I'm guessing 30 amp RV service. You can't run both air's at the same time. Both A/C's draw too much current. Your EMS is not a true EMS. It is a "Load shedding system" It senses high amperage and removes an assigned load for a period of time until the required load gets down to the 30 amp level.I have an older Intellitec system (1999 Fleetwood Southwind "Class A"
Energy Management System will run front air conditioner by it sel
Rear air conditioner by itself
BUT NOT both together?????
