Relay output
Relays 1 and 4 are electromechanical relays for loads with high current consump-
tion. If loads with high current consumption are to be connected to relay 2 and /
or 3, pay attention to the following note:
Note:
The following pumps have to be controlled over the power relay:
• Pumps with a nominal current > 1A (see indication on the type label of
the pump)
• Pumps listed in the following:
e. g. Grundfos Magna 3, Wilo Stratos 50/1-12, Wilo Stratos 40/1-8,
KSB Calio 30-120

Data communication / Bus
The controller is equipped with the S-Bus for data transfer with external mod-
ules. The connection is carried out at the two terminals marked S-Bus and GND
(either polarity). One or more S-Bus modules can be connected via this data bus,
such as:
• CS-BS1 Communication module
• CS-BS6 Datalogger
• EM Extension module
2.4
SD card slot
The controller is equipped with an SD card slot.
With an SD card, the following functions can be carried out:
• Store measurement and balance values onto the SD card. After the transfer to a
computer, the values can be opened and visualised, e. g. in a spreadsheet.
• Prepare adjustments and parameterisations on a computer and transfer them
via the SD card.
• Store adjustments and parameterisations on the SD card and, if necessary, re-
trieve them from there.
• Download firmware updates from the Internet and install them on the con-
troller.
For more information about using an SD card, see page 44.
