6. Setting the pump

6.1 Pumps without factory-fitted sensor

The pumps have been factory-set to uncontrolled
operation.
In uncontrolled-operation mode, the pump will operate
according to the constant curve set, fig. 13.

6.2 Pumps with pressure sensor

The pump can be set to two control modes, i.e. controlled
and uncontrolled operation, fig. 14.
In controlled-operation mode, the pump will adjust
its performance to the desired setpoint for the control
parameter (pump discharge pressure).

and in uncontrolled-operation mode
In addition to normal operation (controlled or uncon-
trolled operation), the following operating modes can
be selected, Stop, Min. or Max., fig. 15.

MAX = 100%
MIN = ~20%
Q

Min. and max. curves
The max. curve can for instance be used in connection
with the venting procedure during installation.
The min. curve can be used in periods in which a
minimum flow is required.
The operating modes (Stop, Normal, Min., Max.) can all
be set on the pump control panel.
If the electricity supply to the pump is disconnected,
the pump setting will be stored.

Caution

6.3 Factory setting

Pumps without factory-fitted sensor:
The pumps have been factory-set to uncontrolled ope-
ration. The setpoint value corresponds to 100% of the
maximum pump performance (see data sheet for the
pump).
Pumps with pressure sensor:
The pumps have been factory-set to controlled ope-
ration. The setpoint value corresponds to 100% of the
sensor measuring range.
Q
Pump internal voltage!
Use only electrically isolated contact.
The pump only recognises the control
or digital input status.
