P.0426: allows to specify in which days of week the engine is forced to 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.0427: allows to configure the start of the time interval during which the engine is
forced to start automatically (in hours and minutes).
•
P.0428: allows to configure the end of the time interval during which the engine is
forced to start automatically (in hours and minutes).
Usually P.0427 will be set to a value lower than P.0428. 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.0427 refers to the days selected with P.0426, while the time set with P.0428 refers
to the following days.
For example, in case an automatic gen-set start must be forced only on Monday through
Friday, between 08:00 and 18:00, you must set:
P.0426 = 62 (3E in hexadecimal format) (2+4+8+16+32)
P.0427 = 08:00
P.0428 = 18:00
The controller provides 16 calendars fully configurable. They allow to select days and time-
slots, inside which the controller activates an internal bit. This bit could then be used by
AND/OR logics to activate a digital output or to create more complex logics. All calendars are
identical: calendars 15 and 16, however, can be used for the activation/deactivation of the
daylight save time (if parameter P.0409
is set to “3”).
Each calendar can be individually selected as “monthly” or “weekly”:
