• the analogue signal only changes the setpoint
• and the pump is additionally switched off through the analogue signal.
A setpoint change can be done through analogue signals without switching on and off the
pump through the signals. In this case, "Switched off" is selected.
If the "On/off by analogue signal" function is switched on, the limit values must be defined
for the switch on/off.
Subsequently assign the MIN signal/value and MAX signal/value.
For the transfer of analogue signal values to setpoints, only the transfer ramp is now defined.
For this purpose, the minimum and maximum support points of the characteristic curve are
