Air ow mode can be set in 4 steps and more detailed air ow setting is possible.
Powerful operation
z
Continuous operation by maximum air ow and maximum compressor speed after a certain
period of time allows the temperature to reach the setting temp. quickly.
MIN. HEAT Operation
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 does 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.
