Replacing a Coleman Mach thermostat with a Hunter 42999B?


Our current camper came with a Coleman Mach analog thermostat (for both hot/cold). I have a Hunter 42999B digital thermostat that came out of our previous trailer. I would like to replace the Coleman with the Hunter, but have not been able to find the exact wiring combo for this combination. I have found posts that say you don't need this or that wire, but if the wires on the Coleman were used (6 wires) for something I would like to know where on the Hunter (5 wire). Coleman uses R-red, B-blue, Y-yellow, GH-green, GL-gray, W-white. Hunter uses G, W, Y, Rh, Rc. Has anyone done this same swap, and if so what wire combinations worked for you? Thanks!
