LCD DISPLAY ELEMENTS

PROGRAM BLOCK FORMATION
The purpose of the blocks is to simplify the program-
ming, i.e. switching
times
that are the same for differ-
ent holidays or periods need not be repeated.
Likewise, when programming ON and OFF times the
date need only be entered once.
The time switch assigns a block number from 00 to 99
to each program with dates entered. All programs
without a date (7-day programs) automatically receive
the block number 00.
Programs with dates – individual days or periods of
days – are assigned an ascending block number (01,
02...99). All programs within a block are stored by
pressing “N”. The last program or portion of a pro-
gram within a block is entered by pressing “S”, thus
closing the block.
Execution of Programs
At beginning of each day the microprocessor deter-
mines which of the stored programs for that day have
the highest priority. Only the highest priority
program(s) will be executed.
Once the Digi 322 is programmed, it will automatically
“look back” and assume the correct ON or OFF switch
position.
PRIORITY
The microprocessor automatically assigns the lowest
priority – “0” – to standard 7-day programs.
Holiday programs with a duration of more than one
day automatically receive priority “1”.
Holiday programs for one day only automatically
receive priority “2”.
A higher priority can be manually assigned to any holi-
day program by using the “Prior.” key.
PROGRAM STORAGE CAPACITY
The Digi 322 can store up to 322 programs. These
322 programs can be freely assigned to different
dates or periods, switching times or channels. A stor-
age position is used each time the button “N” or “S” is
pressed. If all 322 storage positions are used up, four
8’s will be shown in the display.
If a program step is not complete and storage is
attempted with the “N” or “S” button, the missing com-
ponents will blink in the LCD.
