Coleman-Mach 9420A330 Programmable Multi-Zone Touch Thermostat

Coleman-Mach 9420A330 Programmable Multi-Zone Touch Thermostat — Coleman-Mach 9420A330 is a black, fully programmable multi-zone wall thermostat featuring a 4.3-inch touchscreen. The manufacturer identifies it for suitable Coleman-Mach cooling, heat-pump, electric heat-strip and furnace systems when paired with the correct control boxes; it is not the non-programmable thermostat described in some distributor feeds.

Compatibility and ordering
