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.
