1-3. Simple MA Remote Controller [PAC-YT53CRAU], cont.
• To monitor the accurate indoor temperature, install the remote controller away from direct
sunlight, heat sources, and the supply air outlet of the air conditioner.
• Install the remote controller in a location that allows the sensor to measure the representative
room temperature.
• Install the remote controller where no wires are routed around the temperature sensor on the
controller. (If wires are routed, the sensor cannot measure accurate indoor temperature.)
Important
Do not install the controller in a place where
the difference between the remote controller
surface temperature and the actual room
temperature will be great.
If the temperature difference is too high,
room temperature may not be adequately
controlled.
To reduce the risk of malfunctions, do not
install the controller in a place where water
or oil may come into contact with the
controller, or in a condensing or corrosive
environments.
(2) Installation space
Leave a space around the remote controller as shown in the figure shown below, regardless of
whether the controller is installed in the switch box or directly on the wall. Removing the remote
controller will not be easy with insufficient space.
Also, leave an operating space in front of the remote controller.

(3) Installation work
Controller can be installed either in the switch box or directly on the
wall. Perform the installation properly according to the installation
method.
1 Drill a hole in the wall.
Installation using a switch box
• Drill a hole in the wall, and install the switch box on the wall.
• Connect the switch box to the conduit tube.
Direct wall installation
• Drill a hole in the wall, and thread the cable through it.
2 Seal the cable access hole with putty
Installation using a switch box
• Seal the remote controller cable access hole at the
connection of switch box and conduit tube with putty.
To reduce the risk of electric shock, malfunctions, or fire, seal
the gap between the cables and cable access holes with putty.
Due to continuing improvement, above specification may be subject to change without notice.

To avoid deformation and malfunction, do
not install the remote controller in direct
sunlight or where the ambient temperature
may exceed 40ºC (104ºF) or drop below 0ºC
(32ºF).
Do not install the remote controller directly
onto electrically conductive objects such as
metal plate that has not been painted.
