PAC-US445CN-1 thermostat interface enables the use of a third-party thermostat to control your Mitsubishi Electric indoor units. It provides 3 input terminals to control fan Speed: Auto, Medium, High, and custom auto. The Thermostat Interface allows HVAC thermostats and input/output controllers to control either residential or commercial indoor units through its CN105 and CNH02 connector. Any system that can be controlled by the MHK1/MHK2 controller model, can now be controlled by a third-party HVAC thermostat or input/output controller.

Works with conventional systems, NOT heat pump control. Minimum Terminals: R, C, G, W1, Y1. Preferred Terminals: R, C, G, W1, W2, Y1, Y2. Line Voltage Thermostats will not work. Compatible with almost all current indoor units offered by Mitsubishi Electric US. Only 1 third party thermostat connects to 1 thermostat interface to control only one indoor unit even for MXZ multi-zone system. Compatible with PAC-SE41TS Remote Temperature sensor & MAC-331F but M-Net & MA Control are not supported, and you will need 12 VDC power supply for MAC-33IF.
