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.  
• All wall-mounted zone sensors require  
only low voltage control wiring from  
the device to the unit control box. (No  
line voltage.)  
necting 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 Summit® 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  
• The Tracer® controls family introduces  
the latest in control technology with the  
ZN.010, ZN.510, and ZN.520 controllers.  
• The random start-up feature helps  
reduce electrical demand peaks by  
randomly staggering multiple units at  
start-up.  
The Force–Flo cabinet heater is the leader  
in these key areas:  
• Indoor Air Quality (IAQ)  
• Controls  
• Occupied/unoccupied operation allows  
the controller to utilize unoccupied  
temperature setpoints for energy  
savings.  
• Warm-up energy feature is standard  
with Trane 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 fully  
comply with ASHRAE 62.  
• Continuous fan or fan cycling is avail-  
able with ZN.010 or ZN.510.  
• Inverted unit models allow heating to  
circulate from the bottom of the unit.  
• Monitor unit operation using Tracer®  
Summit building management system  
with ZN.510 or ZN.520.  
Quality  
• Coils and piping packages are air and  
leak-tested before mounting on the  
unit.  
• To customize unit control, Tracer  
Summit or Rover™ software will allow  
field modification of ZN.510 and ZN.520  
default settings. For ZN.010, use Rover  
to field modify default settings.  
• Maximize cabinet heater system  
efficiency with modulating valves on  
units with ZN.520.  
• 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.  
IAQ Design  
• Closed-cell insulation is standard on all  
units to help prevent fiberglass in the  
airstream.  
Flexibility  
Serviceability  
• Two, three, and four-row hot water coils  
allow greater design flexibility. Steam  
distributing or electric heat coils are  
also available.  
• 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® ZN.510, ZN.520, or ZN.010;  
service personnel can manually  
exercise outputs in a pre-defined  
sequence.  
• Easy filter access encourages frequent  
changing.  
• Force–flo cabinet heaters have a blow-  
thru design.  
• 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.  
Controls  
• All controls are factory-mounted and  
tested to minimize field setup.  
• Controls are wired with a 24 VAC  
transformer to keep only a single  
source power connection requirement  
to the unit.  
• Factory piping options include intercon-

General Data  
Electric Heat  
control options use PWM (pulse-width  
modulation) outputs to calculate the  
electric heat output 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%, the controller controls the  
electric heat output on for approximately  
four minutes each period.  
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.  
Safety Features  
• 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 step-  
down transformer.  
• A unit mounted magnetic contactor(s) is  
(are) supplied on all unit voltages.  
• A high temperature cutout with auto-  
matic reset de-energizes the electric  
heat in the event of an overheat condi-  
tion.  
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 any of the Tracer® ZN  
control options. Two-stage electric heat is  
controlled by the Tracer ZN.520 only. Both

Piping Packages  
End Valves  
• Two-Way/Two-Position Valves  
Factory-Installed Piping  
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.  
These valves will either fully open or  
close in response to a 24VAC signal from  
the Trane controller. Control valves are  
direct-acting valves. The control valve is  
factory mounted in the leaving water pipe  
downstream of the coil. Some means of  
relieving pump head pressure should be  
accounted for when two-way valves are  
selected. Normally open or normally  
closed valves are available.  
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.  
• 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 degrees  
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.  
• 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 24VAC signal from the Trane  
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.  
Piping Package Components  
Force–Flo piping packages consist of a  
variety of components for each applica-  
tion. The following section provides a  
detailed description of the piping compo-  
nents. Following this section are addi-  
tional illustrations and specifications.  
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.  
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.  
• Two-Way Modulating Valves  
These valves modulate the water flow  
through the coil in response to a signal  
from the Trane controller. Modulating  
valves are three-wire floating point equal  
percentage valves, and are factory  
mounted in the leaving water pipe  
downstream of the coil.  
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 so the correct setting can  
be found quickly.  
Interconnecting Piping  
Interconnecting piping refers to the  
copper piping which is attached to the  
coil connections and all other compo-  
nents 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.  
• Three-Way Modulating Valves  
These valves modulate the water flow  
through the coil in response to a signal  
from the Trane controller. Three-way  
valves allow water that is directed  
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.  
through the coil to mix with water that is  
directed through the bypass line. This  
mixture exits through the leaving water  
pipe. Modulating valves are three-wire  
floating point equal percentage valves,  
and are factory mounted in the leaving  
water pipe downstream of the coil.  
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. The strainer body  
is cast brass construction, with a stain-  
less steel mesh strainer that is easily  
removed for cleaning. The unions are  
forged brass construction and close with  
a minimum amount of effort.  
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.

