8. Something seems a bit strange...

A heat pump is going to work very well when it's not very cold outside. The smaller the heat differential between inside and outside, the better the performance will be. But when it's extremely cold outside, the heat pump may not be able to deliver as much heat as needed in order to keep your home warm, so there's often an option to have direct electric heating, which I suspect is the "emergency heating"

From your understanding, what is the source of the heat when it is not on "emergency heat"?

Otherwise, I suspect that you got some bad instructions, because I don't think there's any circumstances where using a heat pump like that would make sense for heating.
