Electrical Control Function

hours, after which, the unit exits this mode and
switches off.
1.3.7.4 The timer setting is available in this mode.
1.3.8 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 setting
automatically within 3 minutes after power returns.

Use the water-level switch to control drain pump.
The system checks the water level every 5
seconds.

----When the A/C operates in cooling (including
auto cooling) or forced cooling mode, the pump
begins running immediately and continuously until
cooling stops.
----If the water level increases up to the control
point, the LED displays an alarm code and the drain
pump opens and continually monitors the water
level. If the water level falls and LED alarm code is
no longer displayed (drain pump close delay is 1
minute), the unit goes back into its last mode.
Otherwise, the entire system (including the pump)
stops and the LED displays an alarm again after 3
minutes.
