Is that the little 3" square 'single zone'
Controls one heater one A/C unit
My uncle has that in his new class B, (traded off his Thor Serrano)
Seems to be a troublesome design, and it has a slow response
Try changing mode to heat , run the temp up to something like 80 or 90(for testing)
Then set to ON do not set to auto
Then wait , could take two minutes or more to come on
There was another thread few days ago, somebody wanted to replace it
Options are limited , it's a proprietary digital system
I saw a schematic posted someplace of the control box wiring
Maybe it was from Chris
