1.2.3 Data communication / bus
The controller is equipped with the VBus
®
for data trans-
fer with and energy supply to external modules. The
connection is carried out at the two terminals marked
“VBus
®
“ (either polarity). One or more VBus
®
modules
can be connected via this data bus:
• WMZ, calorimeter
• large display / Smart Display
• Datalogger
• COSMO heating circuit modules HKM
(up to 3 modules)

ground-common terminal block
The controller is equipped with 12 sensor inputs in
total. The ground connection for the sensors has to be
carried out via the ground terminal block (GND).
• Temperature sensors have to be connected to the
terminals S1 ... S10 and GND (either polarity)
• The irradiation sensor (CS10) is to be connected to
the terminals CS10 and GND with correct polarity.
Connect the terminal GND of the sensor to the termi-
nal GND of the controller (ground terminal block), and
the terminal CS of the sensor to the terminal CS10 of
the controller.
• A flowmeter V40 can be connected to the terminals
V40 and GND (either polarity).
