10°C HEAT Operation
z *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
Caution)
• When the room temperature is higher than 10°C, “10°C HEAT” operation does not start. Operation starts and maintains the room
temperature at 10°C when the temperature drops below 10°C.
• When “10°C HEAT” operation stops, the room set temperature quickly returns to the preset temperature.
