2. Room Temperature Sensor Settings
Common to All Models
• The indoor unit and the wireless remote control are equipped with
indoor temperature sensors. The sensing of indoor temperature
works via one of them.
• When the unit is shipped, it is set to the indoor unit, but to switch to
the remote control, press the Sensor button (diagram at right) inside
the remote control's cover and then check to make sure that Main
Sensor on the LCD screen goes off.
NOTE
Even when the Sensor switch has been set to the remote control,
if the unit does not receive any room temperature data from the remote
control for ten minutes, it automatically switches back to the indoor unit
sensor, so be sure to install the remote control facing the receiver.
