1. General description
The UPE Series 2000 is a complete range of circula-
tor pumps with integrated differential pressure con-
trol enabling adjustment of pump performance to the
actual system requirements. In many systems, this
will mean a considerable reduction in power con-
sumption, prevent noise from thermostatic valves
and similar fittings, and improve the control of the
system.
The desired head can be set on the pump control
panel.
These instructions apply to the pump types
UPED 50-120, UPED 65-120, UPED 80-120 and
UPED 100-60.
The pump offers the following functions:
• Control of twin-head pump:
- Alternating operation,
- Standby operation,
- Synchronous operation,
- Single-pump operation.
• Proportional-pressure control (factory setting).
The head is changed in accordance with the flow
demand. The desired head can be set on the
pump control panel.
• Constant-pressure control. A constant head is
maintained, irrespective of flow demand. The
desired head can be set on the pump control
panel.
• Constant curve duty. The pump runs at a con-
stant speed on or between the max. and min.
curves.
• Temperature influence. The head varies depend-
ing on the liquid temperature.
• External fault signal via a potential-free output.
• External analog control of head or speed from
an external 0-10 V signal transmitter.
• External forced control via inputs for:
- Start/stop,
- Max. curve,
- Min. curve (night-time duty).
• Bus communication. As the UPE Series 2000
incorporates an input for bus communication, the
pump can be controlled and monitored by a
GRUNDFOS Pump Management System 2000 or
a building management system.
• Remote control. The pump can be operated by
means of the Grundfos wireless remote control
R100.
