Hunter 42122 Thermostat was installed operating an Amana BBA36A2A Central Air / Heat Pump / Aux Heat electric unit. Switches in correct positions. The problem is that the aux heat does not come on. "Aux Heat" flashes in the Display of the 42122, but does not go to steady. My wiring is attached to coincide with Hunter's "Single Stage Heat Pump w/ Aux heat" schematic shown on installation sheet that accompanied the 42122
