2.3 BUS connection
All of the bus models are connected with a bus line. The specification of the cable that is used must adhere to
the LIYCY 2x2x0.5 type. A maximum cable length of 200 m must be observed. The cable length can be
extended using the Fröling bus repeater.
The bus modules must be connected in series; although no specific sequence of the module types and
addresses is specified. A star/stub cable is not permitted.
As the control units are supplied with voltage in addition to transferring data, problems caused by voltage drops
can occur depending on the number of modules and existing cable lengths.
A voltage supply unit must be used for every touch room console (heating circuit module, hydraulic module).
