Re: Dreaded EE code
I have a 2005 Monaco Diplomat PDQ Sorry I thought I posted that earlier. Terminals have been cleaned with alcohol. All good there. It seems P1 is the culprit. When I unplug p2 going to the rear unit I get EE code again. Plug back in and see zone 2 The only pin switch in zone 1 that is on is 5 for the furnace. My 12v goes to my front unit zone11.1KViews0likes0CommentsRe: Dreaded EE code
Update! I was able to get communication. I kept hearing clicking sound from control box about every six times resetting. I decided to plug thermostat in P2 plug, same clicking sound then plugged back into P1 and thermostat starting working. I have no idea why. Problem now is it will not see zone 1. Zone 2 works properly with furnace, ac and heat pump. No zone 1 as an option now. I really appreciate the help so far.1.1KViews0likes0CommentsRe: Dreaded EE code
I checked today. No unions. My board is accessed from underside of roof. It is an 8x8 box. I made another cable and unplugged p2 going to the rear unit. Same results. It does sound like a relay click sound on about every six times I try to reset. Here is a link to the photos I took of my cable and test as well as the unit. https://www.dropbox.com/sh/sdtpmld5z83tac7/AACx3RmLNwbn6QBylHc-1GTFa?dl=01.1KViews0likes0CommentsRe: Dreaded EE code
Thanks for the reply Doug! Both board's are new and the same result as with the old boards. I take it the unions you are talking about are the p1 and p2 jacks on the control board? If so they are new and clean. You do mention beige in color mine are black. I did make my own cables and checked the wiring 4 times and it is correct to the wiring diagram. Also checked with a cable tester and all reads good. I'm stumped. I have a 2005 Monaco Diplomat.1.1KViews0likes0CommentsDreaded EE code
Hello all, I need help with Ac. I have the 5 button duotherm. I have replaced the thermostat, one communication cable that was bad and the control board. Actually two of them. I have tested both communication cables the one going to front ac and the one to the back ac. Both are good and wired correctly. My units are the older penguin heat pumps. What am I missing turn thermostat off press the two buttons get the FF then release and get EE. Have checked the 12v and 110v and all good. All duotherm said in email is you have communication error. I Know that but why? Help! Thanks in advanced!4.8KViews0likes15Comments
