The SC045 series thermostat is a low cost, single set point thermostat intended for use as a temporary device to provide heating or cooling to allow drywall to dry during construction. It can also can be used as a low ambient cutoff switch for condenser fan motors and compressors.
Mode of Operation:
- 2 wire installation
- Temporary use for dryout applications
- Can be used as a low ambient cutoff switch
- Cutoff set point 45°F
Cool Thermostat - The cooling models will close when the ambient temperature is above the respective set point and open when the ambient temperature drops below the respective set point.
Low Ambient Cutoff - Condenser Fan Motor -
The SC045 model can be used as a low ambient cutoff switch for a condenser fan motor. When the ambient temperature drops below the set point, the unit will open the fan signal and turn the fan motor off. It will not allow the fan to turn back on until the temperature rises above the set point.
Low Ambient Cutoff: Compressor -
The SC045 model can also be used as a low ambient cutoff switch for the compressor when wired in series with the Y circuit from the thermostat. When using with the compressor circuit, an anti-short cycle timer is recommended to prevent possible damage to the compressor from short cycling.
