10.2 SWITCHING THE PUMP ON AND OFF
• When the pump is first connected to the network, it will
operate with factory settings, i.e. in automatic mode
• At each following start-up, the pump will operate with
the last settings that were set prior to its last shut-down
• To switch the pump off, press and hold the - key for
5 seconds, until OFF is shown on the display. Once the
pump is switched off, the OFF sign will remain visible
on the numerical display
• To turn the pump on, briefly press the - key

10.4 SETTINGS
• To switch between modes (except for night mode),
hold the √ key for 3 seconds and select the desired
operating mode of the pump with + or - keys. Confirm
the selection with the √ key
• Once the operating mode is confirmed, the display shows
the settable parameter (not valid for automatic mode)
• If necessary, set the parameter value with + and -
keys and confirm the setting with the √ key
• Night mode can be activated/deactivated by simultaneously
pressing + and - keys and holding them for 3 seconds
• To scroll through the parameter values within a mode

11. OPERATING MODES DESCRIPTION
The pump can operate in 4 different operating modes.
Depending on the system in which the pump operates, the
pump can be set in the most appropriate mode.
Pump modes:
• Automatic mode (factory setting)
• Proportional pressure
• Constant pressure
• Constant speed
Each mode can coexist with the night mode
A
Automatic mode (factory setting)
In automatic mode, the pump automatically sets its operating
pressure according to the status of the hydraulic system.
By doing so, the pump automatically finds the optimal
operating position.
This mode is recommended in most systems. The parameters
cannot be set; they can only be scrolled through.
Proportional pressure (Fig. 5.3a)
In this mode the pump continually
regulates the head based on the flow
rate, by varying the pressure in linear
fashion within the maximum to minimum
range. The value to be set (Hset on the
drawing) corresponds to the maximum
pressure at maximum power; at 0 flow
the pressure will be equivalent to 50% of the pressure
set (Hset/2). Between these two values, the pressure will
change linearly, in relation to the flow.
In this mode only the pump pressure can be set (Hset
on the drawing); the remaining parameters can only be
scrolled through.
Constant pressure (Fig. 5.3b)
In this mode the pump maintains the
currently set pressure (Hset on the
drawing) constant, regardless from the
demand of the system (from 0 flow to
maximum power, at which point the
