This control is effective only for one indoor unit or group control.

- 2 deg. at heating. For example, if cooling is selected, the set temperature changes from
20° C to 22° C.
(The display of the remote controller remains 20° C.)
the room temperature during the operation is as follows.
Heating to Cooling; Room temp. ≥ Shifted temp + 0.5 deg.
Cooling to Heating; Room temp. ≤ Shifted temp -1.0deg.
For example, if the room temperature rises above 22.5 °C (=22+0.5) during the cooling
operation at the room temperature 20° C set by the remote controller, the operation
changes to cooling. When the room temperature lowers below 17° C (=18-1.0) thereafter,
the operation changes to heating again.
room air temp. is sensed as 4 deg. lower than suctioned air at indoor unit taking into
account of the temperature gap between upper part and lower part of the room.
Accordingly, in this example, when the body sensor detection temperature reaches more
than 26.5 °C, the operation is changed from heating to cooling.
