3. Auto-off by sensor (with presence sensor)
After pre-determined time has elapsed without detection of human presence, the unit automatically
stops operation.
The auto-off time can be set between 1- 24 hours by the hour.
Once the unit stops operation by auto-off function, the system would not restart even if the human
is detected again.
 Auto-off by sensor is enabled only when decoration panel BYFQ60C2W1W(S), sensor kit
BRYQ60A2W(S) and wired remote controller BRC1E73 are connected to the main unit and
auto-off by sensor is set to “enabled” on the wired remote controller.

4. Room temperature adjustment by sensing (with floor sensor)
The system uses living space temperature calculated from temperatures detected by room
temperature thermistor (suction air thermistor in the indoor unit) and floor sensor, as the target
temperature.
Operation becomes more optimized by using not only suction air temperature but floor temperature.
 This function is enabled when decoration panel BYFQ60C2WAW(S) and sensor kit
BRYQ60A2W(S) is connected to the main unit.
