  • It worked
Took some doing by the hvac techs but they figured out what I couldn’t. I wired it up the same as my past thermostat but I had a unique electric heat situation for a larger house that took more work at the furnace.

  • 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

  • it's mnisrepresented
the product is misrepresented on the site. The description on the site says that the thermostate is nonprogramable while it is programmale. The model is not H721, it is 721, The display light has no option to stay longer or all the time, a person has to press the temp arrow up and down for the light to come on, the light stays on for only few seconds and turns off. A person would think that with large display an option would be there to turn the light on or to have it stay on longer than few minuts. ... show more
