2. Auto-setback by sensor (with presence sensor)
After pre-determined time has elapsed without detection of human presence, the unit automatically
shifts the target temperature gradually for energy saving.
The target temperature displayed on the remote controller remains same as the initial set value
during the above change of target temperature.
The target temperature shifts within the range of the highest programmable temperature while in
cooling operation and the lowest programmable temperature while in heating operation.
Upon human detection, the target temperature returns to the original setting.
