Which is a better way to program a thermostat? Example: +1 over set temp (set at 81, turns on at 82, shuts off at 80) or just have it turn on at 81 and shut off at 80.

I set mine at 80 so that it clicks on at 81 and shuts off at 79.

But unless the ambient is over a 100 I don't run it at all.

Mine clicks on at 1° above, and clicks off 1° under. Heat works the same way, just in reverse.

Speaking of which, it’s 67F in my house and I’m freezing. Y’all send some of that dry heat my way.

I usually set the span to max. This minimizes short-cycling, allows the HVAC to run more efficiently, and more effectively moves air around the spaces.

I've found that 1°F / .5°C gives the most uniform temperature. I tried 3°F above and below, and that made it alternating cold and hot.


I use the overseas manual to choose my viscosity.
