Hello all. I have an issue with the Honeywell CM907 thermostat. I have it set on Automatic and the heating in the house is supposed to turn off at 10pm and not come back on until 6am. However it seems to be going on and off throughout the night and now im worried that I am going to accumulate and huge bill. Is there some sort of setting to stop this from happening or could it be a fault? Any help will be greatly appreciated. We are in a brand new house and its only 4 months old. Thanks.
