(4) Total length of remote controller wiring
• The maximum total length is 500 m (1640 ft) when one remote controller is connected, and 200 m
(656 ft) when two remote controllers are connected.
CAUTION
- The wiring cannot be connected to TB5 of the indoor unit of the same
- Remote controllers cannot be wired together. Only one wire can be connected
- When connecting to TB5, connect up to two wires of the same size to one

How To Install
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 built-in sensor on
the 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.)
Important
■
Discrepancy between the indoor temperature measured at the wall and the actual
indoor temperature may occur.
If the following conditions are met, the use of the temperature sensor on the indoor unit is
recommended.
• Supply air does not reach to the wall easily where the remote controller is installed due to
improper airflow distribution.
• There is a great discrepancy between the wall temperature and the actual indoor
temperature.
• The back side of the wall is directly exposed to the outside air.
Note: When temperature changes rapidly, the temperature may not be detected accurately.
