I have an Amana heat pump and air handler with a Honeywell Prestige thermostat which was all newly installed this past July. I have noticed that the Auxiliary heat is probably on about 15 minutes per hour. The house temp is set at 68 and the outdoor temp has been in mid forty to mid 50 range. Even when temp in house is at 68 the auxiliary heat comes on. My last months electric bill was through the roof and I think it is because aux heat was on so much. The company who installed it is coming out tomorrow to look but they were out a month ago and said everything was fine. Clearly something is wrong. Is there a temperature setting that triggers when aux heat comes on that is maybe set too high?
