10°C HEAT Operation

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.
