Switching the Room Temperature Sensors
Room temperature sensors are contained in the indoor unit and in the remote controller.
One or the other of the temperature sensors is used for operation. Normally, the indoor unit sensor is set; however,
the procedure below can be used to switch to the remote controller sensor.
(1) Press and hold the + + buttons for 4 seconds or longer.
● The unit No. that is initially displayed is the indoor unit address of the group control master unit.
● Do not press the button.
(2) Use the temperature setting / buttons to select item code 32.
(3) Use the timer time / buttons to change the setting data from 0000 to 0001.
(4) Press the button. (The change is completed when the display stops blinking.)
(5) Press the button.
The unit returns to normal stop status. At this time, “Remote controller sensor” is displayed on the LCD.
● If 2 remote controllers are used for control, this setting can be made from either the main or sub remote con-
troller. However, the temperature sensor that is used is the sensor in the main remote controller.
● When group control is used, the remote controller sensor will not function unless the group address is set to the
address of the master indoor unit.
●
If both the remote sensor and remote controller are used, do not use the temperature sensor in the remote con-
troller.
