3. General description

27
Grundfos E-pumps have standard motors with integrated
27
frequency converter. The pumps are for single-phase or
28
three-phase mains connection.
28
The pumps have a built-in PI controller and can be set up for an
28
external sensor enabling control of the following parameters:
28
• pressure
29
• differential pressure
29
• temperature
29
• differential temperature
30
• flow.
31
From factory, the pumps have been set to control mode
32
uncontrolled. The PI controller can be activated by means of
32
R100.
32
The pumps are typically used as circulator pumps in large heating
32
or cooling water systems with variable demands.

3.1 Settings

32
The desired setpoint, can be set in three different ways:
32
• directly on the pump control panel
32
• via an input for external setpoint signal
32
• by means of the Grundfos wireless remote control R100.
32
All other settings are made by means of the R100.
33
Important parameters such as actual value of control parameter,
33
power consumption, etc. can be read via the R100.
