Control modes
•AUTO
ADAPT
(factory setting) which is suitable for
most installations.
•FLOW
ADAPT
in systems where flow limitation is
required.
• Proportional-pressure control in systems with
considerable pressure losses in relation to large
flow variations.
• Constant-pressure control in systems with
insignificant pressure losses in relation to large flow
variations.
• Constant-temperature control in heating systems
with a fixed system characteristic, for example
domestic hot-water systems.
• Differential-temperature control in heating and
cooling systems.
• Constant-curve duty.
For further information on control and operating
modes, see Functions, page 14.
Automatic determination of the setpoint
If you know the duty point, you can enter the value on
the display when setting the pump. The pump then
automatically calculates the corresponding setpoint.
See fig. 8.

control mode and entered Q and H values
Communication
The Grundfos CIM modules (Communication Interface
Module) enable the MAGNA3 to connect to standard
fieldbus networks, offering substantial benefits:
• complete process control and monitoring
• modular design, prepared for future requirements
• based on standard functional profiles
• simple configuration and easy installation
• open communication standards
• reading warning and alarm indications.
For further details, see CIM modules, page 27.

(BMS)
Note: A gateway is a device that facilitates the transfer
of data between two different networks based on
different communication protocols.
