NOTE
If the sensor switch is set to the remote controller side, but
no room temperature data is sent to the main unit for 10
minutes, the sensor is automatically switched to the indoor
unit side. As much as possible, install the remote controller
facing the unit.
5-2. Room Temperature Sensor Setting
The room temperature sensors are built into the indoor unit
and the wireless remote controller. Either of these room
temperature sensors can operate.
Heat pump models
The system is shipped from the factory set to the indoor unit
sensor. To switch to the remote controller sensor, press the
sensor switching button (* mark) on the rear of the remote
controller and check that A/C SENSOR on the LCD display
panel goes out.
Cooling only models
To switch to the remote controller sensor, press the A/C
SENSOR button on the remote controller and check that
the mark on the LCD display panel goes out. (Fig. 5-5).

Address Switches
• Heat pump models
If you are installing more than 1 indoor unit (up to 3) in the same room, it is necessary for you to assign each unit its own address
so they each can be operated by their remote controller.
Up to 3 indoor units can be controlled separately through the address switches. The operating control has the reception address
switch and the remote controller has transmission address switch. This function is utilised by matching the transmission and
reception address switches.
EX) 3 indoor units in 1 room
* Reception may be impossible if the remote controller is too far away. In this case, either use individual control or group control.
