

Easy maintenance and always clean. Troublesome maintenance has been made easy.

Since the front panel is easy to remove, maintenance is also easy.

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.
