COLEMAN-MACH 9630A751|DIGITAL ZONE CONTROL BOX, HEAT PUMP, HEAT READY

9630A751 Coleman-Mach Digital Multi-Zone Control Box Assembly (Heat Pump Ready)

The Coleman-Mach 9630A751 is a highly sophisticated, multi-zone digital internal control module engineered to manage complex operational relays inside RV heat pump configurations. It coordinates low-voltage signals from advanced digital thermostats to cleanly dictate roof compressor, multi-speed fan, and reversing valve actions.

Product Features & Fitment

This heavy-duty metal control housing encloses premium electrical contactors engineered to balance high inductive startup currents, protecting your coach's electrical grid. It features built-in multi-zone communication logic, allowing a centralized wall controller to run multiple rooftop ACs or heat pumps independently across separate rooms or cabin zones. It also includes integrated leads to accept an optional slide-in auxiliary electric heat strip for specialized cold-weather redundancy.

The 9630A751 mounts directly within the return-air plenum channel of compatible Coleman-Mach ceiling assemblies. It is engineered explicitly for seamless pairing with modern Coleman-Mach multi-zone digital wall thermostats (such as models 9330A3341 and 9330A3351) and is universally compatible with Mach 8, Mach 15, and Roughneck series heat pumps. It will not interface with classic analog single-stage thermostats.
