My heat pump shuts off when the CoP goes down to 1. I still have my electric baseboards from before so they kick in when the heat pump kicks out. Can't all heat pumps be configured to shut off like mine does?

I live near Maine and have similar weather, and typically the heat pump only goes out for 3 to 5 nights and 1 or 2 days over the winter. The extra cost of a few days of EBB use is pretty minor compared to the savings throughout the other 362 days of the year.
