9630-3523 Coleman MACH Bluetooth Thermostat Heat Pump Multiple 

The 9630‑3523 Coleman‑Mach Bluetooth Thermostat (Heat Pump, Multi‑Unit Compatible) is the OEM smart thermostat designed for modern Coleman‑Mach HVAC systems that support heat pumps and multiple air conditioners/furnaces. It replaces traditional wall thermostats with a Bluetooth‑enabled control head, allowing users to manage temperature, fan modes, and system functions directly from a paired mobile device. This model is engineered for RVs equipped with Coleman‑Mach Bluetooth‑ready control boxes and offers a cleaner interface, easier setup, and more flexible placement than older wired thermostats.

System Role and Capabilities

This thermostat serves as the central control point for compatible Coleman‑Mach heat pump systems and multi‑zone configurations. It communicates wirelessly with the control box, enabling:

• Heat pump and electric heat strip operation (depending on installed equipment)

• Multi‑unit coordination across multiple rooftop A/Cs

• Furnace integration when paired with the correct control box

• Bluetooth app control for temperature, mode, and fan settings

• Cleaner installation with fewer wall‑run wires

Its Bluetooth interface is especially useful in RVs where thermostat placement is limited or where users prefer mobile‑based control.
