Question about Honeywell CT87B ROUND HEATING&COOLING MECHANICAL THERMOSTAT - WHITE Heater
I just bought a house and my furnace does not heat the house to the temperature. set at 70 it heats to 75 Warren in Ohio
Are you saying that the temperature over-shoots it's setting by 5 degrees? If so and if the thermostat has an inticipator device in it you can adjust it. After removing the cover on the thermostat, look for a little brass triangle on the lower right hand side. There will be a scale with numbers on it and they are very hard to see. This device heats up prior to shutting off the thermostat so it will not over-shoot by more than a few degrees. Move the brass triangle either up or down and let the heater cycle a few times. If the temperature swing gets worse, go the other way next time.
If the thermostat is not heat inticipated, there will be a small "Dip" switch where you can adjust to a specific degree of under-shoot.
Visit the Honeywell website and you can pull up the installation/owners manual for your model. www.honeywell.com
