z *Only available with Wireless 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. HEAT” operation will not start. Operation starts and maintains the room
temperature at 50°F (10°C) when the temperature drops below 50°F (10°C).
When “•MIN. HEAT” operation stops, the room set temperature quickly returns to the preset temperature.
Outdoor unit low noise
z *Only available with Wireless 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.
