Customer Question

Replaced a Honeywell T834C1137 with a T834N1002 thermostat. Now the furnace heats up and when it gets to temp the gas valve shuts off and the fan runs to complete cycle. Then the gas comes on again an keeps heating even though points on thermostat have opened.

Ok well if you set it at another heat cycle and watch the points on t-stat with the cover off after the end of cycle, the only way that furnace will start up again is t-stat ,
