This heat-ready control assembly works with multiple Coleman Mach models, from the Roughneck to the Mach 15, supporting both cooling and heating on non-ducted and laterally ducted systems. It accepts thermostat inputs and sensor signals to cycle your AC or furnace as needed. Installation typically takes about an hour, and the marine-grade electronics survive salty, humid environments indefinitely.
