How setting the thermostat from Heat for 65-80 degrees is different than Cool 65-80.

239 views

It has about roughly 80-85 degrees Fahrenheit where I live for the past few weeks. When I come home my fiance has the thermostat set for Heat with a range from 65-80, but if I turn the heat off it says the house is 80 degrees inside.

We have two animals who I know are very uncomfortable and I tell him that having Heat on from 65-80 is crazy. I say it needs to be set at Cool and if he wants a range then set it for Cool 65-80 (but I normally just set it to 72 anyway). He said since it’s a wide range of temperatures, even on the Heat setting, that it’s ok and it’s not as hot as I think it is.

How do I explain the difference properly? He thinks since the range is 65-80 that it would be the same be it Hot or Cool. If it matters, we live in a town home.

This is all dependent on the model of thermostat used. In a lot of systems the heat or cool just determines what effort the system will use to maintain that range. If you set it to heat it will only heat up if the temp drops below 65. If its on cool, it will only cool down if above 80. If you set it to auto/maintain it will kick on the heat or the a/c to stay in that range either way.

In a townhouse the main difference in feeling is due to the system having one thermostat and two floors (assuming you don’t have a dual zone setup). You are almost always going to have the issue of the 2nd floor being warmer than the first and not matching the temp on the thermostat. If the heat is used the 2nd floor will be much warmer, because it will heat the home until the 1st floor reaches that temp. If its being cooled the 2nd floor will remain somewhat warmer, but the bottom floor will be cooled to the set temp.
