2-12. Preparation for Test Run

2-12-1. Switching the temperature sensor
Temperature sensors are contained in the indoor unit and wireless remote controller. One or the other of the
temperature sensors is used for operation.
If (body sensor) appears on the LCD display of the wireless remote controller, then the indoor unit body
sensor is used for operation.
To switch to the remote controller sensor, open the remote controller cover and press the SENSOR button once.
The (body sensor) display disappears and the remote control sensor is used for operation.
NOTE
Even if the remote controller sensor is selected, the sensor will be automatically switched to the indoor unit body
sensor if no temperature signal has been received from the remote controller for 10 minutes.
Install the remote controller in a position where the signal can be reliably received by the unit.
When group control is engaged, be sure to use the body sensor.
2-12-2. Using the remote controller
Face the remote controller toward the receiver (on the main unit). (Fig. 2-9)
The signal can be received up to a distance of approximately 8 m. Use this distance as a guide.
This distance may vary somewhat depending on the battery capacity and other factors.
Be sure that there are no objects between the remote controller and the receiver which may block the signal.
The unit beeps when a signal is received correctly.
(For operation start only, the unit beeps twice.)
Do not drop, throw, or wash the remote controller.
Do not place the remote controller in locations exposed to direct sunlight
or nearby a stove.
