Assemble cable screw connectors.
• Feed cable screw connector into the respective hole in the bot-
tom of the boiler and fasten with lock nut (next to the already
assembled screw connections).
• So that the zone controllers or EUROCONTROL can communicate
with the boilers, a 2-pole cable (by the customer) has to be in-
stalled from the bus module CIB to the controllers.
The bus module has a light-emitting diode (LED) to check the com-
munication between the boiler and bus module CIB-EUROCONT-
ROL. This LED indicates the condition of the LPB-bus signal and
signals possible faulty operation (tab. 1).
