Coleman-Mach 9330C755 Heat-Ready RV A/C Control Package

Coleman-Mach 9330C755 is the heat-ready A/C control package for compatible Coleman-Mach ceiling assemblies. Airxcel's 2025 catalog distinguishes this package from the 8330-752 cool-only controller and identifies it for heat-ready air-conditioner configurations.

Choose the correct setup

For a wall-thermostat-controlled non-ducted RV installation, Coleman-Mach requires a compatible ceiling plenum, wall thermostat and control package in addition to the rooftop unit. A suitable heat-strip kit must be specified separately for the rooftop profile before electric heating is available. This control package alone does not provide a heater, furnace or heat pump.

Confirm the rooftop A/C model, ceiling assembly and control wiring against the Airxcel installation diagram. Do not substitute 9330C755 for the cool-only 8330-752—or for a dedicated heat-pump control package—based on a general “Mach 15” or “non-ducted” description alone.
