Since mine is a 2017, and heat pumps were new for 2017, I assumed it was for keeping your fluid tanks from freezing? The control for it is only in the back bedroom. I can't figure out these darn A/C units either, they stay on and i guess cycle between using the compressor or not using it. I noticed the back bedroom heater did not come on, unless the front heater was also on? That is why I am asking a silly question about the heat pumps, and what they are really going to do for me tonight when it is 20 degrees out or less?
