Set the minimum opening angle between 0 and 100%.
NOTE
The minimum opening angle has been reached at the last
moment before the valve opens, i.e., immediately before the
start of the flow.
To exit the Set-up mode, press down both keys at the same
time.
The unit saves the set values, and changes to the Standard
mode, i.e., the Programming mode is also exited.
NOTE
You can remove the control unit from the compact flow control-
ler, e.g., after programming, without affecting the set process.
The programmed values remain stored in the flow controller.
ATTENTION!
Protection class IP65 is only guaranteed with the housing
closed.
For this reason, always replace the housing lid and
screw it down tightly.
