7.3.1 Setting in connection with pump replacement

If an uncontrolled pump is to be replaced with a
UPE(D) FZ pump, settings can be made according to
the tables below.

Read the tables as follows:
• If the maximum head of the existing pump is
6 metres and the pump is running at maximum
speed under normal operating conditions, it is
recommended to set the pump to 3 metres and to
select proportional pressure.
• If, however, the existing pump is running at a
reduced speed, it is recommended to set the
pump to 2 metres and to select constant
pressure.

7.4 Max. or min. curve duty

To be set on the control panel, with the R100 or a
building management system via bus. It is not
possible to set max. curve duty via the external
input.
The pump can be set to operate according to the
max. or min. curve, like an uncontrolled pump.

The max. curve mode can be selected if an
uncontrolled pump is required. See section
8.2 Control panel. In this operating mode, the pump
will operate independently of an external controller,
if installed.
The min. curve mode can be used in periods in
which a minimum flow is required. This operating
mode is for instance suitable for night-time duty.

7.5 Constant-curve duty

To be set with the R100.
The pump can be set to operate according to a
constant curve, like an uncontrolled pump.
Select one of the curves between the max. and
min. curves. See fig. 11.
