5.1. Main zone remote controller
5.1.1. Installing the zone remote controller
This remote controller is for the wall installation. It can be installed either on a
mounting block or directly on the wall. When performing direct wall installation, ca-
bles can be thread through either back or top of the remote controller.
(1) Selecting an installation site
Install the remote controller 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 tempera-
ture
Sensors to monitor the room temperature on the indoor unit and on the remote
controller.
• To monitor the accurate room temperature, install the remote controller away
from direct sunlight, heat sources, and the supply air outlet of the air condi-
tioner.
• 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 or where no obstacles block the air inlet, otherwise
the sensor cannot measure accurate room temperature.
• Do not install the controller where it is exposed to high concentration of acid,
alkaline, or volatile organic compounds.
(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 area.
• 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).

Note: As an inherent characteristic of the occupancy sensor, it is more sensi-
tive to movements across the area indicated by

than to movements
straight toward the sensor.
