Section 1. Important Safety Instructions
READ AND FOLLOW ALL INSTRUCTIONS
Lire la notice technique.
All electrical work must be performed by a licensed electrician and conform to all national, state, and local codes.
When installing and using this electrical equipment, basic safety precautions should always be followed, including the
following:
WARNING
Prolonged immersion in hot water may induce hyperthermia. Hyperthermia occurs when the internal temperature
of the body reaches a level several degrees above the normal body temperature of 98.6° F. The symptoms of
hyperthermia include dizziness, fainting, drowsiness, lethargy, and an increase in the internal temperature of the
body. The effects of hyperthermia include: 1) unawareness of impending danger; 2) failure to perceive heat; 3)
failure to recognize the need to exit spa; 4) physical inability to exit spa; 5) fetal damage in pregnant women; 6)
unconsciousness resulting in a danger of drowning.
DANGER
To reduce the risk of injury, do not remove the suction fittings of your spa or hot tub. Never operate a spa or hot
tub if the suction fittings are broken or missing. Never replace a suction fitting with one rated less than the flow rate
marked on the equipment assembly.
WARNING
To Reduce the Risk of Injury -
a) The water in a spa should never exceed 104°F (40°C). Water temperatures between 100°F (38°C) and 104°F
(40°C) are considered safe for a healthy adult. Lower water temperatures are recommended for young children
and when spa use exceeds 10 minutes.
b) Since excessive water temperatures have a high potential for causing fetal damage during the early months of
pregnancy, pregnant or possibly pregnant women should limit spa water temperatures to 100°F (38°C).
c) Before entering a spa or hot tub, the user should measure the water temperature with an accurate
thermometer since the tolerance of water temperature-regulating devices varies.
d) The use of alcohol, drugs, or medication before or during spa or hot tub use may lead to unconsciousness with
the possibility of drowning.
e) Obese persons and persons with a history of heart disease, low or high blood pressure, circulatory system
problems, or diabetes should consult a physician before using a spa.
f) Persons using medication should consult a physician before using a spa or hot tub since some medication
may induce drowsiness while other medication may affect heart rate, blood pressure, and circulation.
WARNING
Risk of electric shock - Install the power center at least five (5) feet (152.4cm) from the inside wall of the pool
and/or hot tub using non-metallic plumbing. Canadian installations must be at least three (3) meters from the water.
Children should not use spas or hot tubs without adult supervision.
Do not use spas or hot tubs unless all suction guards are installed to prevent body and hair entrapment.
People using medications and/or having an adverse medical history should consult a physician before using a spa
or hot tub.
AVERTISSEMENT
Danger d'electrocution - Les installations canadiennes doivent se trouver à au moins trois (3) mètres de l’eau.
Ne pas laisser les enfants utiliser une cuve de relaxation sans surveillance.

CAUTION
A ground-fault circuit-interrupter must be provided if this device is used to control underwater lighting fixtures. The
conductors on the load side of the ground-fault circuit-interrupter shall not occupy conduit, boxes, or enclosures
containing other conductors unless the additional conductors are also protected by a ground-fault circuit-
interrupter. Refer to local codes for complete details.
CAUTION
A terminal bar marked "GROUND" is provided within the power center. To reduce the risk of electrical shock,
connect this terminal bar to the grounding terminal of your electric service or supply panel with a continuous
copper conductor having green insulation and one that is equivalent in size to the circuit conductors supplying this
equipment, but no smaller than no. 12 AWG (3.3mm). In addition, a second wire connector should be bonded with
a no. 8 AWG (4.115mm) copper wire to any metal ladders, water pipes, or other metal within five (5) feet (1.52m) of
the tub.
SAVE THESE INSTRUCTIONS
WARNING
People with infectious diseases should not use a spa or hot tub.
To avoid injury, exercise care when entering or exiting the spa or hot tub.
Do not use drugs or alcohol before or during the use of a spa or hot tub to avoid unconsciousness and possible
drowning.
Pregnant or possibly pregnant women should consult a physician before using a spa or hot tub.
Water temperature in excess of 100°F/38°C may be injurious to your health.
Before entering a spa or hot tub measure the water temperature with an accurate thermometer.
Do not use a spa or hot tub immediately following strenuous exercise.
Prolonged immersion in a spa or hot tub may be injurious to your health.
Do not permit any electric appliance (such as a light, telephone, radio, or television) within 5 feet (1.5 m) of a spa
or hot tub.
The use of alcohol, drugs or medication can greatly increase the risk of fatal hyperthermia in hot tubs and spas.
Water temperature in excess of 100°F/38°C may be hazardous to your health.
Attention installer: Install to provide drainage of compartment for electrical components.
WARNING
To avoid injury ensure that you use this control system to control only packaged pool/spa heaters which have built-
in operating and high limit controls to limit water temperature for pool/spa applications. This device should not be

