FDU - Underfloor Fan Powered Booster & Terminal Unit
FDU, UMCBOverview
The Underfloor Terminal Unit (FDU) is available in various sizes and configurations in order to meet any application need. In cooling mode, plenum air is pulled through the fan and delivered to the perimeter to meet envelope loads. In heating mode, hot water or electric reheat coils can be used to warm the air up to meet heating demand.

- Deluxe ECM speed controller with digital RPM readout and feedback
UMCB Zone Controller
The UMCB is used to control up to 12 remote terminal dampers. By supplying the UMCB complete with a Price thermostat, the UMCB will control the fan operation, as well as electric heat based on the thermostat’s signal. The UMCB is a native BACnet controller, and can be controlled by a building automation system (BAS) instead of a thermostat using simple to connect RJ-45 BACnet ports. The UMCB comes mounted to terminal unit as standard, powered by an integral transformer.
Features
- 19 terminal block connections capable of output signals such as cooling and heating control, ECM fan motor control, fan relay, reheat (binary, analog, and tristate), etc.
- Two thermistor and 1 sensor connections that can be used for humidity or pressure sensing
- Two RJ12 output jacks to convey power and control signal to 12 remote terminals
- Two RJ45 jacks for network connection
- Six thermostat options: Room Sensor, Dial, LCD, LCD with Motion Sensor, LCD with CO2 and Humidity Monitoring, and Wireless Dial
