PWM 1 signal input (%)
93 ... 100
PWM 2 mode (profile solar)
In PWM 2 mode, the pump speed is controlled depending on the PWM input signal.
Behaviour when a cable breaks:
If the signal cable is disconnected from the pump, e.g. due to a cable break, the pump
stops.

PWM signal output (iPWM)
In iPWM mode, the pump produces a PWM output signal. In normal operation, either
the volume flow or the power is calculated. In case of a failure, a specific code is
transmitted.
