6. Functions
Some functions can only be selected by means of
the remote control R100. Where and how the differ-
ent settings are made will appear from section
7. Setting the pump.
6.1 Control modes
UPE Series 2000 pumps can be set to the control
mode which is most suitable for the individual sys-
tem.
Two control modes are available:
• Proportional pressure (factory setting).
• Constant pressure.
Proportional pressure control:
Can be set by means of the control panel or the
R100.
The pump head is reduced at falling water demand
and increased at rising water demand, see fig. 10.
Constant pressure control:
Can be set by means of the control panel or the
R100.
The pump maintains a constant pressure, irrespec-
tive of water demand, see fig. 10.
