FIRST OPERATING
7 FIRST OPERATING
To complete the start-up of the boiler, the following operations
are necessary, that should only be performed by an authorized
Service
R
:
− verification of the installation;
− slave board setting
− combustion analysis.
7.1 Slave board setting
This operation that should only be performed by an authorized
Technical Assistance Service
Each slave unit that composes the system should be identifia-
ble from the only master board, through an address that is as-
signed properly configuring the switches J10 and J17, on each
slave battery. Each slave (one for each burner) needs to be prop-
erly configured so that the Master board shall detect their right
sequence.
The slaves are divided into blocks of four slave each (every Con-
dexa Pro3 IN-EXT is a block) and the system can handle up to
15 blocks.
Therefore, the address configuretion is done for each slave us-
ing the following procedure, always remembering that a block
is equivalent to a unit:
− locate the block the slave is related to (ex. block n°1, n°2,
etc., till block n°15);
− locate the slave position inside each block (e.g. posi-
tion1,2,3 or 4);
− supply each Condexa Pro3 IN-EXT composing the battery
(see par.6.4.1).

Qualified personnel only may work on the electrical system
and in compliance to provisions of the law, with particular
attention to rules on safety.
As shown in Figure 24to set the address of the block you should
work on the switch located on the right (Jumper J17) and for
each slave (single burner) on the Left one (Jumper J10).
Refer to the table to see the possible combinations of the jump-
ers J10 that characterize the four slaves (n 1, 2, 3 and 4) of the
same block.

The data have to be used regardless of the number of units
present: if, for example, have 6 blocks in the battery we will
consider combinations until the line corresponding to the 6th
block, and not beyond.
In the following part is an example of configuration of a battery
with seven burner in cascade.
7.1.1 Example of configuretion of a battery with 7
burner in cascade
In case two blocks are present in an installation having a battery
of seven burners (i.e. seven slaves): the first is made of 4 burn-
ers and the second is made of 3. As a consequence, two blocks
need to be configured, respectively with address 1 and 2 and
with relative burners, to the first block with address 1,2,3 and 4,
and to the second block with address 1,2 and 3 (see Figure 25).
