  • good
It works. Just need professional help. Cause my compressor did not perform perfect as it does with the same kind of the AC units. So, in short look for compatibility.

  • It works
This particular thermostat works I've been through at least three of them that have purchased in other places this is the first one that actually works it's accurate easy to install and it works comes on goes off like it's supposed to. The only reason that I gave it four stars is that it shows a pilot light which means heat I guess.. I was confused usually there's a sun for heat not a flame means gas to me. It does have the snowflake for cold. other than that it is perfect you just set the temperature and it works. I'm happy ... show more

  • Adjustable temperature deadband that works correctly
This is a very versatile thermostat that will work in a variety of applications. I bought mine to use with an electric heatpump and wanted to be able to adjust the temperature span so that the heatpump would start and run for a longer cycle period. This is much easier and more efficient for the compressor on a heatpump. Many modern thermostates only allow only a CPH (cycles per hour) adjustment that will not limit the on-off times of your heating unit, since the thermostat will prioritize the temperature setting over CPH. This thermostat allows adjustment of the on and off temperature up to 2 degrees on the high and low temp (span) on either the AC or Heating side. It is accurate and so far has worked flawlessly, a bargain compared to the Honeywell thermostat it replaced. ... show more

  • Heagstat H721 Non-Programmable Heat Pump thermostat swap out was straight forward (read review)
The Heagstat H721 Non-Programmable Heat Pump Thermostat was a fairly easy swap out from a VIIVE TP-N-721. The plug on back plate was different. I killed the evaporator control voltage breaker. Then took a picture of the before thermostat wiring for color codes and connection point reference which was similar. Get help from an electrician if you don't know what you are doing electrically. This thermostat controls the compressor control relay, the reversing valve and the heat strips. I laid out the two thermostats documentation side by side for reference. Amazon delivered the thermostat the next day, so we did not have to go without too long. ... show more
