What happens when you try to run the heat pump? Has the heat pump ever worked that you know of?
BTW - on our Legacy units the "EMS" (at least how they market it) is in the automatic transfer switch and it simply monitors the incoming power to the rig and shuts it down if there are problems. Has no bearing on your heat pump situation.
