Question About White Rodgers Thermostat 1F89-11
Red light...

The thermostat will not keep the setting - we set it for 77 or 78 and discover that it has "defaulted" up to 82. Not sure what this will mean when the weather turns cold and we use heater rather than the air conditioner. Do I need to replace the entire thermostat?
