About Amenity facilities
Amenity facilities enable to start the operation a little earlier, so that the room
should approach optimum temperature at ON time when the operation is
started by ON-TIMER.
• Mechanism
The room temperature is checked
60 minutes before the timer is at
ON. Depending on the tempera-
ture at that time, the operation
starts 5 to 60 minutes before the
timer is at ON.
• The Amenity facility only func-
tions for COOL and HEAT op-
eration mode (including AUTO).
It does not work for DRY mode.

About SLEEP operation
When SLEEP operation is selected, the room temperature is automatically
controlled after a while, ensuring that the room is not too cold during cooling
or too warm during heating.
• During cooling : the preset temperature is lowered by 1°C at the start of
SLEEP operation (when the timer is set). After that, the temperature goes
up by 1°C every an hour to become 2°C higher.
• During heating: Preset temperature is lowered by 1°C at the start of SLEEP
operation (when the timer is set). After that the temperature is lowered by
1°C every 30 minutes to become 3°C lower in an hour and 6°C lower in two
hours.