Section 2. Control Panel Overview
2.1 Indoor Control Panel
The indoor control panel serves as a means of turning equipment on and off, entering programs to run equipment
automatically at selected times, and displaying what is going on in the rest of the system. Programs (and other
information entered through the controller) are stored in a memory chip on the power center board, even during a
power interruption (however long).
2.2 Controller
The power center supplies the controller 10 VDC via the two (2) outside wires (red and green) of the four (4)
conductor cables. If the voltage drops below 8 VDC, the display will flicker on and off. The two (2) inner wires
(yellow and black) provide the two-way communication link between the controller and the power center. They
communicate via serial communication, using signals like the standard "RS-485".
If either of the communication wires (inner pair) is broken or misconnected, but the power supply wires (the outer
pair) are connected properly, the controller will stop responding. It may show a steady screen of information, and stop
responding to its buttons. If power is then interrupted, the controller will lock up. The way it locks up will depend on
the type of controller.
1. Locked-up All Button. All LEDs will be on and the text will resemble the following: "6700 REV C".
2. Locked-up OneTouch. The screen will be covered with dots, with a line of text that resembles the following:
"Firmware Rev XXX".
2.3 Reset Switch
1. All Button Controller. Pressing the reset switch, located on the left side, will momentarily display the software
part numbers and revision letters for both the controller's micro controller chip and the power center's firmware
chip. The reset switch also resets the micro controller, but does not remove any programming, AUX labels, etc.
2. OneTouch Controller. The reset switch can be used to show the revision code for the firmware for both the
controller's micro controller chip and the power center's firmware chip.

3.2 Controller Troubleshooting
3.2.1 Display Is Not Illuminated
Check the voltage between the red and green wires at the red terminal bar (terminals 1 and 4). If the voltage is
between 8 and 10 VDC, check the polarity. The red wire is positive (+) and the green wire is negative (-). If the
voltage and polarity are correct, replace the control panel. If the voltage is less than 8 VDC, go to the power center.
1. At the power center, check the voltage between the red and green wires at the red terminal bar (terminals 1 and 4).
See Figure 5. If the voltage is between 8 and 10 VDC and the polarity is correct, but there is less than 7 VDC at
the indoor control, check the wires for the following:
a. Broken or shorted red or green wires.
b. Wire size. The minimum gauge for one control no more than 300 feet away from the power center is 22 AWG.
To ensure a lower drop in current, use larger wire (16 to 20 AWG)
2. If the voltage is less than 7 VDC, check the following:
a. Transformer secondary wires (two yellows). See Figure 6. If the voltage is less than 22 VAC, check the
incoming (primary power) to the system.
b. If the power to the transformer primary is less than 105 VAC, contact the power supply company.
c. If the voltage to the transformer primary is above 105 VAC, but the transformer secondary is less than 22
VAC, replace the transformer.
d. If the secondary voltage is 24 to 28 VAC, turn off the power.
e. Remove the fuse from its holder and do a continuity test. If there is no continuity, unplug all the Jandy Valve
Actuators (JVAs), replace the fuse (3.15 amp), and turn on the power. If the fuse blows with all JVAs unplugged,
the circuit board is damaged and needs to be replaced. If the fuse does not blow, plug a JVA cord into the Intake
JVA Socket. Test the JVA by switching to SPA. If the fuse holds, remove the tested JVA and plug the next JVA
into the Intake JVA Socket. Continue until all JVAs have been tested or the fuse blows.

3.2.2 Control Not Communicating with Power Center PCB
The following conditions indicate that the control is not communicating with the power center PCB:
1. All Button Control: All the circuit LEDs are illuminated and the display is locked on a part number and revision
letter.
2. OneTouch Control: The screen is covered with dots and displays a firmware version number.
Communication problems can be caused by the following:
1. Broken communication wire(s). These wires are connected to the red terminal bar at terminals two (2) and three
(3 ) (yellow and black). See Figure 7.
2. The microprocessor was hit by a power surge. Turn off all power to the system. (If the PCB is prior to Revision N,
disconnect the nine (9) volt battery.) Wait two (2) minutes and then turn the power on. If this frees up the system,
you will need to reset the time and date, except with a Revision N board. Programming will not be lost. It is
advisable to install a Surge Protection Kit.

