RVP has never found a solution for the 00 problem. They have installed filters and other redesigns, but never found a sure cure. This is one reason Tiffin dropped the ZC in their Motorhomes and went
to each roof unit having its own wall tstat. Doug
Problem is you have to replace each TOP RVP control module and then hope that there are enough tstat wires to control 2 tstats. You can mount the 2 new tstats next to each other because the Temp sensors are installed both front and rear. Any possible extra wiring can be run thru the ceiling ductwork.You need to call RVP and see if the existing roof top control modules will work with the new separate tstats.Doug
here is the install and wiring manual for the ZC tstat system
