@JasonStiff @rpmik My system has a heat pump that it is connected to a thermostat that will turn on the heat or air conditioning depending on what is needed to keep the temperature within a specified range. This time of year we have a few days where the heat comes on in the morning and the air conditioning comes on in the afternoon. Yesterday morning the heat almost came on, but I adjusted it by 2 degrees so it wouldn't. I live in north central Washington state.
