Energy saving control

Human sensor catches movements of people in a room, and operates with lower capacity when the room
is empty. When people come back to the room, it automatically returns to the previous operating mode.
10°C HEAT operation
 *Only available with Wireless RC.
The room temperature can be set to go no lower than 10 °C,
thus ensuring that the room does not get too cold when not occupied
NOTE:
When the room temperature is higher than 10 °C, “•10°C HEAT” operation will not start. Operation starts and maintains the room
temperature at 10 °C when the temperature drops below 10 °C.
