I set my AC several degrees colder than the AGS to be sure that I get the maximum benifit of running the generator. I am trying to keep my pets cool. If you have two ACs you may want to be sure that the generator will start both. I have had issues with mine so for now I just leave on AC enabled while the RV is unattended. If both ACs are needed I just leave the generator on manually. Keep in mind that if you touch the manual controls at all the AGS function is turned off and has to be reset(at least it does on mine).
