Phason® Fan and Heater Control

When room temperature is at set point the FHC-1D operates the fans at idle speed with heaters off.  As temperature starts to increase above set point the FHC-1D increases fan speed.  When temperatures drop below set point the FHC-1D operates the fans in either shut-off mode or idle speed and switches on heaters or heat lamps.
