Simple to follow directions and very straight forward. Honestly, I am a dyslexic and it only took me 15 minutes to install it.

Answer: 
It only has a few color coded wires to hook up and screw it to the wall. So if you already have the colored wires coming out of your wall or an old thermostat, I would bet you could install it with in a sort time.

Yes, you can install it yourself so long as you have proper training and/or experience in electrical theory and follow the wiring diagram specifications as laid out in the book that came with it.
NOTE: if you were to remove the original thermostat without turning things off at the breaker panel, you could be potentially handling a live 220V line.

In my area, there are some professionals who don't charge as much as usual and will instead supervise you and direct your actions as needed. (Basically, if they have to touch it, they charge more.)

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 ?

Answer: 
Based on your description, I'm pretty sure that this is NOT the product which you need. While this can support a gas-based system, it is intended to handle a typical 220-240V system. If you only have a red and a white, that sounds more like it's intended for a switch or rheostat of some kind. I would highly recommend you hire an electrician to be certain of what you need, if at least for a consultation. Read More

Answer: 
You have the wrong thermostat for a two wire heating appliance. Take your model CT87N back and exchange it for the model CT87K which is a similar thermostat in looks and operation except that it is designed for a two wire appliance like your fireplace burner (and the good news is that you will get a few dollars back during the exchange). Good luck.

Answer: 
Hi Randy,
The CT87N thermostat is rated for 24Vac heating and cooling systems. We recommend that you verify the voltage, which can be located on your old themostat or existing equipment manuals. If you find that your system is milivolt (750 MV) We recommend the RTH110 series of thermostats, as this thermostat works on 24 volt or 750 mV systems.
Thanks,
Honeywell Support Team.

Answer: 
You may have to supply an external voltage to it since you are not using it in a standard furnace mode. Power it with a transformer with the right voltage and see if it works for you then.

Answer: 
Sorry, no. This is a solid state device and needs no leveling. There are scores of complaints on the Internet about this model. Maybe a call to Honeywell customer service would help, but I would demand a refund and get a basic digital read-out, non-programmable unit for simplicity.

Answer: 
Make sure the hole in the wall where the wires are coming out of the wall is plugged with insulation. A draft in the wall can have a direct affect on the thermostat. If that doesn't take care of your issue, please reach our Honeywell Tech Support group at 800-468-1502 for further troubleshooting of this thermostat.

Rated 4.0 out of 5 by 57 reviewers.
Rated 5.0 out of 5.0 by 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 ! October 9, 2016
Rated 5.0 out of 5.0 by Tried and true Originally installed a programmable with the usual good intentions only to realize the Honeywell in my case is the best. Setting it manually is easier than the frustration of programming, finding the instructions to change programs, changing batteries, etc. October 4, 2016
Rated 1.0 out of 5.0 by Product did not match the picture I needed a heat/off/cool switch and a fan continuous/ auto switch as pictured. The product delivered was without these switches, and there was not one in the store. I would NOT recommend your store or site October 4, 2016
Rated 1.0 out of 5.0 by No longer adjustable Honeywell has let us down. Wanted to replace an older Honeywell thermostat with a new one, expected the same quality. The thermostat can not be adjusted by homeowner, the company and factory have decided the variance with a set degree. This is so unbelievable, I have 2 older thermostat that allow me to adjust the time for the furnace to start and stop around the temperature I have set. I don't like a big variance in temperature and home is soundly insulated so a big variance is uncomfortable. July 26, 2016
Rated 2.0 out of 5.0 by Not what I expect from Honeywell I purchased 3 of these before I got one that worked, but it isn't working properly either. Temp in house shows 72 when i have it set at 76 have to set it at over 80 to get temp up slightly and it will very at times and what I mean is same setting but it will be hot in the house at times & too cold at times. WOULD NOT RECOMMEND THIS UNIT!!!!!! August 11, 2016
Rated 5.0 out of 5.0 by happy find .... ...it was much like the old one i had to replace....as i said above...i am happy that i found it... August 16, 2016
Rated 5.0 out of 5.0 by best purchase ever the install went with no problems at all. work like a charm August 16, 2016
Rated 1.0 out of 5.0 by Bought 4 defective thermostats before I got a working one. Bought 4 before I got one that worked. Paid HVAC Co. to tell me it was the thermostat and not the furnace. He replaced with digital thermostat. May 11, 2016
