BOUGHT AND REPLACED A HONEYWELL ROUND THERMOSTAT AND THE HEAT WILL GO ON BUT WILL NOT SHUT ITSELF OFF WHEN THE TEMPERATURE GETS TO THERE. IT KEEPS RUNNING TILL I SHUT THE THERMOSTAT OFF. I FOLLOWED THE DIRECTIONS AND MADE SURE IT WAS WIRED THE SAME AS THE OLDER ONE.I HAVE TRIED CHANGING THE SETTINGS ON THE NEW ONE AND THEN BACK BECAUSE IT DID NOT WORK. I JUST DO NOT GET WHY THIS THING WILL RUN TILL THE COWS COME HOME AND WILL NOT SHUT OFF AT THE TEMP IT WAS SET AT.

Look at the old thermostat and in the middle of it theres a arrow that is pointing at numbers that is called a heat anticipator. then on the new thermostat make sure that its set the same.

30 yr. old honeywell thermostat would not shut off


Try removing the front cover and visually inspecting the metal coil. If there's a lot of dust you will need to blow it off. It could just be that the coil is packed and isn't registering temperature properly.

How to use a round circular honeywell thermostat? I turned round casing to mark heat , no heat on??


If you turned the ring and the pointer moved, then you are using the thermostat correctly. Turn the thermostat up above room temperature (the temp on the bottom of the thermostat) Make sure all your switches are on, and that the fuse or circuit breaker is also on. If you still do not have heat after verifing all these things, then it is most likely a problem with the heating appliance.
Also, if it is a heating and cooling thermostat, make sure your lever is in the heating mode. Hope this helps

Honeywell Thermostat RTH7400D


The thermostat will not cut off the A/C until the thermometer reading gets to 76.

If there is not a heat source near/behind the thermostat which is causing the thermometer to read higher than actual room temperature, it sounds like the thermostat thermometer is out of calibration.

There are ways to calibrate it, but much to involved to go into here.

One solution is to just set the thermostat at 80, knowing that it's really set on 76.

Another solution is to replace the thermostat.

Fan on but no heat


I never liked the user un-friendliness of the Chromatherm, I would suggest finding a thermostat that you can understand and operate. Yes the Chromatherm is a good one, but so damned hard to figure out. Stay away from thermostats that still use mercury. Good Luck!

Honeywell round mercury thermostat - heat not coming on


If you tip the mercury switch so that it makes contact and the furnace doesn't start, it isn't the t-stat. Check the connections, then start checking the furnace.
In any case, ditch the mercury t-stat (recycle it properly) and get a new programmable one if at all posible. It will pay for itself many times over by turning your heat down in the middle of the night and back up by morning.

Thermostate temperature setting wrong


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
