Selecting ULC Option (Continued):
4) With [ULC] displayed, pressing either the Up or Down arrow key will display either
(1) or (0). Selecting (0) will allow the control 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. [ELC] (Enter Lock Code) will display;
5) With [ELC] displayed, use the Up or Down arrow keys to select a lock code
number. The factory set lock code is “17”. Not depressing any buttons for 15-
seconds will allow the control to save the selection and return to the normal
operating mode. Pressing the Pool / Spa key will also save the selection and step to
the next menu parameter [CFO] (Call Flex Options);
6) Once the ULC option has been enabled, depressing any key will display [000]
(prompting the entry of the correct lock code number). To gain access to the
controller:
a) Using the Up
arrow, scroll to the correct lock code number, then:
b) Press the Pool/Spa selector button…Current water temperature will be
displayed… Control settings can now be viewed and 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 the ULC selection is “1”, the controller will always
fail-safe in the locked mode.
d) Without knowledge of the correct lock code number, with ULC enabled,
control adjustments will not be possible. Be certain to record your
security code in a safe place. The lock code number may be changed any
number of times by following the instructions detailed above in this section.
B. User Lock Code is Activated, but Pass Number is Not Known (“Back Door Entry”):
NOTE: Should the ULC option be enabled, and a lock code number other than the
factory default (17) be installed but is unknown, the following procedure
may be followed to re-gain controller programming access:
1) Turn off power to the heater at the breaker;
2) Simultaneously press and hold down the Up & Down arrows;
3) Continue holding arrow buttons down while turning the power back on;
4) Keep holding arrows down for approximately 15 seconds;
5) [CF1] will appear;
6) Go to [ELC] by pushing the Pool/Spa button. (Display will change each time P/S
button is pushed.);
7) Go to the up arrow, push it once. (The number that appears is the present, valid lock
code number);
8) It is recommended the access code be returned to the factory default: “17”, before
exiting the program. By going back to [ELC] you can use the Up/Down arrows to
reset the lock code number back up or down to “17”.
