COOLING
mode.
Outdoor Fan
The outdoor fan operates the same as in the
COOLING
mode.
Forced OPERATION Function
When the air conditioner is off, press
TOUCH
to engage the

Operation Rules
Forced COOLING Mode
The compressor runs at the F2 frequency and the indoor fan runs in the
BREEZE
mode. After running for 30 minutes. the air conditioner
enters the
AUTO
mode at the 75.2
F(24
C) setting temperature.
Forced AUTO Mode:
The
Forced
AUTO
mode is the same as the normal
AUTO
mode with a
75.2
F(24
C) setting temperature.
Forced DEFROSTING Mode:
1. Press and hold
AUTO/COOL
for 5s to enter the mode. The indoor
fan stops and the defrosting lamp illuminates. Use the remote
controller to exit this mode and turn off the air conditioner to stop the
normal
DEFROSTING
mode.
2. To exit the
Forced
DEFROSTING
mode, press and hold
AUTO/
COOL
for 5s again.
AUTO-RESTART Function
The indoor unit is equipped with the
AUTO-RESTART
function,
which is carried out through an auto-restart module. In the event of a
sudden power failure, the module memorizes the setting conditions prior
to the power failure. The air conditioner resumes the previous operation
setting (not including the
SWING
function) automatically three (3)
minutes after the power returns.
If the memorization condition is the
Forced
COOLING
mode, the air
conditioner runs in the
COOLING
mode for 30 minutes and turns to the
AUTO
mode at the 75.2
F(24
C) setting temperature. If the air
conditioner is off before the power turns off and the air conditioner is
required to start up, the compressor delays start-up for 1 minute before
powering on. In other instances, the compressor waits three (3) minutes
before restarts.
Refrigerant Leakage Detection
With this new technology, the display area displays
“EC”
when the
outdoor unit detects a refrigerant leak. This function is only active in the
COOLING
mode. The function can further prevent the compressor
from being damaged by a refrigerant leak or a compressor overload.
•
Open Condition:
When the compressor is active, the value of the
coil temperature of evaporator T2 experiences no to very little
change.
Louver Position Memory Function
When starting the air conditioner again after a shut down, the louver
returns to the angle originally set by the user, however the precondition
is that the angle must be within the allowable range. If the louver
exceeds the allowable range, the air conditioner memorizes the
maximum angle of the louver. During operation, if the power fails or the
end user shuts down the air conditioner in the
TURBO
mode, the louver
returns to the default angle.