Selecting the Correct  
Modulating Valve Size  
Modulating valves are available in any of  
four port sizes. These four port sizes  
relate to a Cv of 0.7, 1.5, 2.5 or 4.0, which  
is the coefficient of flow. 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 (6.895 kPa)  
differential across the valve. It is calcu-  
lated using the following formula:  
Cv = Q/Square root ∆P where:

Find the ∆P across the water coil. Refer to  
the ARI performance table to determine  
the ∆P 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’ (17.0  
kPa) 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.)

Calculate the Cv of the water coil.  
Cv = GPM/Square root ∆P.  
Cv = 3.59/Square root 2.47  
Cv = 2.29  
Therefore, select the valve with the Cv of  
2.5 since it is closest to the Cv of the  
water coil. The following tables illustrate  
possible valve selections at ARI condi-  
tions 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 the flowrate and make  
calculations using the formulas above.

Controls  
Control Options  
Force–Flo cabinet heaters are available with four different control options:  
• Manual three-speed fan switch  
• Tracer ZN.010  
• Tracer ZN.510  
• Tracer ZN.520  
Manual Fan Mode Switch  
Model Number Digit 30 = A and Digit 31 = D or K  
The manual fan mode switch is a four-position switch (off, high, medium, low) that  
allows manual fan mode selection. 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.  
Tracer® Controls  
The Tracer family of controllers (ZN.010, ZN.510, and ZN.520) 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 Rover™ service software. For more detailed information, refer  
to the Trane publication, CNT-IOP-1 or CNT-IOP-2.  
Fan Speed Switch  
Tracer ZN.010  
Model Number Digit 30 = E  
Tracer ZN.010 is a stand-alone microprocessor controller.  
Tracer ZN.510  
Model Number Digit 30 = F  
ZN.510 can be used as either a stand-alone or communicating microprocessor  
controller.  
Tracer ZN.520  
Model Number Digit 30 = G  
The ZN.520 controller can be used in a stand-alone application or as part of a Trane  
Integrated Comfort™ System (ICS).  
In the stand-alone configuration, ZN.520 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  
ZN.010 Control Board  
• 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 Summit®.  
The controller is connected directly to the Summit control panel via a twisted pair  
communication wire, requiring no additional interface device (i.e., a command unit).  
The Trane ICS system can monitor or override ZN.520 control points. This includes  
such points as temperature and output positions.  
Rover™ Service Software  
This windows-based software package option allows field service personnel to easily  
monitor, save, download, and configure Tracer controllers through a communication  
link from a portable computer. When connected to the communication link, Rover can  
view any Tracer controller that is on the same communication link.

Sequence of Operation  
Fan Speed Switch  
Off: Fan is turned off, two-position  
damper option spring-returns closed.  
ZN.520  
Off: Fan is off; control valve options and  
fresh air damper options close.  
High, Medium, Low: Fan runs continu-  
ously at the selected speed. The two-  
position damper option opens to an  
adjustable mechanical stop-position.  
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 require-  
ment 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 se-  
quence takes place with a decrease in  
required capacity.  
ZN.010 and ZN.510  
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 cooling  
mode, the fan cycles from off to medium  
and 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-config-  
ured (using Rover) to run at a user-  
defined speed when the fan speed switch  
is in the auto position.  
Low, Medium, High: The fan will run  
continuously at the selected speed and  
the valve option will cycle to meet  
setpoint.  
Low, Medium, High (Continuous Fan): Fan  
operates continuously while control valve  
option cycles to maintain setpoint

