Pump control
The circulation pump can be controlled by an external PWM signal
(profile for use in heating systems) or without a PWM signal by
selecting a pump performance curve.
A maximum curve of a pump working range can be defined.
- with PWM signal the pump speed changes with the signal value up to the maximum of the
selected curve
- without PWM signal the pump runs at the max. speed according to the selected curve
