6.2.1 Settings in connection with pump
replacement
If an uncontrolled pump is to be replaced with a
UPE Series 2000, settings can be made according to
the tables below.

Read the tables as follows:
• If the maximum head of the existing pump is 5 me-
tres and the pump is running at maximum speed
under normal operating conditions, it is recom-
mended to set the UPE pump to 2.5 metres and to
select proportional pressure.
• If, however, the existing pump is running at a re-
duced speed, it is recommended to set the pump
to 2 metres and to select constant pressure.

6.3 Max. or min. curve duty

Can be set by means of the control panel or the
R100.
The pump can be set to operate according to the
max. or min. curve, like an uncontrolled pump, see
fig. 11.

The max. curve mode can be selected if an uncon-
trolled pump is required. In this operating mode, the
pump will operate independently of an external con-
troller, if installed.

The min. curve mode can be used in periods in
which a minimum flow is required. This operating
mode is suitable for night-time duty.

6.4 Constant curve duty

Can be set by means of the R100.
The pump can be set to operate according to a con-
stant curve, like an uncontrolled pump. Select one of
19 curves between the max. and min. curves, see
fig. 12.

6.5 Temperature influence

Can be set by means of the R100.
When this function is activated in proportional or
constant control mode, the setpoint for head will be
reduced according to the liquid temperature. It is
possible to set temperature influence to function at
liquid temperatures below 80°C or below 50°C.
These temperature limits are called T
The setpoint is reduced in relation to the head set
(= 100%) according to the characteristics below.
