Symptom
Problem
Possible Solution
Power center override switches
operate when in service or time
out mode, but the control panel is
completely dead (no lights on, no
display).
Power supply problem.
Check connection of the outside two wires (red
& green) of the four conductor cable. If wired
correctly, check the voltage between these two
wires. Voltage for an All button system should
be 7+ VDC and for a OneTouch system, 8+ VDC
(use the higher voltage for a mixed system).
All LEDs are on at the control
panel and the part # and revision
letter of the control panel soft-
ware are displayed. The override
switches at the power center
operate as they should.
Control panel is not commu-
nicating with the power center
PCB.
Check the two center wires (black & yellow) of
the four conductor cable. Also check the installa-
tion of the CPU Board on the power center PCB.
If the PPD is not seated correctly the system will
not communicate.
All LEDs are on at the control
panel and the part # and revision
letter are displayed, but override
switches at the power center do
not operate at all.
1. Damaged or improperly
installed CPU Board.
2. Damaged power center
PCB.
1. Check alignment of the CPU Board.
2. If CPU Board is installed correctly, replace
the power center PCB.
Some buttons do not operate
from the control panel, nor from
the power center override switch-
es.
Wrong CPU Board chip
installed at the power center
PCB.
Check part number and revision letter by press-
ing the reset button at the control panel. The
second part number and revision letter displayed
is for the CPU Board indicating which model.
System locked up.
Microprocessor locked.
Turn off power to the system and turn back on.
Programs do not run at the cor-
rect time.
AquaLink does not display cor-
rect time and date.
At the control panel set correct time and date.
One button on the Four Function
Remote or SpaLink
®
RS does not
operate.
Check programming first. If
the Four Function Remote or
SpaLink RS is programmed
correctly, the button may be
shorted.
Replace the Four Function Remote or SpaLink
RS. Use MENU, REVIEW, SPA SWITCH (or
SPA LINK) to check programming.
Pool cleaner booster pump turns
on without the filter pump being
on, and can run with the spa on.
System is not recognizing DIP
switch S1-1 is on. Note: before
turning on any DIP switches,
first turn off all equipment.
Turn off all equipment buttons, then turn off
power to the system, finally turn off, then on, DIP
switch S1-1. Turn on power and test system.
