8330A5221 Coleman Mach Carrier‑to‑Coleman A/C Control Conversion Kit

The Coleman Mach 8330A5221 is a factory‑engineered Carrier‑to‑Coleman control conversion kit designed to let you keep your existing Carrier remote‑style ceiling assembly while upgrading to a Coleman Mach rooftop air conditioner.

Carrier and Coleman Mach rooftop units use different control protocols, so without this kit the ceiling assembly cannot communicate with the new rooftop unit. The 8330A5221 solves that problem by providing the correct interface components and wiring, preserving your Carrier wireless remote functionality and eliminating the need to replace the ceiling box.

This kit is designed for cool‑only Carrier ceiling assemblies and includes all required mounting hardware.
