Mitsubishi Electric introduced the most advanced Thermostat Interface for ductless systems
The Thermostat Interface PAC-US444CN-1 allows conventional HVAC thermostats or other on/off controllers to control commercial City-Multi and residential M-Series indoor units. The device uses a patent pending algorithm to vary the INVERTER-driven compressor capacity in order to save energy. It accomplishes this by setting up and wiring a thermostat for a conventional system control with two stages of heating and cooling.
“This is the most advanced Thermostat Interface for ductless systems in the industry” claims the Mitsubishi Electric’ bulletin. “Third party thermostats or on/off controllers can control the indoor unit’s fan speed to three different levels: high, medium, and low.”
The Thermostat Interface for ductless systems offers a host of advanced features which allow for more comfort and control, including:
- Adjustable Delayed Off feature, that provides additional comfort by extending the run time of the indoor unit, after the thermostat reaches set point.
- Fan speed that can be adjusted to provide the maximum level of comfort by selecting Comfort Auto, compared to the more efficient Auto default setting, with more advanced settings available
Compatibility charts are available on the product launch guide and on here. The list price is currently available in the CITY MULTI® and M- and P-Series price lists.

Does this thermostat interface interferes with WiFi signal in a home? Anyone had experience? It seems like a new thing in town, anyone have tried it? The reason I am asking is that I have got a similar thing that starts my coffeemaker over the internet, but it screws up my WiFi signal. Any help is appreciated

Hi Ioanne, this thermostat interface is for Mitsubishi ductless mini split system, cannot be connected to Fujitsu, Daikin, Panasonic, Carrier, Train, Goodman, Pioneer, and no other brands! Get Mitsubishi Mr. Slim first, and then will fit the thermostat interface. Truly, why would you ask such question if it does not make any sense at all, at least to me, even though I am a truck driver, not a licensed HVAC technician like you

Hello, is this a separate part, like a module, and what it takes to install it? I am a licensed HVAC technician, long time in the industry, but this is new to me. The whole ductless concept is new in our area, so I am trying to learn. I know these systems are more than 30 years in Asia and Europe, but in our area it is new. Please explain how to work this thermostat interface in regular central system

I checked compatibility chart on MyLinkDrive, looks good, I think I can use it on my 5-zone residential system. This is M-series system, right? Any tips and tricks I should know about before I proceed with installation?
