26. Winter cool
Cooling operation is available during the winter season by the built in
winter cool function.
Lower limit of outdoor temperature range is -10°C.
When the outside air temperature is low, the outdoor unit fan operates
at slower speed.
NOTE: Built-in protect device may work when outdoor temperature
falls below 21°C, depending on conditions.

27. Auto restart
When power failure occurs, after power is recovered, the unit will auto-
matically restart in the same setting which were active before the
power failure.
27.1. Operating mode (Cool, Heat, Dry)
• Temperature adjustment (within 2°C range) automatic operation
• Temperature setting
• Fan setting
• Air flow direction
• Power ON/OFF
• Automatic operation mode setting
• Swing louvre
• Plasmacluster mode
27.2. Setting not memorized
• Timer setting
• Full power operation setting

27.3. Disabling auto restart function
By removing (cutting) jumper  (JP ) on the printed circuit board
(PCB), the auto restart function can be disabled.

28. Energy Saving Operation

28.1. Cool/Dry Operation
By pressing ENERGY SAVE button during Cool/Dry operation, the set
temperature will vary with 1/f fluctuation. 1/f fluctuation resembles fluc-
tuation existing in nature, and is said that it gives relaxation.(1/f Fuzzy
Logic) By varying the set temperature in +1°C ~ -0.33°C range follow-
ing 1/f fluctuation, the rise in set temperature will correspond to +0.5°C
in calculation. Since this air conditioner model is inverter type, com-
pressor output will also vary in the same manner. As a result this will
help saving electricity cost.
28.2. Heat Operation
By pressing ENERGY SAVE button during Heat operation, set temper-
ature will vary in -2°C ~ +1°C range, and will correspond to lowering
the set temperature -1°C in calculation.
NOTE: When used in combination with Full Power control, priority is
given to the latter pushed button's control.
