Selecting configuration level There are two alternative methods of selecting Configuration level:
• If you have already powered up, then follow the access instructions given in Chapter
3, Access levels.
Alternatively, press and together when powering up the controller. This will
take you directly to the ‘ConF’ password display.
Password entry
When the ‘ConF’ display appears, you must enter the
Configuration password (which is a number) in order to gain
access to Configuration level.
Enter the password using the or buttons.
The configuration password is set to ‘2’ when the controller
is shipped from the factory.
Once the correct password has been entered, there is a two
second delay, after which the lower readout will change to
‘PASS’ indicating that access is now unlocked.
Note: A special case exists if the password has been set to
‘0’. In this situation, access is permanently unlocked and the
lower readout will always show ‘PASS’.
Press to enter configuration.
(If an incorrect password has been entered and the controller
is still ‘locked’ then pressing at this point will take you
to the ‘Exit’ display with ‘no’ in the lower readout. Simply
press to return to the ‘ConF’ display.)
You will obtain the first display of configuration.
