Setting channels nMN or n1MN and n2MN, default a relative minimum speed for
connected pumps for outputs R1 and R2.
CAUTION:
When using consumers without variable speed control (e.g. valves), set the value
to 100% to disable the variable speed control.
After you have set the last parameter in the commissioning menu, the controller
will prompt you for confirmation.
Press key 3 to confirm your settings.
The controller is now ready to operate. The settings made in the commissioning
menu can be changed any time after the commissioning in the relevant parame-
ter.
