Room Temperature Control - 4200 Series

The room temperature set point is adjusted at the wall thermostat. If room temperature drops below the thermostat set point, the thermostat initiates a heat call and energizes the blowers in Serenity. The variable speed core blowers automatically adjust speed in relation to brick core temperature and duct temperature to circulate room air through the brick core. The supply air blower then delivers the heated air into the living area through the duct system to satisfy heating requirements. When the thermostat senses a demand greater than the output, another stage of heating is initiated. When used to supplement heat pump systems, Serenity replaces the resistance strip heat, which is typically required as a supplement or back-up to the heat pump system. A duct sensor monitors the discharge air temperature. If the demand for heat is at a point where the heat pump alone cannot maintain the desired duct temperature, stored heat is used to supplement the heat pump and satisfy the heating requirements.
