There are many possible reasons the heat pump might not be turning on, do a 'soft reset' of the system by turning the power off to it, then back on.
Tell me please about how old the heat pump is, and a lot about your technical skill sets and instruments if any on hand.
I need to know which direction you are from the center of the nearest city, and what the dealer has to say about the situation.
We can go from there.
