I have done quite a bit of research into the auto gen start issue. What I have decided is that this will be fairly straightforward to implement in my situation.
The scenario for me is that I want to replace the standard Dimensions stepped sine wave interter with a pure sine wave model and also have auto gen start.
After pouring over the Horizon 40AD wiring diagrams, the Dimensions and Xantrex install manuals, and the auto gen start install directions; this seems to be doable by using most of the in-place Winny installed wiring.
The Onan Quiet 7500 uses 4 wires for remote start: negative, start, stop, and positive (or run indicator). These leads are accessable at the main control panel where the gen start switch is. I believe you can just tap into the existing switch assembly for the Xantrex autostart connections.
The Xantrex auto gen start has provisions for two thermostat inputs. I believe this could be as simple as wiring up another thermostat and putting it on the wall near the others
- when the temp in the coach gets to, say 85, it would trigger a gen start event.
I believe that if you are a cabaple DIY type around electrics you can do this yourself for just the cost of the Xantrex RS2000 (2000 watt pure sine wave inverter) and auto gen start module - probably 1500 bucks for the whole thing.
If anybody is interested in more details, I can post a more detailed discussion of this.
