External probe (optional)
Connect the probe to the respective terminals. The maximum permissible length of the
electric cable connecting the boiler - external probe is 50 m. A common 2-wire cable can
be used. The external probe should preferably be installed on the North, North-West wall
or on the wall facing most of the main living-room. The probe must never be exposed to
the early morning sun, and in general (as far as possible) it should not be exposed to
direct sunlight; protect it if necessary. In any case, the probe must not be installed near
windows, doors, vents, flues or heat sources that could affect the reading.

Accessing the electrical terminal block
The electrical terminal block can be accessed after removing the front panel. Make the
electrical connections as shown in the wiring diagram in fig. 46 .

The output relay of the heating circulating pump (32) has a capacity of
8A@230Vac.
The output relays of the diverter valve (95) have a capacity of 5A@230Vac.
In case of loads with higher absorption, supporting relays with respective addi-
tional protection must be installed.
For the connection in cascade
Note: The boiler's electronics can manage up to 6 modules.
1. Connect the modules as shown in fig. 28 (example with 4 modules)

2. Carry out all the electrical connections (terminals 4 to 27) on module no. 1
3. On the remaining modules, only connect the power supply and possible contacts
for: burner lit (300), fault contact (301) and remote reset input (302).
4. Switch on the power to the entire cascade
5. After the "FH" procedure, check correct operation of the cascade:
• Module 1: arrow symbol at top left of the display
• Module 2: arrow symbol at bottom right of the display
• Module 3: arrow symbol at bottom right of the display
• Module 4: arrow symbol at top right of the display
If this does not occur, disconnect the power and check the wiring in fig. 28.
Settings
All adjustments must be made on all the modules.
Possible faults
If the electrical connection of a module is disconnected for any reason, module 1 will ac-
tivate fault F70.
If the electrical connection of a module is disconnected for any reason, the next module
will activate fault F71.
