    • Great thermostat
Size: 2.8 x 4.5 x 1.5 inches
So glad to find this "old school" type thermostat. The only thing that could make it better would be mercury in it. Also, the instructions were not the clearest but we figured it out. We repeatedly replace our digital thermostats...at least every year. So tired of them not functioning properly. It is amazing how efficiently and consistently our system is running now that this more basic thermostat is installed. I just ordered another for our upstairs unit. ... show more

    • I ordered wrong model for my tstat so cannot review
Size: 2.8 x 4.5 x 1.5 inches
It did come quickly and simple set up. I could not install it so I called a technician who explained that the newer tstats are not set in sequence to 30 yr old systems like mine. He said the color for the pins and the wires are off set, it is best to count the holes to get the right hole for each color. He did just that an my other tstat started working. I am keeping this one in case my other tstat ever goes out but I do not yet have any experience to say how ell it regulates. ... show more

    • Simple and Reliable Heating and Cooling Thermostat But It May Not Last
Size: 2.8 x 4.5 x 1.5 inches
Sometimes the tried and true simple device is the best! I replaced an electronic thermostat on my heating and cooling system that was aggravating the crap out of me. This is a simple electromechanical heating and cooling thermostat - It is NOT for heat pumps though. That requires a different type thermostat. Note that although this is a simple thermostat to operate its not for idiots. If you cycle your air conditioner on then off then back on without waiting the required 3 minutes you may trip the circuit breaker on the AC unit. It's not the fault of the thermostat if you do this - it's a user fault. Every AC manufacturer warns not to do that. Because this is an electro-mechanical thermostat it must be mounted level or the temperature setting may be affected. Get out your level - don't do it by eye. The good - simple & reliable operation. It just works. When you turn on the AC it turns on without delay. When you turn on the heat it turns on without delay. Mine seems to be well calibrated for temperature. Limitations - The thermostat wiring hookup is the old style where you wrap the end of the wire around the screws that are located at seemingly random places on the thermostat base and you have to flatten the thermostat wiring once connected so the the thermostat will connect. Update - Its a little over 2 years later. I have noticed that the thermostat seems to have developed a tendency to excessively stick "on" in either heating or cooling. It sometimes noticeably over heats or over cools by several degrees unless you tap the thermostat. I believe the problem is that the contacts are deteriorating and have some tendency to stick "on". This was precisely why the original mechanical heating and cooling thermostats migrated to using a little mercury capsule with the contacts in it instead of plain mechanical contacts. But modern sensitivities are to reduce or eliminate mercury in most items, so this is what you get. Instead of removing the internal plastic cover over the contacts and cleaning the contacts which might reduce the problem for a while, I replaced this thermostat with a Honeywell non-programable electronic thermostat. The electronic thermostats do not have this wear-out mechanism. This thermostat worked perfectly for over a year, but somewhere between then and just over two years I noticed this flaw in its operation. That causes me to reduce the rating. ... show more

    • I ordered two and neither worked
Size: 2.8 x 4.5 x 1.5 inches
I wanted a simple, non programmable thermostat and thought this a good choice. Wrong! After I set the first one up and connected the wires it wouldn’t work. I called tech support and was told to return it. I ordered a replacement, and had the same problem. Again, I was told it was defective and to return it. What a hassle! I ended up buying a lux mechanical which was cheaper, easy to set up, and worked immediately. ... show more
