CT31A1003 Heat/Cool Non-Programmable Thermostat, Beige

Works as advertised works on heating or cooling. Installed one on my mother's air conditioner and 1 in my garage for my overhead heater , they work very well.

Excellent choice for older HVAC systems with no 'C' wire. Easy install with provided instructions and included parts. Works great! This is a thermostat that does not include a built-in thermometer display, so if you want that try a different model.

I am using this thermostat to control a 12VDC relay which is controlling a high voltage/current relay in the fan circuit. Has been working fine so far.

I have used this thermostat for several years and have found it trouble-free. After trying out a Nest thermostat and not liking it, I purchased another one. Unfortunately, it was defective, and Honeywell didn't seem to support this model. Frustrated, I initiated a return, and Amazon promptly sent me another one. I compared the two, and I could clearly see the problem, which was obviously a result of poor quality control. The replacement works perfectly and I expect many years of use from it. I am a licensed electrician.

Great

Ok

I'm a HVAC contractor, this is not a good quality thermostat. I had to make a jumper inside the terminals in order to make it work.

This is the most basic thermostat on the market, and I bought it to replace the very same model that the landlord had in our condo. I would have waited for the landlord to replace it, but at this cheap price it was faster and easier for me to take care of it myself. The problem with the old one was that the relay had stiffened up with time and we had to turn the temperature way above what we really wanted to get it to even come on, then the condo would get way too hot because of the high temperature setting. That means that, to avoid waking up in the middle of the night in a pool of sweat, we basically didn't use the heat at night. The new one works as it should, but because we already had a problem with the same model I am not convinced of its longevity. If this were my house and not a rental, I would put in something better.
