If you have a wall tstat, you will have the standard multiple wires coming from the roof top unit down to the wall tstat. YES, on Jayco's they use the one HOT(12 volt pos) blue wire from the furnace to power the 12 volt side of the Roof AC system. There are NO 120 tstat wires. The ONLY 120 is the roof top 120 voltage to run the unit. ALL controls to operate the roof top unit are 12 volt. This link will show you the wiring for a RVP/Coleman. Just remember, there are 2 blue wires from the furnace. ONE has 12 volts. THAT wire will be connected to the RED wire up at the AC unit. Doug
