need help with 4 button to 5 buttom thermostat

[stinky62]

I installed a comfort control center model # 3109228.001, and two electric kits 3109226.005. On zone one both front and rear a/c works, but it will not go to heat or zone 2. thanks

Hello and . We are glad to have you join us here and we look forward to reading of your adventures and experiences. I am sure you will enjoy the website and forums.
A couple of questions. I presume by the thread title that the coach had a four button T'stat and you installed a new 5 button T'stat. Did you replace the control boards in both units as well? If you did, did you set the dip switches correctly on each board?
Zone one should control only the front air conditioner and a furnace or other heating appliance, not both, front and rear. I fear that you have not replaced the control boards and they must also be replaced as the two different T'stat are not interchangeable with replacing the old control board (or assembly) on both front and rear roof units. Looking for your reply so we can help you with this issue.
