The parameters related to this function are the following:
P.0421: allows to specify in which days of week the engine can start automatically. It
is a bit-configurable parameter; each bit of the parameter corresponds to a day of the
week. The value to be set for the parameter is the sum of the value fields in the
following table related to the days needed.

P.0422: allows to configure the start of the time interval during which the engine can
start automatically (in hours and minutes).
P.0423: allows to configure the end of the time interval during which the engine can
start automatically (in hours and minutes).
Usually P.0422 will be set to a value lower than P.0423. On the contrary, if it contains a higher
value, the controller infers that the time interval is set across midnight: in this case, the time
set with P.0422 refers to the days selected with P.0421, while the time set with P.0423 refers
to the following days.
For example, in case an automatic gen-set start is required only Monday through Friday,
between 08:00 and 18:00, you must set:
P.0421 = 62 (2+4+8+16+32)
P.0422 = 08:00
P.0423 = 18:00

The controller has a non-volatile memory inside (which does not need power), used to store
various information such as parameters, counters etc. The memory is divided into different
zones. When the controller is powered, it performs a check on the data stored in each area: if
even just one area is incorrect, it displays an error message; this can happen after a FW
update. Said message contains a numerical code (in hexadecimal form); each bit to 1 of said
code corresponds to an area of the memory that is not valid. Here is a table listing the areas
and their bit.
