Safety precautions

• 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

To reduce the risk of electric shock, malfunctions,
smoke or fire, do not operate the switches/buttons or
touch other electrical parts with wet hands.

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.

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.

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.

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 damage to the controller, do not
directly spray insecticide or other flammable sprays
on the controller.

To reduce the risk of environmental pollution, consult
an authorized agency for proper disposal of remote
controller.

To reduce the risk of electric shock or malfunctions,
do not touch the touch panel, switches, or buttons
with a pointy or sharp object.

5

To reduce the risk of injury and electric shock, avoid
contact with sharp edges of certain parts.

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.

Precautions for moving or repairing the controller

WARNING CAUTION

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.

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.

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.

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.

the control object group is stopped and the room temperature rises above the preset upper limit
temperature.
The Night setback function is not available if the operation and the temperature setting are performed
from the remote controller.
If the room temperature is measured by the air-conditioner's suction temperature sensor, the accurate
temperature may not be obtained when the air-conditioner is inactive or when the air is not clean. In
this case, switch the sensor to a remote sensor (PAC-SE40TSA/PAC-SE41TS-E) or a remote control
