The Force-Flo™ cabinet heater is the leader in these key areas:

• Energy Efficiency
• Indoor Air Quality (IAQ)
• Controls
• Flexibility
• Quality
• Serviceability

Energy Efficiency

The exclusive use of Electronically Commutated Motors (ECM) incorporates the latest technology for optimized energy efficiency, acoustical abatement, maintenance-free, and extended motor life.

Each ECM:

• has a built-in microprocessor that allows for programmability, soft ramp-up, better airflow control, and serial communication.
• lowers operating costs on average of 50 percent (versus a PSC motor).
• has a reduced FLA option that allows the unit to ship with a nameplate FLA rating much lower than a typical unit.

Indoor Air Quality (IAQ)

• Standard Closed-cell insulation prevents fiberglass in the airstream.
• Easy filter access encourages frequent changing.

Controls

• Available control options:
  • Fan speed control (provided when no control package is selected)
  • Customer-supplied terminal interface (CSTI)
  • Low voltage Thermostat
  • Tracer® ZN520 controller
  • Tracer® UC400-B controller with optional Air-Fi® Wireless Communications Interface
• All Trane control options:
  • are factory-mounted, configured, and tested to minimize field setup and improve reliability.
  • wired with a 24 Vac transformer to keep only a single source power connection requirement to the unit.
  • automatically determine the unit’s correct operating mode (heat/cool) by utilizing a proportional/integral (PI) control algorithm to maintain the space temperature at the active setpoint, allowing for total comfort control.
• Monitor unit operation using Tracer® TU building management system with Tracer® ZN520 and UC400-B.
• To customize unit control, Tracer® TU or Rover™ software will allow field modification of Tracer® ZN520 default settings. UC400-B uses Tracer® TU.

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.
• 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 schools 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 fan coil.
• 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® ZN520 service personnel can manually exercise outputs in a predefined sequence.
