Speed Change
: By default, the pump speed level is set to 10. When the pump is
turned OFF, the speed level during the time of turning OFF is saved.

Pump Soft Start
: When the pump is turned ON, the pump speed is softly ramped up
to maximum speed in about 5 seconds, and then the pump speed goes back to
saved speed level/ default level. During the 5 second soft ramp up, the ‘Speed+’,
‘Speed-’ and ‘Pulse’ mode button for the corresponding pump are disabled.

down after 20 minutes of operation and save the speed level for next cycle use.

Purge mode
: The drying cycle will start automatically 15 minutes after the system
stops (The system can be either stopped manually, or it stops automatically after 20
min using the built in timer, or it stops automatically if no water is detected on water
level sensor). The air pump will run at maximum speed for duration of 2 minutes.

counts down from 120 sec to 0 sec and after that the air pump will automatically stop.
