All control options are available factory-configured or can be field-configured using Trane service
software. For more detailed information, refer to CNT-IOP-1 (for Tracer ZN010 or ZN510) or

Controls
In the stand-alone configuration, Tracer ZN520 receives operation commands from the zone
sensor. The zone sensor module is capable of transmitting the following information to the
controller:
• Timed override on/cancel request
• Zone setpoint
• Current zone temperature
• Fan mode selection (off-auto-high-med-low)
For optimal system performance, Force-Flo units can be linked to an Integrated Comfort System
(ICS) building automation system controlled by Tracer SC. The controller is connected to the
building automation system with a LON Talk communications network. The Trane ICS system can
monitor or override Tracer ZN520 control points. This includes such points as temperature and
output positions.
Tracer UC400, Model Number Digit 30 = J
The UC400 controller can be used in a stand-alone application or as part of a Trane Integrated
Comfort™ System (ICS).
In the stand-alone configuration, UC400 receives operation commands from the zone sensor
and/or the auto changeover sensor (on auto changeover units). The entering water temperature is
read from the auto changeover sensor and determines if the unit is capable of cooling or heating.
The zone sensor module is capable of transmitting the following information to the controller:
• Timed override on/cancel request
• Zone setpoint
• Current zone temperature
• Fan mode selection (off-auto-high-med-low)
For optimal system performance, fan-coil units can operate as part of an Integrated Comfort
System (ICS) building automation system controlled by Tracer SC. The controller is linked to the
building automation system using BACnet MS/TP. The building automation system can monitor or
override UC400 control points. This includes such points as temperature and output positions.
Service Software
A windows-based software package option allows field service personnel to easily monitor, save,
download, and configure Tracer unit controllers directly or through a communication link from a
portable computer. When connected over the communication link, the service software can view
any Tracer ZN controller that is on the same communication link. See Tracer TU or Rover literature
for more details.

