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.
