Product features
Smart ME Controller is a remote controller designed to control Mitsubishi Electric’s air conditioning
units and also allows for the control of other manufacturer’s products connected via Mitsubishi
Electric’s AHC.
It can control up to sixteen indoor units and one AHC.
Smart ME Controller features such basic functions as operations and monitoring of air conditioning
units and schedule-control functions and is equipped with four built-in sensors (temperature,
humidity, occupancy, brightness), which enable an integrated control of the system, including the
humidifiers and ventilation units connected to the system via AHC, to help create comfortable
environment.
When the built-in occupancy sensor detects vacancy in a specific zone, the controller uses its
internal function to reduce energy-consumption.

Energy-save control with the use of the built-in occupancy sensor
Occupancy sensor
Brightness sensor
• Energy-save control will be performed when the occupancy sensor detects vacancy.
• When the occupancy sensor detects no human movement for a certain period of time, this will be
regarded as the vacancy.
• One of the following energy-save controls can be used at a time.
Energy-save control mode Control when vacancy is detected
Non-use –