Sequence of Operation
Fan Speed Switch
Off: Fan is turned off, two-position damper option spring-returns closed.
High, Medium, Low: Fan runs continuously at the selected speed. The two-position damper option
opens to an adjustable mechanical stop position.
Tracer ZN010 and ZN510
Off: Fan is off; control valves and fresh air damper option close.
Auto (Fan Cycling): Fan and fresh air damper cycle with control valve option to maintain setpoint
temperature. In heating mode it cycles from off to low (factory default that can be field-adjusted
using Rover service software). When heating is not required, the fan is off and the fresh air damper
option closes. The fan can also be field-configured (using Rover) to run at a user-defined speed
when the fan speed switch is in the auto position.
Low, Medium, High (Continuous Fan): Fan operates continuously while control valve option cycles
to maintain setpoint temperature. Fresh air damper option is open.
Tracer ZN520
Off: Fan is off; control valve options and fresh air damper options close.
Auto: Fan speed control in the auto setting allows the modulating (three-wire floating point) control
valve option and three-speed fan to work cooperatively to meet precise capacity requirements,
while minimizing fan speed (motor/energy/acoustics) and valve position (pump energy). As the
capacity requirement increases at low fan speed, the water valve opens. When the low fan speed
capacity switch point is reached, the fan switches to medium speed and the water valve repositions
to maintain an equivalent capacity. The reverse sequence takes place with a decrease in required
capacity.
Low, Medium, High: The fan will run continuously at the selected speed and the valve option will
cycle to meet setpoint.
Tracer UC400
Off: Fan is off; control valve options and fresh air damper options close.
Auto: Fan speed control in the auto setting allows the modulating (three-wire floating point) control
valve option and three-speed fan to work cooperatively to meet precise capacity requirements,
while minimizing fan speed (motor/energy/acoustics) and valve position (pump energy). As the
capacity requirement increases at low fan speed, the water valve opens. When the low fan speed
capacity switch point is reached, the fan switches to medium speed and the water valve repositions
to maintain an equivalent capacity. The reverse sequence takes place with a decrease in required
capacity.
Low, Medium, High: The fan will run continuously at the selected speed and the valve option will
cycle to meet setpoint.
Occupied Mode
In Occupied Mode, the UC400 controller maintains the space temperature based on the occupied
space temperature setpoint ± occupied offset. The controller uses the occupied mode as a default
mode when other forms of occupancy request are not present and the fan runs continuously. The
outdoor air damper, if present, will close when the fan is OFF. The temperature setpoints can be
local (hard wired), communicated, or stored default values (configurable using the Tracer TU
service tool).
Unoccupied Mode
In unoccupied mode, the UC400 controller attempts to maintain the space temperature based on
the unoccupied heating or cooling setpoint. The fan will cycle between high speed and OFF. In
CAB-PRC001-EN.book Page 34 Tuesday, May 8, 2012 10:11 AM
CAB-PRC001-EN 35
Controls
addition, the outdoor air damper remains closed, unless economizing. The controller always uses
the stored default setpoint values (configurable using the Tracer TU service tool), regardless of the
presence of a hard wired or communicated setpoint value.
Timed Override Control
If the UC400 controller has a timed override option (ON/CANCEL buttons), pushing the ON button
initiates a timed override on request. A timed override on request changes the occupancy mode
from unoccupied mode to occupied bypass mode. In occupied bypass mode, the controller
controls the space temperature based on the occupied heating or cooling setpoints. The occupied
bypass time, which resides in the UC400 controller and defines the duration of the override, is
configurable from 0 to 240 minutes (default value of 120 minutes). When the occupied bypass time
expires, the unit transitions from occupied bypass mode to unoccupied mode. Pushing the
CANCEL button cancels the timed override request. In addition, it will end the timed override
before the occupied bypass time has expired and transition the unit from occupied bypass mode
to unoccupied mode.
If the controller is in any mode other than unoccupied mode when the ON button is pressed, the
controller still starts the occupied bypass timer without changing to occupied bypass mode. If the
controller is placed in unoccupied mode before the occupied bypass timer expires, the controller
is placed into occupied bypass mode and remains in this mode until either the CANCEL button is
pressed on the Trane zone sensor or the occupied bypass time expires.
Zone Temperature Control
The UC400 controller has three methods of zone temperature control:
•Cascade zone control—used in the occupied, occupied bypass, and occupied standby
modes. It maintains zone temperature by controlling the discharge air temperature to control
the zone temperature. The controller uses the difference between the measured zone
temperature and the active zone temperature setpoint to produce a discharge air temperature
setpoint. The controller compares the discharge air temperature setpoint with the discharge air
temperature and calculates a unit heating/cooling capacity accordingly (refer to the illustration
below). The end devices (outdoor air damper, valves, and so on) operate in sequence based on
the unit heating/cooling capacity (0–100 percent).
If the discharge air temperature falls below the discharge air temperature low limit setpoint,
(configurable using the Tracer TU service tool), and the cooling capacity is at a minimum, the
available heating capacity is used to raise the discharge air temperature to the low limit.
•Simplified zone control— if discharge air temperature failure occurs, then simplified zone
controls runs. In the unoccupied mode, the controller maintains the zone temperature by
calculating the required heating or cooling capacity (0–100%) according to the measured zone
temperature and the active zone temperature setpoint. The active zone temperature setpoint
is determined by the current operating modes, which include occupancy and heat/cool modes.
•Discharge air temperature control— is the backup mode that runs only if there is not valid
zone temperature. In this mode, the active space temperature setpoint is used as the discharge
air temperature setpoint.

Important: This is not a normal operating mode. The source of the invalid zone temperature
needs to be corrected to restore normal operation.

Control Features
The following control functions are standard features on units with Tracer UC400, ZN010, ZN510,
ZN520, or UC400.
Occupied/Unoccupied Operation
The occupancy input utilizes a binary switch (i.e. motion sensor, timeclock, etc.) that allows the zone
sensor to utilize its unoccupied internal setpoints.
Random Start
This feature randomly staggers multiple unit startup to reduce electrical demand spikes.
Warmup
The two-position fresh air damper option closes during the occupied mode when the space
temperature is three degrees or more below the heating setpoint temperature. The damper
remains closed during warmup until the space temperature is within two degrees of the heating
setpoint temperature.

