Since the front panel is easy to remove, maintenance is also easy.
10°C HEAT Operation
z
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 will not start. Operation starts and maintains the room •
temperature at 10 °C when the temperature drops below 10 °C.
