5. Selecting an installation site
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, wires 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) For connection to the indoor unit with an Auto descending panel, a place where people can check the Auto descending panel
operation of the indoor unit while they are operating the remote controller (Refer to the indoor unit Instructions Book for how to
operate Auto descending panel.)
(b) A flat surface
(c) A place where the remote controller can measure the accurate indoor temperature
Sensors to monitor indoor 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 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.)

(2) Installation space
Leave a space around the remote controller as shown in the figure at right, 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.
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 shorting, current leakage, electric shock,
malfunctions, smoke, or fire, do not install the controller in a place
exposed to water or in a condensing environment.
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).
