9430-5501 Coleman Mach Bluetooth Thermostat Gateway & Control Box

The Coleman‑Mach 9430‑5501 is the Bluetooth / RV‑C Gateway & Control Box that sits between your Bluetooth wall thermostat and the rooftop A/C or heat pump. It’s the communication brain of the entire Coleman‑Mach Bluetooth system — and your shopping results confirm that clearly.

This assembly combines the gateway network module with the unit control box, allowing Bluetooth thermostats to communicate wirelessly with the rooftop unit. If your thermostat lights up but the A/C or heat pump does nothing, this gateway/control box is the component that typically fails.
