9330-3411 Coleman Air Conditioner Ceiling Assembly Heat/Cool Thermostat Kit 

The 9330‑3411 is the OEM heat/cool mechanical thermostat kit used in Coleman‑Mach RV air conditioner ceiling assemblies. This kit provides manual temperature and mode control for non‑ducted and select ducted Coleman‑Mach rooftop units.

It replaces older cool‑only thermostats (9330‑340) and upgrades the ceiling assembly to full heat + cool functionality when paired with a compatible heat strip or heat‑pump‑enabled rooftop unit.

NOTE: When replacing COOL ONLY 9330-340 thermostat with a HEAT/COOL 9330-341 thermostat: terminal "1" or "H" is not used.
