Power from an alternate power supply that is non-sinusoidal may
damage the furnace electronics or cause erratic operation.

* Permissible limits of the voltage range at which the unit operates satisfactorily.
# Unit ampacity = 125 percent of largest operating component’s full load amps plus 100 percent of all other potential operating components’ (EAC, humidifier,
etc.) full load amps.
TTime—delay type is recommended.
Length shown is as measured one way along wire path between furnace and service panel for maximum 2 percent voltage drop.
