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
and the remote control sensor is used for operation.
N OT 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.
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.)
(See 2-15)
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.
