A: JUMPER

When needed, the P.C.B. allows the different options to be selected by means of a wire link.

The boiler has the following basic arrangement:

1OPEN

2CLOSED (jumper)

3OPEN

4OPEN

5OPEN

6OPEN

7CLOSED

8OPEN (MFFI); CLOSED (SYSTEM)

NOTE: under absolutely no circumstances must jumpers 2, 7 and 8 be removed. The opening of such contacts will lead to boiler malfunction.

This is the factory configuration. It is recommended that this set-up not be changed, unless under the following particular circumstances:

JUMPER 3: if the contact is closed, the Secondary Output (flying clamp connected to connection C7; positions 1-9) controls a LPG valve (optional).

JUMPER 4: if the contact is closed, the continuous operation of the pump is selected. If the contact remains open, it has no effect and there is no change in the operation of the boiler.

JUMPER 5: if the contact is closed, the signal transmitted by the connection of the secondary output clasp (connected to C7; positions 1-9) relates to a secondary pump (optional). If the contact remains open, the output signal controls a zone valve (optional).
