- Model FHC 1D - Fan and Heater Control



The Fan and Heater Control automatically controls the temperature in a room by adjusting the speed of variable speed fans and controlling a heater interlock. When the temperature is at the temperature set point, the FHC-1D operates the fans at the idle speed setting and the heater is off. When the temperature exceeds the set point, the FHC-1D increases the speed of the fans. When the temperature drops below the set point, the FHC-1D shuts off the fans (in shut-off mode) or operates the fans at idle speed (idle mode) and switches on the heater or heat lamps. The FHC-1D is ideal for poultry, livestock, greenhouse, or light industrial buildings.
