I bought a ct87n thermostat and can't get it to work

the manuel didn't say how to hook this up if you only have 2 wires so I went to the on line manuel. It said to hook the wires to R & W . It still doesn't work. I got a second thermostat thinking the first one was defective but it still doesn't work. I am using this on a gas fireplace . How can I make this work ?

You may have blown the transformer at the furnace or a fuse at the furnace. You need to check voltage at the wires, you should have 24v if not you may need a technician to come out if you are not familiar with furnaces

does this run in electric?

I had an old mercury one and the gas co. took it out and replaces it with a digital one and when my lights go out I don't have heat. I want one that works without elect. So I can be warm even with no lights. Help please. I have had this a few years and I live on a slab so it gets cold fast and I worry about the pipes freezing in the winter without heat.

Generally if you lose power your heating system isn't going to work, battery or not

I appreciate the fact that it is straight forward and non-complicated. I cannot stand programmable thermostats for many reasons I wont bother to mention. Just glad to have a simple version that does the job without all the fuss.

No it does not meet my expectations because the room temperature it actually holds differs from the desired temperature we set by over 5 degrees. Also the difference between the two does not seem to be a simple constant adder.

Rated 5 out of 5 by from A Beautiful Thing After years of hassle with 3 different digital units, 2 in the house, 1 in the garage, I have replaced both with the old reliable Honeywell manual models, what a relief ! Easy to install, no batteries, no programming, no issues if whole house power goes down briefly, just adjust manually as needed with a flick of the wrist. As a DIY guy I do wish they made an old folks model, just a half inch or so larger for easier installation in homes with older wiring and a bit larger lettering, all in all though this product is a dream and the price is right !

AS WE ARE AN OLDER RETIRED COUPLE ,WE DONOT NEED A CLOCK OR PROGRAMMING AS WE ARE HERE AND RAISE OR LOWER THE TEMPERATURE AS NEEDED . THE ONE THIS REPLACED,WAS TOO SENSITIVE AND WOULD CYCLE EVERY FEW MINUTES- THE VERY SHORT CYCLING IS VERY ENERGY INEFFICIENT. THE HONEYWELL HAS TWO SWITCHES THAT ALLOW DIFFERENT RUNNING CYCLES-THE PROBLEM WAS FINALLY SOLVED- DISPITE THE FACT THAT THE NEW FURNACE IS OVER SIZED AND OVER FIRED IT ALSO REGULATES THE COOLING SYSTEM VERY WELL IT IS A SIMPLE BUT EXCELLENT PRODUCT.

I read some reviews panning the lack of adjustment for the thermometer, and the inability to change the 10-year lithium battery. I just found a way to do both. On the back of the thermostat (switch base removed) there are three plastic tabs that can be moved with a key to remove the front plate. On the back of the front plate is a small hub allowing adjustment of the thermometer. You can see the lithium battery below the printed circuit board on the base--replacement will require a few more plastic snaps to remove the circuit board. I could not find a way to calibrate the thermostat, and there's no differential adjustment, both of which I like. Honeywell says there are infrared sensors looking at several different areas of the room and averaging those readings, so calibration is not needed. There are probably some rooms with a thermal mass (masonry floor or walls) and large areas of glass where these won't work well.
