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.
