Hunter Programmable Thermostat Model 44760
Daytime temperature setting on the thermostat is 68 degrees but the thermostat will always go to 69 degrees before shutting off. The problem is when the thermostat gets to the set temperature of 68, the auxiliary heat will come on to reach 69 degrees - even when it is 50 degrees outside. Why won't the thermostat cut off when it reaches the set temperature and not use the auxiliary heat? If I set the temperature lower, it does the same thing! We are wondering if we should replace this thermostat?
Thank you for your help.
