This remote controller is for the wall installation. It can be installed either in the switch box or directly
on the wall. When performing direct wall installation, cables can be thread through either back or top
of the remote controller.
(1) Selecting an installation site
Install the remote controller (switch box) on the site where the following conditions are met.
(a) A flat surface
(b) A place where the remote controller can measure the accurate room temperature and humidity
Sensors to monitor the room temperature are on the indoor unit and on the remote controller.
When the room temperature is monitored with the sensor on the remote controller, the main
remote controller monitors the room temperature. When using the sensor on the remote controller,
follow the instructions below.
• To monitor the accurate room temperature and humidity, 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 and humidity.
• Install the remote controller where no wires are routed around the temperature sensor on the
controller or where no obstacles block the air inlet, otherwise the sensor cannot measure accurate
room temperature and humidity.
• After the controller has been exposed to high humidity (above 80%RH) for 60 hours, the humidity
detection value will be offset by 3%RH.
When the ambient humidity drops below 80%RH, the offset will be gradually cancelled.
• Do not install the controller where it is exposed to high concentration of acid, alkaline, or volatile
organic compounds.
• If exposed to cigarette smoke for a long time, the humidity detection value will be offset.
(c) Install the remote controller where occupancy and brightness can be properly detected.
The remote controller has an occupancy sensor and a brightness sensor.
Each sensor has a sensor-detection zone.
• Install the remote controller where the coverage area covers the appropriate area in the room.
The maximum distance the sensor can detect occupancy is approximately 10 m (32 ft).
: Detection area
* As an inherent characteristic of the occupancy sensor, it is more sensitive to movements across
the area indicated by ■than to movements straight toward the sensor.

Occupancy sensor detects occupancy based on the temperature difference between the occupant
and its surroundings.
To be precise, to enhance the sensitivity of the sensor to occupant movements, the occupancy
sensor is designed to detect the changes in the amount of infrared light emitted from an object in
the detection zone, including human bodies.
The occupancy sensor will not detect occupancy if no movements exist.
The sensor also becomes less sensitive to occupancy when the temperature difference between
the occupant and its surroundings is small.
• Select the installation location carefully to avoid false detection.
Factors that contribute to false detection by the occupancy sensor
• Direct sunlight to the remote controller
• Supply air directed straight toward the remote controller
• Fireplace in the detection zone
• Portable heater (e.g., oscillating electric heater) in the detection zone
• Excessive vibrations or large impact inflicted on the remote controller
• Strong electrical noise
• Movements of small animals, such as cats and dogs
Handling precautions
• Keep the lens scratch-free.
• Do not place adhesive tape or labels over the lens.
• Use a soft cloth to clean the lens.

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 avoid deformation and malfunction, do
not install the remote controller in direct
sunlight, where the ambient temperature
may rise above 40ºC (104°F) or drop below
0ºC (32°F), or where the relative humidity
may rise above 90% or drops below 20%.
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.
Do not install the remote controller directly
onto electrically conductive objects such as
metal plate that has not been painted.
To use the Energy Saving Assist function in
a system with both main and sub remote
controllers, activate the function only on the
remote controller whose coverage area is
the largest.
