65 at night. 67/68 in the daytime. All the thermostats are programmed so if I get cold and kick up a few degrees it will go back to the settings eventually. We have let our master bedroom unit stay on 60 before. It was a little chilly for me.
Depends on how cold it is. If it’s cold like last night probably 67 because it’s going to run more. If it’s 45-50 range I may do 68 because it’s going to run less.
Same with AC the hotter it is the warmer I’ll run due to it running more
My late grandmother, no matter the time of year, would crank that thing UP. We’d stay the night and good lord it was always so hot and she’d still have on her sweater and talk about how drafty it was.
Usually 70 day & 66 night. In this weather 71 day & 68 night. Of course there no real meaningful comparison. 70 in one house with one thermostat can be very different from 70 in another house with another thermostat.
