10-12. Preparation for Test Run
10-12-1. 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.
NOT E
●
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.
10-12-2. Using the remote controller
●
Face the remote controller toward the receiver (on the main
unit). (Fig. 10-9)
●
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.
