16.9 - How to move a control board
Appliance models from 100T to 280T are set up to be managed
by a control board (Burner 1 Master). All the devices are
connected to this board: room thermostat, external sensor,
pump commands, external safety devices, and all internal
safety devices: condensate level sensor, exhaust gases
differential pressure switch, etc.
If the Burner 1 control board has an error, the appliance stops
working. If the technician does not have the parts to replace
the board, he can temporarily replace it with the board from
one of the other burners present on the appliance, in order
to restart it.
To do this, proceed as follows:
(refer to Figure 16-10 unless advised otherwise)
1. Turn off the general switch and disconnect the electric
power supply;
2. Follow the steps of section 16.2 to access the internal
components;
3. Disconnect connector “B” (the connector that comes from
the display) from connector “A” (the connector that comes
from “Burner 1 (Master)”);
4. Disconnect all the other connectors from Burner 1 (Master)’s
control board;
5. Remove the control board of Burner 1 (Master) from the
appliance;

SELECTOR SWITCH S4
6. Follow points 3 to 5 to remove the control board from the
burner located lowest down;
7. Fit the board in place of that of Burner 1 (Master);
8. Restore all the connections to the new Burner 1 (Master)
board;
9. Move selector switch “S4” as shown in figure 16-11, from
the OFF position to the new ON position;
10. Take great care with the connectors of the board that’s
been removed. They must be isolated to avoid short circuits
and damage;
11. Isolate each of these connections electrically;
12. Replace the appliance casing;
13. Reconnect the electric power supply and turn on the
appliance’s general switch;
14. Access the forced menu, follow the steps of section 18 and
set all the parameters as shown in the “Burner 1 (Master)”
column. Parameter
3050
must be reduced by one unit
compared to the previous status, because the appliance
now has one Slave Burner fewer.
15. Interrupt the electric power supply;
16. Reconnect the appliance’s electric power supply. Now
Burner 1’s new control board is controlling the appliance.
