Can be used as setpoint input or pressure
sensor input (suction pressure)
The analog input AI 1 is used mainly as pressure value input. The analog input AI 2 is used
mainly as the setpoint input, but with control modes n-c, PID and p-c it can be used as
sensor input for pressure sensor at suction port to support optional function “Lack of water
detection via pressure sensor”. In this case, the pressure sensor must be configured as AI 2
accordingly.
