Ariston 28 MFFI - Manual (Page 8)

Begin any further entry of a switching time with the “Prog” switch. If your
entry is incomplete, the segments not yet selected will blink in the
display. After programming is completed, and you return the time clock
to the current time display with the “ ” key, the time clock will not
activate any switching instruction required for the current time. You may
need to manually select the desired switching state with the “ ” key.
Thereafter, as the unit encounters further switching instructions in the
memory in real time, it will correctly activate all subsequent switching
instructions.
Manual Override Switch “ ”
With the “ ” you can change the current setting at any time. The switching
program already entered is not altered.
Reading the programmed switching times
Pressing the “Prog” key displays the programmed switching times until the
first free memory location appears in the display “– – : – –”.
If you now press the “Prog” key once again, the number of free memory
Iocations will be displayed, e.g. “18”. If all memory locations are occupied,
the display “00” appears.
Changing the programmed switching times
Press the “Prog” key repeatedly until the switching time you want to change
is displayed. You can now enter the new data. See point “Entering the
switching times”.
Notes on storing switching times:
If you end your entry of the switching times by pressing the “Prog” key, then
the switching time you have entered will be stored and the next memory
location displayed.
In addition, a complete switching command is stored automatically after
around 90 seconds provided no other key is pressed. The time switch then
enters the automatic operating mode and displays the current time again.
Deleting individual switching times
Press the “Prog” key repeatedly until the switching time you wish to delete
is shown in the display. Then set to “– –” using the “h” or “m” key and keep
the “ ” key pressed down for around 3 seconds. The switching time is now
erased and the current time is displayed.
AM / PM time display
If you press the “+/-1h” and “h” keys at the same time, the time display
switches into the AM/PM mode.
