I have an interesting problem. My heat wont turn off at set temperature. Checked wiring at thermostadt and Honeywell controller. This is a new house, it was working fine through the summer and into the fall, it was cooling fine and heating fine and them one night I woke up to 90 degree temps in the bedroom. Any ideas?

Did the heat turn off when you switch the t-stat to "OFF" mode?

What happen when you turn it back to heat?

Do you have gas or electric heat?

Electric heat squencers can cause this...
