Disconnect the connecting cable to the boiler control unit (ST 26). Now
you can put the front cladding down to the side and you have convenient
access to all connection points on the I/O modules.
I/O module (masterboard)
You must be able to switch off the system via an escape switch. The “ stop switch must be installed outside of the
boiler room. (Connection, “stop switch – plug-type connector, section 17).
When connecting sensors and motors, strictly ensure that the
control system
is de energized, for the following reasons:
• Protection against electric shock
• Connections are not short-circuit proof
• Control system must be switched off to initialise.
All cabling diagrams and connection diagrams required for professional installation are provided in section 17.
Wiring that is more extensive than that shown in the diagrams, or that deviates from that shown in the diagrams is
beyond our sphere of responsibility and invalidates warranty claims.
