Pump controller
The pump is configured in the factory for a maximum head of
7 metres.
When necessary, the user interface provides access to:

mance is displayed during functioning as a % of current
draw with respect to rated load. Alarm conditions can
be seen from the colour of LED.
- Setting Mode: Press button (1) to enter setting mode
and select the type of pump curve.
USER INTERFACE
The user interface consists of a push-button (1), a red/green
LED (2) and four yellow LEDs (3).

Alarm display
If the pump detects one or more alarm conditions, LED 1
changes from green to red. When an alarm is active, the LEDs
indicate the type of alarm as shown in the following table. If
more than one alarm is active at the same time, the LEDs only
show the alarm condition with the highest priority. Alarm priori-
ty follows the order of the table.
When no alarm is active, the user interface automatically dis-
plays pump performance.
