1.22.5 Faulty cascade
In case of “failure” of one of the two SLAVE generators, which causes a lack of communication among the various boilers, it is nec-
essary to exclude the generator from the cascade and restore the sequence by connecting the generator before the faulty one to the
generator subsequent to the faulty one.
If MASTER generator needs to be excluded, disconnect the connection with the second generator (which is the first SLAVE), which
will become the new MASTER.
All connections for cascade management (cascade thermostat and probe, water heater thermostat/probe etc.) must be moved onto it.
Once the electrical connections have been changed, proceed with the cascade system auto-configuration (see
Self-configuration
).
