Ok guys, I am hittng my head against the wall
I am working on a 1997 Holiday Rambler Endeavor on a Freightliner chassis for a couple of friends. About a month ago I tried turning on the ac units with the 1 thermostat that has 2 zones. Since the shore line wasnt heavy enough the fans kicked in, but when the compressors went to kick in i tripped the shore line breakers in the house garage. Which i was expecting. Once we got the generator started and power at full load the ac still will not kick in. I was told to upgrade to the 5 button thermostat after I tried to turn the furnace on and it wouldn't even come on when set at 99 degrees. So I spent the money and bought the new thermostat only to get the EE error code. I cleaned the connectors like a friend suggested, but now after some researching I am finding that there is a system "upgrade" that needs to be done in order to make the 5 button work on a 4 button system. Is this true? If so, can you please inform me what to replace and why? I am a skilled industrial maintenance tech by trade who is recently out of work and I am stumped!!!! Your informative help is appericated, and your technical help is really appericiated!!!
