Pump limitation
Pump speed limitation [9‑0D] defines the maximum pump speed. In normal
conditions, the default setting should NOT be modified. The pump speed limitation
will be overruled when the flow rate is in the range of the minimum flow (error
7H).
In most cases, instead of using [9-0D], you can prevent flow noises by performing
hydraulic balancing.
