5-5. Room Temperature Sensor Settings
The indoor unit and the wireless remote controller are equipped with
room temperature sensors. The sensing of room temperature works
via one of them.
When the unit is shipped, it is set to the indoor unit. To switch it to the
remote controller, press the sensor button (the gure on the right)
inside the remote controller’s cover and then check that Main Sensor
on the LCD screen goes o.
<Note> Be sure to install the remote controller so as to face the
receiver.
If the unit does not receive any room temperature data from
the remote controller for ten minutes even with its sensing
function activated, the indoor unit sensor will automatically
start sensing the room temperature.
