Access Code
Setting the Access Code
User Function 01
The C4 controller has a single access
code that can be programmed. The
access code can be any number of
digits from 1 to 8.
This example would set a 4 digit
Access Code “1234”.
Key Switch Programming
Key switch programming makes
changing the access code very simple
and quick.
The C4 controller has an input labelled
“PRG”. This can be wired to a simple
key switch (Normally Open Contacts).
When the key switch is turned the
controller will take the next key
sequence as the new access code.
To remove an access code, see engineers function 98.
