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.

Note: This is data is based on horizontal concealed model only, with duct inlet, duct outlet and no filter, dry coil, all voltages except 208 V.
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
16 |
CAB-PRC001-EN |
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 |
17 |
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.
Two-Way/Two-Position Valves
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 twoway 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

three-wire floating point equal percentage valves, and are factory mounted in the leaving water pipe downstream of the coil.

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 P where:
Cv = flow coefficient
Q = flow rate (gpm)
P = 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 = 150°F
EAT = 70°F
The coil selection is a four-row coil. Select the best modulating valve size for this unit.
1. 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’ 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 P. 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.
Table 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.
