Restoring operation
If the system shuts down, a code will
appear on the system interface display
signalling the type of shutdown and the
reason behind it.
To restore normal operation, follow the
instructions provided on the display or, if
the error persists, contact an authorised
Technical Service Centre for assistance.
(*) BUS power supply overload
A BUS power supply overload error may
occur due to the connection of three or
more devices within the installed sys-
tem. Devices which may overload the
BUS network include:
- Multizone module
- Solar pump assembly
- Module for instant production of do-
mestic hot water
To avoid overloading the BUS power
supply, set microswitch 1 on one of the
P.C.B.s inside the equipment connected
to the system (except the boiler) to OFF,
as illustrated in the fi gure.