Features  
Controls  
configuration must be modified with  
Rover service tool.  
Control Features  
The following control functions are  
standard features on units with Tracer  
ZN.010, ZN.510, or ZN.520.  
ZN.520 Additional Features  
Fan Status  
The ZN.520 controller monitors the fan  
output status to determine if the fan is  
operating.  
Occupied/Unoccupied Operation  
The occupancy input utilizes a binary  
switch (i.e. motion sensor, timeclock, etc.)  
that allows the zone sensor to utilize it’s  
unoccupied internal setpoints.  
Filter Maintenance Status  
The controller has an adjustable timer  
that indicates through Summit or Rover  
when filter maintenance is necessary.  
Filter maintenance status is based on  
cumulative fan run hours.  
Random Start  
This feature randomly staggers multiple  
unit start-up to reduce electrical demand  
spikes.  
Warm-up  
Water Valve Override  
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 tem-  
perature. The damper remains closed  
during warm-up until the space tempera-  
ture is within two degrees of the heating  
setpoint temperature.  
Using Summit or Rover, 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  
The 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.  
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.  
Interoperability  
Peer to Peer Communication (ZN.510 and  
ZN.520)  
The ZN.520 controller can be used with a  
Tracer Summit system or on other  
control systems that suport LonTalk and  
the SCC profile. For more information on  
specific inputs and outputs, see the  
Installation, Owner, and Maintenance  
Manual, UNT-IOM-6.  
Peer to peer communication allows  
multiple units in one space to share the  
same zone sensor and provide simulta-  
neous heating. The ZN.510 or ZN.520  
controller can share information between  
units on the same communication link  
using a twisted pair wire in the field. Unit

Options  
Controls  
when the power loss occurred. All  
control valves are factory installed in the  
leaving water piping downstream of the  
hydronic coil.  
End Device Options  
All end device options are factory-  
installed and tested.  
Two-Position Control Valves  
Field-Supplied Valves  
Model Number Digits 27 and 28 = A - H  
Two-position valve options are available  
with either Tracer ZN.010, ZN.510, or  
ZN.520. Valves are spring-return type,  
sweat connections, and available as  
normally open or closed. The valves  
respond to a 24V 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.  
Model Number Digits 27 and 28 = X or Y  
When using field-supplied valves, this  
option allows the controller to be factory-  
configured for the normal position of the  
field-supplied valve.  
Note: The Trane Company does not  
recommend wild coil applications.  
Control Valve  
Two-Position Fresh Air Damper Actuator  
Model Number Digit 13 = D, E, or F  
(Available with all control options except  
ZN.520)  
This damper actuator uses a 24V signal  
and is factory-wired and mounted to the  
damper assembly. It allows zero to 50%  
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.  
Modulating Control Valves (ZN.520)  
Model Number Digits 27 and 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 24V triac  
signal from the controller, which deter-  
mines the valve position by a control  
algorithm. If the valve loses power, it  
remains in the position that it was in

Note:  
Values for fractional HPs (kWs) are approximate values and  
not necessarily the actual HP (kW).  
Calculating MFS:  
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 Tables  
ED-2 through ED-5 on page 31 for motor  
FLAs and Tables ED-6 through ED-8 on  
pages 32-33 for electric heat amps.  
Calculating MCA:  
MCA = (1.25) x largest motor FLA +  
second motor FLA, unit sizes 10-12 only  
Calculating MFS:  
MFS or HACR1 type circuit breaker = 15  
amps for all units without electric heat.  
1 HACR (heating, air-conditioning and  
refrigeration) type circuit breakers are  
required in the branch circuit wiring for  
all size 10 and 12 units.
