2.2 GRUNDFOS Control 2000 F
The GRUNDFOS Control 2000 F controls a number of pumps,
some are operated via a frequency converter and some are
mains-operated.
The Control 2000 F always includes the PFU 2000 with applica-
tion-optimized software, but it is also available with a PMU 2000.
The operating conditions and factory settings can be optimized
via a temporarily connected PMU 2000.
If the Control 2000 F includes the PFU 2000 only, it will be placed
in the front cover. If the Control 2000 F includes both the
PFU 2000 and the PMU 2000, the PMU 2000 will be placed in the
front cover and the PFU 2000 inside the cabinet.
The Control 2000 F is factory-assembled and tested with the con-
trol parameters mentioned in the “List of Control Parameters”,
which is delivered with the booster set.
The Control 2000 F offers the following functions:
• Closed-loop control.
• On/off operation at low flow.
• Automatic pump changeover to mains operation in case of
damage to the frequency converter.
• Automatic cascade control of pumps.
• Selection of switching sequences, automatic pump change
and pump priority.
• Manual operation.
• Possibility of various analog setpoint influences:
– friction loss compensation (flow-dependent setpoint
control with or without flow measurement),
– temperature-dependent setpoint control,
– setpoint adjustment.
• Possibility of various digital remote-control functions:
– system on/off,
– reduced operation,
– setpoint control with two-point switch,
– setpoint control with three-point switch,
– alternative setpoint,
– fire-fighting operation,
– switching off individual pumps.
• Pump and system monitoring functions:
– minimum and maximum limits of actual value,
– pre-pressure,
– motor protection,
– BUS communication.
• Display and indication functions:
– 2 x 24 character LCD display,
– green indicator light for operating indications and
red indicator light for fault indications,
– potential-free changeover contacts for operation and fault.
• Clock functions.
• GRUNDFOS BUS communication.
