to prevent unauthorized tampering or adjustment of the

Figure 53. Control Lockout
To unlock the controls, press MODE, UP or DOWN key
to bring up the ENTER PIN menu. Enter the PIN that
was used to lock the control. Note that power cycling will
not clear the lockout. Successfully unlocking the control
will display "LOCKBOX CLEARED". Failure to enter the
correct PIN will display "INVALID PIN".
In the event that the user-selected PIN is lost or does not
clear the Control Lockout, use the Program Menu to SET
FACTORY DEFAULTS. This will clear the PIN and allow
normal operation and selection of a new PIN if desired.
See the "Program Menu" section on page
31
for details.
NOTE:
By setting FACTORY DEFAULTS, both the POOL
and SPA setpoints will revert back to 65°F (18°C) and the
POOL and SPA maximum temperature settings will be
104°F (40°C). These setpoints will need to be readjusted
to desired settings. Other default configurations are also
applied.
