I have a new 2010 MS and discovered that the EMS wiring was mis wired. At the t-stat the living room a/c heat pump is A/C 1 and the bedroom A/C 2. At the EMS, they were switched. This is an issue when plugged into 30 amp service and the EMS must reduce the load which will leave you with only a bedroom a/c. I'm still waiting to get mine fixed but it should be an easy fix. Hopefully :)

Our unit was one of the first that got this new feature. It was shutting down our Sat Dome and receiver. Made a call to Mfg and they informed us that DRV knew there was an issue with wiring.
According to DRV, it was labeled wrong. But according to another MS owner, it was wired wrong, too. We haven't gotten ours checked yet, but are hoping to very soon.
