5.12 CONTROLLER SECURITY & ALARMS
5.12.1 Password security
Controller features password security for setting of parameter. A valid password is an alphanumerical
code having minimum three and maximum eight characters.
Units leave the factory without a pre-programmed password and the security function is not active. To
activate the security, a password must be programmed. Once that is done, security can be enabled.

password was entered. When the ENTER key is pressed to change a parameter, the display will show a
message “Enter Password” on the top line and a blinking cursor on the right hand side of the bottom line.
Using INC and DEC keys scroll to the first character of the password and press ENTER. The character
will be substituted by an asterisk (*) displayed to the left of the cursor. Enter all characters of the
password the same way. If the password is less than eight characters long press ENTER again after last
