Manual adjustment to minimum flow (LO-Teach)
The unit detects the current flow and sets this value as the minimum
display value for the LED display. In normal operation the first green
LED (LED 0) flashes when the flow falls below this value (or when it
comes to a standstill).
NOTE:
The LO-Teach operation may only be carried out after the HI-
Teach operation.
