Furnace turns off and on too quickly
Asked Jan 24, 2007, 04:21 PM
Please help. I installed a new programmable thermostat (Noma) to replace the old noma one we had.
It heats when asked and it cools when asked. The problem is that if the thermostat is set to 18.5 the furnace goes on as soon as it goes 18.3 and stops at 18.8, which maintains the house at the requested 18.5.
My husband seems to think that this consumes more oil than if it had a wider range because the furnace goes on only for a few minutes then stops but because it's winter it does that constantly.
Please let me know if he's right (I'll never tell!) or if I can finally get him to stop complaining about the new thermostat.
