7.3.2 Pumps with pressure sensor
The pump can be set to one of two control modes, i.e. controlled
and uncontrolled, fig. 18.
In control mode controlled, the pump will adjust its performance,
i.e. pump discharge pressure, to the desired setpoint for the
control parameter.
In control mode uncontrolled, the pump will operate according to
the constant curve set.

or uncontrolled (constant curve)
8. Setting up the pump
8.1 Factory setting
Pumps without factory-fitted sensor
The pumps have been factory-set to control mode uncontrolled.
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 control mode controlled.
The setpoint value corresponds to 50 % of the sensor measuring
range (see sensor nameplate).
9. Setting by means of control panel
The pump control panel, see fig. 19 or 20, incorporates the
following buttons and indicator lights:
• Buttons, and , for setpoint setting.
• Light fields, yellow, for indication of setpoint.
• Indicator lights, green (operation) and red (fault).
