7.5.4 RS-485 interface
Use the S1 and S2 RS-485 interfaces to retrieve all controller data and to enable
the communication with control centres or other devices.
• S1 interface
– A maximum 10 devices can be used in a master-slave linked circuit
via the this interface.
• S2 interface
– "PIS" pressure and "LIS" level.
– Operating modes of the "PU" pumps.
– Operating states of the motorised ball valve/solenoid valve.
– Values of the "FQIRA +" contact water meter.
– All messages.
– All entries in the fault memory.
The following bus modules form part of the optional accessories available for
interface communication.
 Note!
If required, please contact the Reflex Customer Service for the protocol
of the RS-485 interface, details of the connections and information about
the accessories offered.
