✭ 100% of setpoint
Function:
In systems with constant pressure control, it is
advantageous to increase the pressure in the system
before the lead pump stops. This helps to avoid
frequent starting and stopping, e.g. in the case
of leaks in the water supply system.
Description of choice:
Set the required Boost setpoint as a percentage
of the resulting reference under normal operation.
100% corresponds to the reference without
boost (supplement).
