Hi, I have a problem that has stumped me and I can't find a good previously posted thread about it.
My house has forced air heating and a run of the mill, standard round mercury thermostat. At the beginning of the day when I wake up, the temp will be really low in the house (I have seen it drop to below 50 degrees). I then turn the thermostat all the way down to 0, then back up to 70. The forced air furnace then switches on and starts to heat up the place. It stops when it gets to about 70 and then it shuts off again until I manually "reset" it.
Any ideas?
