Yes, the furnace just needs a standard CHEAP bi metal wall tstat to run the furnace. The link will show you just one tstat. At your Intellitec wall mounted Tstat system you just need to find 2 wires from the furnace. The furnace just has 2 wires that go to the Wall tstat system. One is 12 volts positive from the furnace and the other is the return of the 12 volts to the furnace. You will see a BUNCH of wires and a schematic would really help. Otherwise you can go to the furnace and see which and what color those 2 wires are and find the same at the Intellitec wall control. Yes, you could install AC wall tstats but that would involve running the wiring to each tstat. On a 25 year old motorhome that would be a waste of money. Just install new Roof tops with ceiling mount controls. Now, I know you are frustrated, but to blame a 25 year old system for your troubles is not normal. THINGS wear out and go bad. The Intellitec system was installed on hundreds of thousands of Motorhomes in the 90's and yes, they did have problems. But those problems happened after years of use. The problem now is, it is almost impossible to find replacement parts. From your description of your AC problems, you have 2 bad AC compressors after 25 years. Try replacing the upper units first and see if the Intellitec system starts to operate as designed. If not, then purchase the manual inside control kits. The New upper units do not come with the lower control kits, so, you will not have wasted any money. The Intellitec system is smart enough to detect HI amp draw like when you have a defective compressor and cause the system to not allow it to run. I would purchase the Upper and lower units with the understanding that if I did not need the Lower control I can bring them back for full refund. Doug
