  • VPL24-210 transformer delivers 24 volts for reliable operation

Thermostat adapter with 24 VAC transformer

The PAC-US444CN-1 kit provides a thermostat adapter interface paired with a VPL24-210 24 VAC transformer. It converts control signals so a compatible thermostat can drive Mitsubishi HVAC equipment. Installers use it when integrating third-party temperature controls into a Mitsubishi system. The package includes both the adapter and the required low-voltage power supply.

Integration for third-party thermostat control

This kit suits technicians adding a non-Mitsubishi thermostat to an existing Mitsubishi heat-pump or air-conditioning installation. It is not intended for direct line-voltage switching or for systems that already include a factory-matched controller. Buyers needing a standalone thermostat or a different voltage supply should look at other options.
