I just installed a new Hunter 44155C programmable thermostat a few days ago and the AC works as it should, but when I turned on the heat this morning the furnace continued to run well past the set temperature and did not shut off until I turned the furnace off on the thermostat. I've been trying to troubleshoot this all morning and I cant figure out why it's doing this. Any help from here would be appreciated.
