Switch Password Programming
Each switch can be controlled with up to 10 different passwords that are listed in the
Helios memory. Passwords can be added to the list using functions 811 and 821 and
deleted with functions 812 and 822 individually. The default status is a single password
in the list, namely 00 for switch 1 and 11 for switch 2. These two special passwords
cannot be entered from the Helios keypad. To cancel them, you have to remove them
from the list:
Function 997 deletes the entire password list for both switches including the
passwords 00 and 11. Function 999 deletes the entire password list for both switches
too but recovers the passwords 00 and 11 and the service password 12345.
Password Selection Restrictions
Controlling the switches by phone, you can enter the password without any starting
and terminating characters and the password length is not limited. Helios has to verify
after every character received whether the password is complete or not. Therefore:
make sure that no password is identical with the beginning of another password.
• Should you use such confusing passwords for switch control, you have to enter the
longer password (by phone) with asterisks at the beginning and end.
• If Helios refuses to store a password, it means that the switch password list is full,
or the password has already been entered.
• The switch password may not be identical with any Arrival/Departure, Day/Night, or
service password.
• For password selection tips see the Instructions for Keypad Use.
Deleting All Passwords, All Memories, Complete Initialisation
The following three functions facilitate your programming by clearing all previous
settings:
997 - deletes the entire password list for both switches including passwords 00 and 11.
998 - deletes memories of all buttons (01 - 54) plus Arrival/Departure and Day/Night
passwords.
999 - clears the whole memory and resets the default values (see the chart).
Protection against Unintentional Deletion
The above functions need no special parameter but must be protected against
unintentional initiation. Therefore, enter the service password as the function parameter.
Warning: Full initialisation takes a few seconds, Helios sends a continuous tone while
memory clearing. Functions 997 and 998 take a little less time and are signalled by a
continuous tone too.
The button memories can be deleted individually too – just enter a "blank" while
programming. For example:
or
clears memory 1 of button 01.
