8. User Lock Code Option [ULC]...continued:
A. Selecting ULC Option:
1) Press either the UP or DOWN ARROW keys; if “LOC” is momentarily displayed followed
by “0”, the ULC feature is enabled. If “0” displays proceed to “6)” of this section;
otherwise, see number “2,” below.
2) Simultaneously press and hold both the [UP ARROW] and [DOWN ARROW] keys until
[CF1] (Celsius / Fahrenheit) code appears.
3) Press the [POOL/SPA] key once to display [ULC].
4) With [ULC] displayed, pressing either the Up or Down Arrow key will display either “1” or
“0”. Selecting “0” will allow the keypad to remain unlocked. Selecting “1” will enable the
User Lock Code option. Then, to enter a lock code number, press the [POOL/SPA] key
once to display [ELC] (Enter Lock Code).
5) With [ELC] displayed, use the Up or Down arrow keys to select a lock code. The code
can be any number from “00” to “99”. The factory set lock code is “0”. Not pressing any
buttons for 15-seconds will allow the controller to save the selection and return to the
normal operating mode. Pressing the {POOL/SPA] key will also save the selection, and
will step the controller to the next menu parameter: [CFO] (Call Flex Options).
6) Once the ULC option has been enabled, pressing any key will momentarily display
“LOC” followed by “0” (prompting the entry of the correct lock code number). To gain
access to the controller:
a. Using the [UP ARROW] key, scroll to the correct lock code number, then;
b. Press the [POOL/SPA] key… Current water temperature will be displayed… Control
setting can now be viewed or changed as desired.
c. After a period of approximately four (4) minutes, during which time no buttons have
been pressed, the controller will automatically return to the locked mode. Provided
ULC selection is set to “1,” the controller will always fail-safe in the locked mode.
d. Without knowledge of the correct lock code, and with the ULC enabled, control
adjustments will not be possible. Be certain to record your lock code in a safe
place. The lock code may be changed any number of times by following the
instructions detailed in this section.
