Heat pump Thermostat
With my heat pumps, I rarely change the thermostat settings. Except for one of "those special nights" when it is bumped up 4 or 5 degrees for a couple of hours.
It appears that once the auxiliary heat is engaged, it stays that way until the thermostat is fully satisfied. For example, raising the thermostat just one degree does not normally engage the auxiliary heat. But raising it 4 degrees soon starts the auxiliary and it stays in that mode even when the temperature rises to within 1 degree of the increased setting. Are there any thermostats that do not operate this way?
