Loading parameters with KEY
The "KEY" device allows the updating of combustion parameters for boiler type.
It is used to update the parameters or in case of circuit board replacement.
To update, disconnect the power supply, open the electrical box and insert the "KEY" device as per the instructions
provided with the kit (see also fig. 31). Close the electrical box and turn on the power to the boiler.
The display will show FH. If the system has not been drained, it is possible not to perform the "FH" phase by pressing
the button ref. 7 of fig. 1 for a few seconds. If the system has been drained, repeat the "FH" cycle.
