Lifebreath AH60BHW, AH40DHW, AH60DHW, AH40BHW, AH80BHW Electrical, Air Handler Wiring Diagram

Electrical

The Air Handler operates at 120V, singles phase and draws anywhere from 2-8.7 amps, depending on fan speed.

The low voltage thermostat (not provided) connects to the R & W terminals for heating and the R & Y & C terminals when calling for cooling.

Caution should be used if installing a setback thermostat to control the system. If the thermostat is set back too far, and, for example, is set to call for a lot of heat when you get out of bed, at which time showering and general water use is at its peak, then the hot water heater may not keep up.
