2. REGULATOR FUNCTION INSTRUCTIONS OF SPEED
ENG
If you turn the speed controller fully counterclockwise, the efficiency of the system will drop to only
30% of the original efficiency. If you turn the speed regulator fully clockwise, the system efficiency will
be 100%.
This function is intended to allocate part of the power of the solar panels for other uses or to be able
to start the pump when the solar installation is not capable of providing the necessary power to start
the pump at 100%.
3. REGULATOR FUNCTION INSTRUCTIONS ON DELAY
Turn the delay slider up to a whole number (according to the notches on the knob). If the system
detects that the water level in the well is below the level probe, the system will stop working and the
"WELL" indicator will light up.
When the water level exceeds the level probe again, the "WELL" indicator will start flashing for the
programmed delay time, after which the system will start up again.
The system will adjust the delay time according to what is indicated in the delay regulator. A period
between 0 and 30 minutes is available.
