Programming Procedure
You can set parameters in any order and as many times as you wish. To change a parameter use
the following command:
Parameter number parameter value
A three- digit parameter number is assigned to every parameter to be programmed and to every
memory (refer to the Programming Chart). This number indicates to 2N
®
Analog Vario which
parameter to change, and is used as "Enter". When it is entered, 2N
®
Analog Vario repeats
the parameter (or memory) number and reads the current contents (excluding passwords). Now
you can enter new data
– of variable meaning and length depending on the parameter selected
(refer to the Full Parameter Chart). Finally, press again for confirmation. 2N
®
Analog
Vario confirms the data saving. Repeat this procedure for each parameter.
Switch Password Programming
Each switch can be controlled with up to 10 different passwords that are listed in the 2N
®
Analog
Vario 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 2N
®
Analog Vario keypad. To cancel them, you have to remove them from the list:
or
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. 2N
®
Analog Vario 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 2N
®
Analog Vario 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.
