7.2.6 Setpoint in open-loop control
Hydro MPC and Multi-E
The setpoint is written to module 2 bytes 4 and 5 Setpoint as a
percentage value scaled in 0.01 % of the maximum performance.
The selected setpoint is reflected in module 41 UserSetpoint with
the same scaling.
The actual setpoint, whether it has been set via Grundfos GO
Remote, the pump or controller display or buttons, or the fieldbus,
can be read from module 20 ActualSetpoint, and it reflects
whatever limitations, for example power or frequency limits, that
might be active in the system. It equals the value that the booster
system actually uses.

The setpoint is written to module 2 bytes 4 and 5 Setpoint as a

UserSetpoint with the same scaling. From the fieldbus, it will get

7.2.7 Multi-E model H and twin-head pump TPED model H
control
• For Multi-E with a CIM module in the master pump only, set
CopyToLocal (Module 2, byte 1, bit 4) to value "1" in the
master pump.
• For Multi-E with a CIM module in two pumps, always set
CopyToLocal (Module 2, byte 1, bit 4) to value '1' in both
pumps. Any writings to the control module (module 2) must be
written to each pump.
• A TPED model H is essentially a Multi-E model H with two
pumps. Mount a CIM module in each pump head. Always set
CopyToLocal (Module 2, byte 1, bit 4) to value '1' in both pump
heads. Any writings to the control module (Module 2) must be
written to each pump head.

7.3 Status module (StatusModule, module 1)

The status module is a PROFIBUS/PROFINET input module
used for reading status from booster systems. Its data type is 10,
non-standard.
