Questions buyers ask
Questions buyers ask
Which thermostat do I need?
A 12 V heat pump stat. Coleman-Mach lists the 9420-391 WiFi, the 9420A382 digital and the 9630-3351 for this assembly. The Kate RV ducted heat pump kits use the 9420-391.
Do I need the 9530A751 control package too?
No. The heat pump control box is built into this assembly. The 9530A751 is for the plenum-only 9430-4552 non-ducted assemblies.
Will it run my cool-only air conditioner?
No. For a cool-only or heat-strip unit, use the 8430A635 or 8430A633 ChillGrille.
Ducted or non-ducted?
Ducted only. If cold air blows straight out of the air conditioner into the room, you need the 9630A715 or 9630-725 non-ducted heat pump assembly.

About Coleman-Mach
About Coleman-Mach
Coleman-Mach rooftop air conditioners are built by Airxcel in Wichita, Kansas, and have been since 1967. They are the original equipment on more RVs than any other brand, which is why the ceiling assemblies, controls and repair parts are still available for units twenty years old. Every unit carries the Coleman-Mach 2-year limited warranty; Kate RV handles the claim with Airxcel for you.
