[3] FUNCTION
1. Restart control
Once the compressor stops operating, it will not restart for 180 sec-
onds to protect the compressor.
Therefore, if the operating compressor is shut down from the remote
control and then turned back on immediately after, the compressor will
restart after a preset delay time.
(The indoor unit will restart operation immediately after the ON switch
is operated on the remote control.)
2. Startup control
When the air conditioner starts in the cooling mode, if the room tem-
perature is 2℃ higher than the set temperature the air conditioner
operates with the operating frequency at maximum.Then, when the set
temperature is reached, the air conditioner operates at the operating
frequency determined by fuzzy logic calculation, then enters the nor-
mal control mode after a while.
3. ON timer
The ON timer can be activated by pressing the ON timer button. When
the ON timer is activated, the operation start time is adjusted based on
fuzzy logic calculations 1 hour before the set time so that the room
temperature reaches the set temperature at the set time.

4. OFF Timer (Sleep Operation)
The OFF timer can be activated by pressing the OFF timer button.
When the OFF timer is set, the operation stops after the set time.
When this timer is set, the compressor operating frequency lowers for
quieter operation, and the room temperature is gradually varied after
one hour (reduced 1°C three times (max. 3°C) in heating, or increased
0.3°C three times (max. 1°C) in cooling or dehumidifying operation) so
that the room temperature remains suitable for comfortable sleeping.
