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.

▌1 Occupancy Sensor
The occupancy sensor detects vacancy for energy-save
control.
▌2 Brightness Sensor
The brightness sensor detects the brightness of the room
for energy-save control.
▌3 Temperature & Humidity Sensor
The sensor detects the room temperature and the relative
humidity.

▌4 LED Indicator
The LED indicator indicates the operation status in different
colors.
The LED indicator lights up during normal operation, lights
off when units are stopped, and blinks when an error
occurs.
▌5 Touch panel & Backlit LCD
The touch panel shows the operation settings screen.
When the backlight is off, touching the panel turns the
backlight on, and it will stay lit for a predetermined period
of time.
▌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
Non-use
Control when vacancy is detected
–
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)

Safety precautions
• Thoroughly read the following safety precautions before using the unit.
• Observe these precautions carefully to ensure safety.
WARNING
Indicates a risk of death or serious injury.
CAUTION
Indicates a risk of serious injury or structural damage.
• After reading this manual, pass it on to the end user to retain for future reference.
• Keep this manual for future reference and refer to it as necessary. This manual should be made available
to those who repair or relocate the controller. Make sure that the manual is passed on to any future users.
General precautions
WARNING
Do not install the unit in a place where large
amounts of oil, steam, organic solvents, or
corrosive gases, such as sulfuric gas, are present
or where acidic/alkaline solutions or sprays
are used frequently. These substances can
compromise the performance of the unit or cause
certain components of the unit to corrode, which
can result in electric shock, malfunctions, smoke,
or fire.
To reduce the risk of shorting, current leakage,
electric shock, malfunctions, smoke, or fire, do
not wash the controller with water or any other
liquid.
To reduce the risk of electric shock, malfunctions,
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.
6
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.
Safety precautions
CAUTION
To reduce the risk of fire or explosion, do not
place flammable materials or use flammable
sprays around the controller.
To reduce the risk of electric shock or
malfunctions, do not touch the touch panel with a
pointy or sharp object.
To reduce the risk of damage to the controller, do
not directly spray insecticide or other flammable
sprays on the controller.
To reduce the risk of injury and electric shock,
avoid contact with sharp edges of certain parts.
To reduce the risk of environmental pollution,
consult an authorized agency for proper disposal
of remote controller.
To avoid injury from broken glass, do not apply
excessive force on the glass parts.
To reduce the risk of injury, wear protective gear
when working on the controller.
Relocation and repairs
WARNING
The controller should be repaired or moved only
by qualified personnel. Do not disassemble or
modify the controller.
Improper installation or repair may cause injury,
electric shock, or fire.
CAUTION
To reduce the risk of shorting, electric shock, fire,
or malfunction, do not touch the circuit board with
tools or with your hands, and do not allow dust to
accumulate on the circuit board.
Additional precautions
To avoid damage to the controller, use
appropriate tools to install, inspect, or repair the
controller.
This controller is designed for exclusive use with
the Building Management System by Mitsubishi
Electric. The use of this controller for with other
systems or for other purposes may cause
malfunctions.
To avoid damage to the controller, provide
protection against static electricity.
Properly dispose of the packing materials. Plastic
bags pose suffocation hazard to children.
To avoid damage to the controller, do not
overtighten the screws.
To avoid discoloration, do not use benzene,
thinner, or chemical rag to clean the controller.
To clean the controller, wipe with a soft cloth
soaked in water with mild detergent, wipe off the
detergent with a wet cloth, and wipe off water with
a dry cloth.

What the blinking mode name means
The mode name will blink when other indoor units in the same refrigerant system (connected to the
same outdoor unit) are already operated in a different mode. In this case, the rest of the unit in the
same group can only be operated in the same mode.
20
Basic operations
Auto (dual set point) mode:
When the operation mode is set to the Auto (dual set point) mode, two set temperatures
(one each for cooling and heating) can be set. Depending on the room temperature, indoor
unit will automatically operate in either the cooling or heating mode and keep the room
temperature within the preset range.
The set temperatures that are specified for the Cool/Dry mode and the Heat mode will be
used to automatically control the room temperature to stay within the set temperatures.
This mode is especially effective during the in-between seasons, when the temperature
difference between the highest and the lowest is large and both heating and cooling modes
are used within the same day.
