Honeywell chronotherm IV Plus thermostat

I have a honeywell chronotherm IV thermostat. For some reason it seems to have stopped working sometime this afternoon. (the screen has gone blank)

I tried flipping the fuse box and it did not help. I am looking to see if there is perhaps a battery that I can replace but have not yet seemed to locate one. I don't believe it's the heating system in the house as the heat has been working properly without incident.

Do you have any suggestions?

     I have the same problem, blank screen.  Heating system is working fine.  I can find no batteries in the thermostat.  I wonder if there is a problem in the thermostat circuitry.

I can't turn my Chronotherm IV plus off! Can anyone help me. It is going to cost a fortune


Depends what model number you have. The older models had problems. So Honeywell upgraded the model several times. When you say, cant turn it off. If that means the heat will not shut off then you have no choice to replace it, also if the heat,cool, off,switch will not work it is not repairable. Go to Home depot or menards and pick up a thermostat. Find somebody with some handy man skills and they can replace it for you.

Honeywell Chronotherm iv fan keeps running even when heat and cool turned off. How do I turn it off?


To turn the fan off, press the "fan key" until it says "auto". This will turn the fan off. When the programs scheduled, changes, the fan will go on again. You have to repeat the fan to "auto" each time the schedule changes.

Honeywell Chronotherm iv fan keeps running even when heat and cool turned off. How do I turn it off?


Assuming you have the fan switch of your thermostat in AUTO, it sounds like a stuck Fan Relay. If the fan relay is stuck, your fan will continue to run as long as there is line voltage being fed to your unit. This relay could be an independent component or it could be an integral part of your control board. Have an experienced, qualified service technician check it out.

My Honeywell chronotherm IV Plus thermostat intermittent problem


The Chrono Therm 3 and 4's were some of the worst products that honeywell has EVER put out. I would suggest switching to the Vision Pro 8000, please consult your local HVAC company for more information regarding the change over.

I have a Honeywell Chronotherm IV Plus a/c unit and I can't get my air condt. to turn on. The room temp. says it's 17 degrees in the house so it won't turn on. I need to know how to reset the room tempt....


Not only are the Chronotherm IV's less than user friendly, they have a terrible failure rate. It sounds like one of the typical failures of the chronotherm IV. I suggest starting with a new thermostat.
