Series 4 Models: “Wall” Type Top Class R32 Refrigerant AC
5.10 Auto-Restart function
• The indoor unit has an auto-restart module that allows
the unit to restart automatically. The module automatically
stores the current settings (not including the swing setting)
and, in the case of a sudden power failure, will restore
those settings automatically within 3 minutes after power
returns.
• If the unit was in forced cooling mode, it will run in this
mode for 30 minutes and turns to auto mode with
tempera-
ture set to 24°C.
• If there is a power failure while the unit is running, the
compressor starts 3 minutes after the unit restarts. If the
unit was already off before the power failure, the
compres-
sor starts 1 minute after the unit restarts.
5.11 Refrigerant Leakage Detection
• With this new technology, the display area will show
“EC” when the outdoor unit detects refrigerant leakage.
• When compressor is active, the value of the Coil tempe
-
rature of evaporator T2 has no change or very little
change.
5.12 Louver Position Memory Function
When starting the unit again after shutting down, its louver
will restore to the angle originally set by the user, but the
precondition is that the angle must be within the allowable
range; if it exceeds, it will memorize the maximum angle
of the louver. During operation, if the power fails or the
end user shuts down the unit in the turbo mode, the louver
will restore to the default angle.
5.13 8°C Heating (Optional)
In heating mode, the temperature can be set to as low as
8°C, preventing the indoor area from freezing if
unoccu-
pied during severe cold weather.
5.14 Self Clean (Optional)
• If you press “Self Clean” when the unit is in cooling or
drying mode:
• For cooling only models, the indoor unit will run in low
fan mode for a certain time, then ceases operation.
• For these heat pump models, the indoor unit will run
in
fan-only mode, then low heat, and finally in fan-only
mode.
• Self Clean keeps the indoor unit dry and prevents mold
growth.
5.15 Follow Me (Optional)
• If you press “Follow Me” on the remote, the indoor unit
will beep. This indicates the “Follow Me” function is active.
• Once active, the remote control will send a signal every
3 minutes, with no beeps. The unit automatically sets the
temperature according to the measurements from the
remote control
.
• The unit will only change modes if the information from
the remote control makes it necessary, not from the unit’s
temperature setting.
• If the unit does not receive a signal for 7 minutes or you
press “Follow Me”, the function turns off. The unit
regula-
tes temperature based on its own sensor and settings.
5.16 Silence (Optional)
Press “Silence” on the remote control to enable the
SILENCE function. While this function is active, the com-
pressor frequency is maintained at a lower level than F2.
The indoor unit will run at faint breeze, which reduces
noise to the lowest possible level.
5.17 Information Inquiry
• To enter information inquiry status, complete the fol-
lowing procedure within 10 seconds:
• Press LED 3 times.
• Press SWING 3 times.
• If the proceeding is successful, you will hear beeps for
2 seconds.
• Use the LED and SWING buttons to cycle through
information displayed.
• Pressing LED will display the next code in the sequence.
Pressing SWING will show the previous.
• The following table (see next page) shows information
codes. The screen will display this code for 2 seconds,
then the relevant information for 25 seconds.
