Speaking of thermostats, I have an issue where mine will read too cool by 5 degrees or more and then because it shows so cool the emergency heat strips kick in when it's not needed. I'm only replying to your post because you made me think of it but this may be a stupid question but can I just replace the thermostat for a heat pump or will any thermostat work with it? I mean every thermometer in the house will read 68 for example but the thermostat will show 63 and rip those heat strips, it does the same too warm sometimes too. Crazy
