Thermostat keeps reverting to 60-62 degrees. Will not come on now if I hit temp up key and hold. If I hit run program it displays 68 degrees which is should, then reverts to 60 degrees and heater does not come on. Though last night I heard the heater running but it never got above 60 degrees. Do I need to reset the thermostat and how?
