My thermostat resets itself
I set the thermostat at 70 degrees and press hold. But a couple hours later it resets itself to 60 degrees its default temperature. It was doing this with the air conditioner too. It would reset itself to 85 degrees. I changed the batteries and vaccumed and washed the filter but it still does this. What do I need to do to fix this/

BE absolutely sure the batteries are good. This is what usually causes this symptom, even it the 'battery indicator' isn't asking for a new battery. It happens a lot on systems that are being turned off with the breaker, safety or service switch; DON'T do that. When you put a set of brand new alkaline or lithium batteries, with the thermostat off the wall, leave NO batteries in it for about an hour. Be sure that the power is on 24/7 to the system. To stop the system from running, always use the "Heat--Off--Cool" switch.
