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

floating relay
The controller is equipped with 12 sensor inputs in
Bus
total. The ground connection for the sensors has to be
VBus
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).
