Looking ahead to cooler weather this winter, and a question.
We have a second home in Southern Delaware that has a 2stage Goodman heat pump with electric backup. This place is mostly vacant in the winter so we turn down the heat while not there. We visit for a week or so every 2 or 3 weeks.
We can control the thermostat remotely and there is an outside temperature sensor that locks out the electric strips above 25*
I understand that when occupied we should keep the house temperature relatively constant temperature to maximize efficiency.
So the question, is there any minimum setback temperature for the house when we are not there to avoid equipment damage, or other issues? Recovery time is not an issue as I can start warming up the place remotely.
