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 –
ON/OFF The unit will be turned off.
Set temperature offset The set temperature will be offset.
Fan speed down The fan speed will be set to “Low.”
Thermo-off The unit will go into the Thermo-off state.
• Energy-save control can be stopped according to the brightness level detected by the brightness
sensor. (Example: While the occupants are sleeping at night)

smoke or fire, do not operate the touch panel or
touch other electrical parts with wet hands.
When disinfecting the unit using alcohol, ventilate
the room adequately. The fumes of the alcohol
around the unit may cause a fire or explosion
when the unit is turned on.
To reduce the risk of injury or electric shock,
before spraying a chemical around the controller,
stop the operation and cover the controller.
To reduce the risk of injury or electric shock, stop
the operation and switch off the power supply
before cleaning, maintaining, or inspecting the
controller.
If any abnormality (e.g., burning smell) is noticed,
stop the operation, turn off the power switch, and
consult your dealer. Continued use of the product
may result in electric shock, malfunctions, or fire.
Properly install all required covers to keep
moisture and dust out of the controller. Dust
accumulation and water can cause electric shock,
smoke, or fire.
