Restoring operation
If the system shuts down, a code will appear
on the system interface display signalling the
120
type of shutdown and the reason behind it.
To restore normal operation, follow the in-
structions provided on the display or, if the
error persists, contact an authorised Techni-
cal Service Centre for assistance.
(*) BUS power supply overload
A BUS power supply overload error may oc-
cur due to the connection of three or more
devices within the installed system. Devices
which may overload the BUS network in-
clude:
- Multizone module
- Solar pump assembly
- Module for instant production of domes-
tic hot water
To avoid overloading the BUS power supply,
set microswitch 1 on one of the P.C.B.s in-
side the equipment connected to the system
(except the boiler) to OFF, as illustrated in
the fi gure.
