"Assist" menu
The "Assist" menu guides the user through the setting
of the pump. In each submenu, the user is presented
with a guide that assists throughout the setting.
This menu offers the following:
• Step-by-step instructions in how to set up the pump.
• A short description of the six control modes and
recommended applications.
• Assistance in fault correction.
Submenus:
• Assisted pump setup
• Setting of date and time
• Multi-pump setup
• Setup, analog input
• Description of control mode
• Assisted fault advice.

Operating status
"Operating status" shows the current operating mode
and the selected control mode, if any.
Pump performance
"Pump performance" offers the following:
• Q/H graph showing current duty point, flow, head,
power and liquid temperature.
• "Resulting setpoint" shows the setpoint set on the
pump, the external influence and the resulting
setpoint.
• Liquid temperature.
• Speed.
• Operating hours.
Warning and alarm
"Warning and alarm" offers the following:
• Actual warning or alarm, if any.
• Information about when the warning/alarm occurred
and disappeared and about corrective actions.
• Warning and alarm logs.
Heat energy meter
"Heat energy meter" is a monitoring function which
makes it possible to track the heat energy distribution
and consumption within a system. This prevents
excessive energy costs caused by system imbalances.
• The heat energy meter has an accuracy between
± 1 and 10 %, i.e. ideal for optimization purposes.
• Temperature input from the return pipe. The
temperature sensor is not supplied with the pump.

Note: MAGNA3 incorporates a calculator for flow and
flow-pipe temperature.
For further details, see section Curve conditions, page
32.
Work log history
"Work log history" offers the following:
• Every duty point and the operating conditions are
tracked and stored in the pump.
• The 3D work log and duty curve (over time) provide
instant overviews of historical pump performance
and operating conditions.
• The perfect tool for pump optimization, replacement
and fault finding.

Input for external sensor
An external differential-pressure sensor can be used to
control the flow in the system to obtain the externally
set pressure, which results in following benefits:
• Minimizes operating costs.
• Prevents valve noise.
• Ensures comfort (enough pressure).
