6.1.1 Boiler pump with speed regulation to a temperature rise
set-point value (e.g. boiler cascade)
Prog. no.

The parameter "Pump speed min" (prog. no. 2322) must be set to the
following values:
30% for Wilo Stratos pumps
10% for Grundfos Magna pumps
The pump function is not guaranteed if values smaller than those specified
are set.
See
The pump manual and in particular the information on the
characteristic pump curve and minimum possible actuation must
be observed.
6.1.2 Boiler pump with speed regulation to the boiler set-point
value for storage tank charging (e.g. buffer vessel or
combi cylinder)
Prog. no.
2320
2322
2323
5891
6085
Important
The parameter "Pump speed min" must be adjusted to the
characteristic pump curve, i.e. prog. no. 2322 must be set such
that the pump is not operated below its minimum characteristic
curve.
See
The pump manual and in particular the information on the
characteristic pump curve and minimum possible actuation must
be observed.