Manual Output Test Function
This feature is an invaluable tool for troubleshooting a unit. By simply pressing the controller’s test
button, service personnel can manually exercise outputs in a pre-defined sequence.
Peer to Peer Communication (Tracer ZN510, ZN520, and UC400)
Peer to peer communication allows multiple units in one space to share the same zone sensor and
provide simultaneous heating. The Tracer ZN510 or ZN520 controller can share information
between units on the same communication link using a twisted pair wire in the field. Unit
configuration must be modified with Rover service tool. On the UC400, zone sensor data sharing
can be accomplished by use of the BAS system controller.
Tracer ZN520 and UC400 Additional Features
Filter Maintenance Status
Tracer controller has an adjustable timer that indicates through the building automation system or
the service software tool when filter maintenance is necessary. Filter maintenance status is based
on cumulative fan run hours.
Water Valve Override
Using the building automation system or the service software tool, the water valve override
function drives all water valves in every unit fully open simultaneously. This helps reduce the time
required for waterside balancing.
Cascade Control
Tracer controller maintains discharge air temperature using a cascade control algorithm. The
discharge air temperature is based on the difference between the space temperature and setpoint.
Unit capacity modulates to achieve the discharge air temperature.
Interoperability
Tracer ZN520 can be used with a Tracer Summit system or on other control systems that support
LonTalk® and the SCC profile. For more information on specific inputs and outputs, see UNT-IOM-6
(Installation, Operation, and Maintenance: UniTrane® Fan-Coil Room Conditioners - Force Flo™
Cabinet Heaters), or the most recent version.
The Tracer UC400 can be used with the Tracer SC or another BACnet MS/TP building automation
system. For more information see the Installation Operation and Programming Guide BAS-SVX48
for more information.
End Device Options
All end device options are factory-installed and -tested.
Two-Position Control Valves; Model Number Digits 27 & 28 = A–H
Two-position valve options are available with either Tracer ZN010, ZN510, ZN520, or UC400. Valves
are spring-return type, sweat connections, and available as normally open or closed. The valves
respond to a 24 V signal and have 1/2-inch sweat connections. The two-way valve option will either
fully open or close. The three-way valve option allows either full water flow through the coil or
diverts waterflow through the bypass. If the control valve loses power, the valve returns to its de-
energized position. All control valve options are factory installed in the leaving water piping
downstream of the hydronic coil. The valve actuator is easily removable for service without
removing the valve body from piping.
Modulating Control Valves (Tracer ZN520 and UC400); Model Number Digits 27
& 28 = J–R
These 1/2-inch sweat connect valves are three-wire floating point valves, equal percentage type.
Modulating valves are available in four Cv sizes: 0.7, 1.5, 2.5, and 4.0. The valve responds to a 24 V

triac signal from the controller, which determines the valve position by a control algorithm. If the
valve loses power, it remains in the position that it was in when the power loss occurred. All control
valves are factory installed in the leaving water piping downstream of the hydronic coil.
Field-Supplied Valves; Model Number Digits 27 and 28 = X, Y, Z or 1.
When using field-supplied valves, this option allows the controller to be factory-configured for the
normal position of the field-supplied valve.
Note: Trane does not recommend wild coil applications.
Two-Position Fresh Air Damper Actuator; Model Number Digit 13 = D, E, or F
(Available with all control options except Tracer ZN520)
This damper actuator uses a 24 V signal and is factory-wired and mounted to the damper assembly.
It allows zero to 50 percent fresh air. The damper will drive open to an adjustable mechanical stop-
position whenever the fan is running during occupied mode and will spring-return closed when the
fan turns off.

Electrical Data
Minimum Circuit Ampacity (MCA) and Maximum Fuse Size (MFS) Calculations
Units with Electric Heat. HACR (heating, air conditioning, and refrigeration) type circuit
breakers are required in the branch circuit wiring for all units with electric heat. To compute MCA
and MFS, see Table 26, p. 44 through Table 29, p. 44 for motor FLAs and Table 23, p. 41 through
Table 25, p. 42 for electric heat amps.
Calculating electric heat amps:
Single stage, three phase = heat kW * 1000/1.732/volts
Two stage, three phase = total heat kW * 1000/1.732/volts
Note: Use 240 V heat voltage for 230 V units.
Calculating MCA (units with electric heat):
MCA = 1.25 * (heat amps + sum of all motor FLAs)
Calculating MFS (units with electric heat):
MFS = (2.25 * largest motor FLA) + second motor FLA, size 10-12 units only + heat amps
Use the closest larger fuse or HACR circuit breaker above the MCA. Standard fuse sizes are: 15,
20, 25, 30, 35, 40, 45, 50, 60 amps.
Electric heat MBh = heater kW * 3.413
Units without Electric Heat. To compute MCA and MFS, see Table 26, p. 44 through Tab le 2 9,
p. 44 for motor FLAs and Table 23, p. 41 through Table 25, p. 42 for electric heat amps.
Calculating MCA (units without electric heat):
MCA = (1.25) x largest motor FLA + second motor FLA, unit sizes 10 and 12 only
Calculating MFS (units without electric heat):
MFS or HACR1 type circuit breaker = 15 amps for all units without electric heat.
1HACR (heating, air-conditioning and refrigeration) type circuit breakers are required in the branch circuit wiring for all size 10 and 12
units.
