Pump controllers
S pumps, range 58, can be controlled by Grundfos
Dedicated Controls (DC).
The Grundfos Dedicated Controls system can control
from one to six pumps.
The Dedicated Controls system starts/stops the S
pumps by means of:
• float switches,
• pressure sensor or
• ultrasonic sensor.
Furthermore, it is possible to control the water level by
both float switches and an analog pressure sensor or
ultrasonic sensor.
Optionally, it can control a mixer and/or a flush valve.
The Dedicated Controls system can be extended with
an IO 111 module per pump (for S pumps with built-in
analog sensor).
For further settings, see the installation and operating
instructions for the pump controller selected.
