z

*Only ava ilable with W ireless RC.

The room temperature can be set to go no lower than 50°F (10°C),
thus ensuring that the room does not get too cold when not occupied

Caution)

When the room temperature is higher than 50°F (10°C), “ • MIN. HE AT” operation will not start. Operation star ts and maintains the room
temperature at 50°F (10°C) when the temperature drops below 50°F (10°C).

When “ • MIN. HE AT” operation stops, the room set temperature quickly returns to the preset temperature.

*Only ava ilable with W ireless RC.

When air-conditioner operates in large capacity, operation noise of outdoor unit will be suppressed. In case
of room temperature being close to setting temperature, operation noise might not decrease.
