FOR WALL-MOUNTED SECONDARY BOILERS
- Connect a 2-pole cable to the boiler's
electrical panel terminal board, taking care
to pass it from the back of the boiler and
inside one of the cable clamps on the
terminal board support plate.
- Form the electrical connections as shown
here.
- Tighten the cable clamp.
- When the switch for the BV control panel is
in the 0 position, the boiler is switched off,
even if called for by the secondary boiler.
- For wall-mounted secondary boilers it is not
possible to use the Summer/Winter selector
as this function is already included in how
the secondary boiler operates.
FOR NOVELLA SECONDARY BOILERS
- Connect a 5-pole cable to the boiler's
electrical panel terminal board, taking care
to pass it from the back of the boiler and
inside one of the cable clamps on the
terminal board support plate.

here.
- Tighten the cable clamp.
FOR AVTONOM SECONDARY BOILERS
- Connect a 3-pole cable to the boiler's
electrical panel terminal board, taking care
to pass it from the back of the boiler and
inside one of the two cable clamps on the
