I'm trying to install or replace the Coleman-Mach with a honeywell RTH3100C thermostat and the wire colors DON'T match up. Has anyone done this and if so can you tell me which color goes where. The RTH3100C has terminals as follows. E Aux Y G O L R B C and the Mach wires are. 1- Gry (freeze & Exclusion Relay 2-Red (+12vdc) 3-Blu -(12vdc) 5-Yel (cooling Comp. #1) 6-Org (cooling Comp. #2) 7-Blk (Fan Hi) 8-Wht (heat pump) 9-Pur (Fan low) Any help on this would be appreciated Many Thanks CharWan
