15.9 - How to move a control board
100 to 140 model appliances are configured to be managed
by a control board (Burner 1 Master). All the devices are
connected on this board: room thermostat, external probe,
pump controls, external safety devices and all the internal
safety devices: condensate level sensor, flue exhaust
differential pressure switch, etc.
If the Burner 1 control board has an error, the appliance stops
working. If the technician does not have spares to replace
the board, he/she can temporarily replace it with one of the
boards from another burner in the appliance so that the latter
can be restarted.
To this end, proceed as follows:
(when not otherwise specified, refer to figure 15-10):
1. Turn off the main switch and disconnect power;
2. Access the inner components following what is described
in section 15.2;
3. Disconnect connector “B” (connector coming from the
display) to connector “A” (connector coming from “Burner
1 (Master)”);
4. Disconnect all the other connectors from the Burner 1
(Master) control board;
5. Remove the Burner 1 (Master) control board from the
appliance;

6. Follow points 3 to 5 to remove the control board from the
burner positioned lower;
7. Assemble the board in place of the Burner 1 (Master) board;
8. Restore all the connections in the new Burner 1 (Master)
board;
9. Move selector “S4” as shown in figure 15-11 from the OFF
position to the new ON position;
10. Be very careful with the connectors from the board that
was removed. They must be insulated to avoid short circuits
and damage;
11. Electrically insulate each of these connections;
12. Replace the appliance casing;
13. Reconnect power and turn on the appliance main switch;
14. Access the forced menu, follow section 17 and set all
the parameters as per the “Burner 1 (Master)” column.
