TRS Eco-drive + Iceland (Carrier)

Hello All!

I have a question. I have a problem with refrigeration unit TRS (this is brand of Carrier, now) which is mounted on truck.

This is Eco-drive generator + Iceland refrigeration unit. Cooling is working but, heating not work. Air fans turn on only for few secound and shut down. Anyone have more information about this system? I'm looking for circuit diagrams - any electrical informations about working of this system and how is steering.
