As you may recall, a while back we had the generator auto-start unexpectedly. At first, I wondered if it was related to the bi-weekly auto-start/exercise on the new whole-house generator as they both occurred on the same morning. Subsequently, however, we have had the whole-house generator run through its bi-weekly exercise and the coach generator did not start.
Never did figure out why the coach auto-started as that function was set to "Off." I did, however, reset the maximum run time down to 120 minutes from the default 240. I also enabled and then disabled Auto-start. Don't know if that made any difference, but we have not had another unexplained auto-start.
The miracles of modern technology!
