I have a 5 ton Climatemaster Tranquility 27 hooked to a Honeywell VisionPro TH8000 (TH8320U) thermostat that heats and holds my house temp just fine. If I use the programmable features and lower my temp at night, can I prevent the EM heat frin coming on in the morning? I don't mind waiting on the longer recovery time of the geo. I just hate sending more to the utility company than I have to. Would changing to system type in the thermostat to 2 heat/2cool heat pump (no aux. heat) trick it into leaving my EM heat off? I don't have the remote outside temp. Thanks!
