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 switches/buttons 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.

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.

4

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.

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.

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 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.

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.

To avoid damage to the controller, provide protection
against static electricity.

Notes on setback operation

• The setback mode can be set from this remote controller only in the systems that have the following type of units:

· Unit that features simultaneous cooling and heating functions: PURY/PQRY series

· Unit that features simultaneous cooling and heating functions with the use of external heaters
(Field supply): PUHY series with external heater

Depending on the production month, the simultaneous cooling and heating function is limited on some PUHY units.
For the availability of this function, contact a local sales representative.

Type of units other than the types above cannot be operated in the setback mode. In this case, set “No” in the
Setback mode setting. Refer to the Initial Setting Manual for details about Setback mode setting.

For PUHY series of units which do not have simultaneous cooling and heating function with the use of external
heaters, make sure to use TC-24A for the setback mode.
When using both TC-24A and PAR-30MAAU in a system, make a setting for the setback function only from one of
them. Do not make a setting from both of them.

• When the setback operation is performed on the cooling-only units, the upper/lower limit temperature can be set, but
only the upper limit temperature is controlled in the operation.

• If the Operation mode changeover limit is set from the system controller, the Setback mode will be canceled, and the
Fan mode will be set.

• If the Maintenance or Service function has started, the Setback operation will not switch the operation mode, and the
operation mode will remain the same as the one before the Maintenance or Service function has started.

The icon is scheduled to appear after a certain duration of operation, based on the premise that
the indoor units are installed in a space with ordinary air quality. Depending on the air quality, the
filter may require more frequent cleaning.
