Works well for garage exhuast fan control
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.

Replaced the programmable digital one as it was screwing up. This was a great replacement.

Returned defective but replacement works fine
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.

Cheap but it works...for now
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.

Honeywell heat/cool thermostate
I tried a digital thermostat and hated, I had to get my phone to make it work and I dont carry my phone everywhere I go. This works well just set it and forget it. Love the manual availability.

Dont buy
Thermostat sticks on, wont turn off after starting the air conditioner. Had to switch back to my original thermostat. Threw it in the trash. Thats where it belongs. This didnt last one month.

I needed an all analog thermostat to turn on solar powered fans in a greenhouse type environment. This fit the bill perfectly. Super simple to set up with good instructions and it works flawlessly with my low voltage power wiring. The thermostat is wired to a Mosfet that is controlling power to solar powered fans fed directly from the panels with no batteries. The thermostat goes LOW when the temperature gets above the setpoint, Mosfet goes HIGH and the fans kick on immediately. The thermostat uses no power itself and needs no batteries so no worries about it not working one day. So far its withstood temperatures over 100 degrees Celsius with no reduction in performance. If you want a dead simple thermostat for controlling heating AND cooling this is your thermostat!

Simple and good. No dumb digital display that causes your furnace to go out just because you need a new battery. Simpler is better. Not everything needs a screen.
