(*) BUS power supply overload
A BUS power supply overload error may occur due to the con-
nection of three or more devices within the installed system.
Devices which may overload the BUS network include:
- Multizone module
- Solar pump assembly
- Module for instant production of domestic 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 Tank) to OFF, as illustrated in the  gure.
