Question about Honeywell Programmable Thermostat Heater

1 Answer

I have the Honeywell Chronotherm IV Plus system. I usually have it on a set schedule to come on or off at specific times. It worked fine all day, but now it seems to be doing the exact OPPOSITE of what it was programmed to do (cutting OFF when it should be coming ON).. I decided to reset the whole programs, & just set it manually without using set times...Now the heat wont come on AT ALL, even when i use the "temporary" temp setting. I have 2 NEWBORNS IN MY HOUSE HELP!!

Hi,
To get heat and to find out if it is the t-stat or the furnace...take the front off of the t-stat and look for the "R" and the "W" wires....turn the power off to the furnace... then twist those two wires together... turn the power back on and the furnace should start... if not then the problem is in the furnace...
if the furnaces starts then replace the t-stat it is fired....but at least this will get you heat till you get a new t-stat...

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.

Cooling temperature will not below 70


controllers more than likely on a memory lockout... kill the power and take the batteries out of it... leave it for 60 seconds and try again... unfortunately you are probably going to have to replace the controller, sorry

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.

Solution #2 as above worked (thank you very much!) to get to the programming mode, but on mine keeping Function #13 on the default setting of "0" maintained the AIR.  Toggling the Temp button to "1" changed the system to conventional on/off at the programmed times.
