HIGH POWER

This function acts to raise the power but keeps the AC system in the same operating mode.

This function is set with the HIGH POWER button on the remote controller.

(It can be set regardless of the temperature and fan speed settings.)

HIGH POWER operation from remote controller

The unit operates at maximum output for 30 minutes, regardless of the desired temperature.

The fan speed is 1 step above "High."

Frequency

MAX

NIGHT SETBACK

When NIGHT SETBACK operation is set, the temperature and fan speed settings will be adjusted automatically to allow comfortable sleep.

When NIGHT SETBACK operation is set, " mark" appears on the remote controller. The main unit display lamp also becomes dimmer.

COOL and DRY modes

When the night setback mode is selected, the air conditioner automatically raises the temperature setting 2°F(1°C) when 30 minutes have passed after the selection was made, and then another 2°F(1°C) after another 30 minutes have passed, regardless of the indoor temperature when night setback was selected. This enables you to save energy without sacrificing comfort. This function is convenient when gentle cooling is needed.
