Go to www.honeywell.com and search their data base for your model of thermostat. You wil need all the numbers of your thermostat to be able to search. Once you find it, download the installation manual.
Good Luck.

SOURCE: Replaced mercury thermostat w/Honeywell CT87K - doesn't work!

You need a specific thermostat for a Wall Furnace it is a Millivolt Thermostat and not a 24v standard thermostat....usually it will work anyway however if the powerpile (generator produces millivolts from the pilot light) is weak it may not be producing enough...or the Pilot light may be dirty and lazy...won't produce enough millivolts ...or you can have bad or dirty contacts or connections....or a combination of any of the above.....a 24v Thermostat and particularly a non-mercury thermostat has too much resistance in it for a millivolt system....as your Wall Furnace (other than the fan) runs on less than 1 volt

We have a Honeywell Digital thermosat. We just put brand new batteries in it and it is still showing lo battery.


on most of honeywell units if you pull the face of the thermostat off there is a reset button you can puch and reset try this.... if it does not have a reset remove the red power wire on the "r" terminal and if you have a wire hooked to the "c" terminal remove it at same time ///take batteries out prior to doing this and it will reset the program in thermostat... if the display comes back again with the lo battery the thermostat internally has a issue...good luck

I replaced the batteries in my Honeywell CT3300 and the "Bat Lo" message won't go away even with fresh batteries. Is there a reset button or something?


Per manual do this: System set to Off Remove batterie Replace IN REVERSE POLARITY POSITION or 5-10 seconds Put back in with CORRECT POLARITY Reprogram per sticker on back of thermostat. Done. Just did this myself and it's simple and effective! PaulHaven

Honeywell Chronotherm IV Plus requires frequent resetting.


Check to see if you have wires going to a C/C1 terminal. The older chronotherms used a transformer to supply 24 volts to power the clock. If in fact you do have these terminals, then I would suggest checking the output voltage on the transformer, (secondary (24v)side) to ensure it isn't close to dead. Hope this helps

Battery backup?


which model do you have ? the 8000/8001 or 8011 the set is different depending on your type of heating system. This model has a memory chip not a battery that saves your settings. So you could be looking at replacing the unit.
