ProHeat Gen 4 Operation. Lost power, heating, and AC.

I used the APU last night, took a nap, got up and shut it off. I'm needing it again and all its doing is charging the batteries. I checked the Belt, the water lines are hot but on the display I see a power symbol with a / across it. Anyone have one of these APUs? Since I got the truck its only been press the button, heating or cool and it would work. now all its doing is charging the batteries. Real Aggervating. There are no fault codes displayed. I don't even know how to turn the power back on. any help is greatly appreciated.

Found the problem. If anyone ever needs the APU manual there it is. The breaker inside the APU under the generator tripped.
