Question about Honeywell Programmable Thermostat Heater
Honeywell rectangular Model #RTH221B. It gets stuck on temperature (65 degrees). When I set it at desired temperature (67 degrees) and push hold it keeps going back to 65 degrees. I thought setting a temperature and pushing hold would overide any programming that is set.
Make sure it is not telling you room temp, some of the Honeywells, will display room temp over desired temp. check that, if it wont let you switch temp than buy a new one, if you dont have a heat pump a new cheap stat is around 20.00.
