RV AC Control Boxes

The control box is the brain of a ducted Coleman-Mach system, mounted in the ceiling assembly between the wall thermostat and the unit. Cool-only, heat-ready, heat pump and digital zone packages are listed by part number. The thermostat must match the box: analog stats on the 8330 and 9330 packages, digital zone stats on the 9430 and 9630 boxes, the WiFi stat on 8330-752, 9330C755 or 9530A751 only.
