Thanks for letting us help Aaron. Yes, since you are using the Single Zone Digital Thermostat # CM76RR currently, the Coleman-Mach WiFi Thermostat # CM46MR will work as an upgrade. The # CM46MR is designed for Coleman Mach single zone A/C and heat-pump systems and uses conventional 12V thermostat wiring. The # CM76RR is a digital wall thermostat, so you already have the control setup needed for the # CM46MR. You will just need to move the individual thermostat wires from the existing thermostat to the corresponding terminals on the # CM46MR.
Does your Coleman AC unit have a heat pump or do you use your existing thermostat to control a furnace?
