It offers 3 input terminals for fan speed control: Auto, Medium, High, and custom auto. The CN105 connector allows HVAC thermostats and input/output controllers to control residential or commercial indoor units. Any system that can be controlled by the MHK1 controller model can now be controlled by a third-party HVAC thermostat or input/output controller. It works with conventional systems, but not heat pump control. The minimum terminals required are R, C, G, W1, Y1, and the preferred terminals are R, C, G, W1, W2, Y1, Y2. Line voltage thermostats are not compatible. It is compatible with almost all current indoor units offered by Mitsubishi Electric US. Only one third-party thermostat can connect to one thermostat interface to control a single indoor unit, even for the MXZ multi-zone system. It is compatible with the PAC-SE41TS Remote Temperature sensor and MAC-331F, but not with M-Net and MA Control. A 12 VDC power supply is required for the MAC-33IF. Please note that the PAC-US444CN-1 is compatible with Mitsubishi CITY-MULTI (Models after April 2012), M-Series, and P-Series Indoor Units. It has been tested with Nest, Honeywell, Lyric, and INNCOM thermostats with fan speed control. Supported thermostats include Nest, Honeywell, Lyric, and INNCOM with fan speed control. Only one thermostat interface is needed per indoor unit. It provides 3 input terminals for fan speed control: High, Medium, and Low.