3.3 Heater Operation
The pool and spa heater LED and the solar LED are two-color LEDs. Green indicates the heater is enabled but not on.
Red indicates the signal to the heater relay is being sent. A heater or solar LED will remain green for the following
reasons:
1. Thermostat setting has been reached.
2. Thermostat setting is below the water temperature.
3. Water temperature sensor has failed.
4. Other body of water is circulating (i.e., pool heater is enabled but spa is circulating).
To eliminate the control system as the cause of the heating problem, insert both wires to the heater into the same
terminal of the green terminal bar, as shown in Figure 8. If the heater does not operate, the problem is in the wires or
the heater, not the control system. Reinsert wires into the correct terminals after the test.

Section 4. Power Center
4.1 Overview
The power center PCB is the true brain of the system. The micro-controller on the PCB is constantly sending signals
through the communication wires to the control panel and polling the system to determine which circuits should be on
and which should be off.
4.1.1 Driver Chips
The driver chips can be thought of as a series of small relays. When one of the driver chips receives a signal, it closes
a contact which passes 24 to 32 VDC to the appropriate relay coil socket, in this case AUX 1. Each relay driver chip
activates a specific set of relay coil sockets (see the chart below). If a driver chip fails, it is usually caused by either
shorted relay coil wires, a shorted relay coil, or a relay not designed for the 24 VDC coil voltage (i.e., 24 VAC rather
than 24 VDC). The relay coil provides resistance (approximately 300 Ohms); if there is no resistance, the driver chip
circuit will be damaged.
4.1.2 Reset Button
Pressing the reset button, located in the upper left hand corner of the power center bezel, resets the power center
micro-controller. This also changes the time and date to the default settings for PCBs prior to Rev N. Pressing this
button will not remove any programming, AUX labels, etc.
4.1.3 EEPROM
All programming, labeling, temperature settings, etc., are stored within an EEPROM (Electronically Erasable Pro-
grammable Read Only Memory) chip. This chip is located on the PCB and will retain all settings indefinitely, even if
power is lost for an extended period. If the Power Center PCB is prior to Rev N, a 9-volt battery will keep the clock
running during power outages.
4.1.4 Battery
If the power is off for more than 34 hours, the battery will drain below 6.3 volts. This is insufficent to keep the clock
running, therefore, the date and time will be lost. If the PCB is Rev N or newer, a three (3) volt lithium battery will
keep the clock running during a power outage. If the line power is off for more than three (3) years, this battery may
drain to the point where it will no longer keep the clock running. Even if the battery is dead, the user inputs (Pro-
grams, Labels, Temperature Settings, etc.) will never be lost.

Page 15
4.2 Power Center Troubleshooting
4.2.1 Loss of Power
Check the power center transformer for the proper voltage.
1. Disconnect the transformer from the power center PCB. Check the voltage on the secondary transformer (the
two (2) outside yellow wires). The two (2) outside wires provide the 24 to 28 VAC to the PCB.
2. If there is less than 22 VAC at the secondary wires, check the voltage at the primary (black and white) wires for
105 to 130 VAC. If there is no voltage on the primary, check the supply source (the circuit breaker).
3. If there is 105 to 130 VAC on the primary and no voltage on the secondary, replace the transformer. Note: the
transformer and/or its fuse can be damaged by a short circuit. Water in the JVA can cause a short. A cut or spliced
JVA cord can cause a short. A damaged chip on the PCB (usually a driver chip) can cause a short.
Figure 9. Transformer Voltage Test
The two (2) outside wires provide the 24 to 28 VAC to
the PCB. The center wire is a ground. There is a four
(4) amp fuse between the secondary leads hidden
behind the transformer secondary cover.

Section 5. Auxiliary Power Center
5.1 Overview
An auxiliary power center provides control for systems that need to run more relays (and/or JVAs) than can be
handled by the main power center. The main one is still the central "brain" of the system; it sends control signals to
the auxiliary power center PCB through the 4-wire bus (red connector). Those control signals tell the auxiliary power
center which of its relays to turn on, and it provides the power for them. There are no temperature sensors or DIP
switches in the auxiliary power center, and it has no battery (as it depends on the time keeping that’s done by the main
power center).
5.1.1 Jumpers
Jumpers “W1” and “W2”: these are slide-on jumpers on the back side of the auxiliary power center board. They
identify the board and must be set correctly, or the board will not respond properly to commands from the main power
center PCB. (See below for jumper settings.)
5.1.2 Driver Chip
A driver chip (U6) drives the relays, just like the similar chips on the main power center. It is in a socket, to simplify
replacement in case of damage.
5.1.3 Switch
The left-most (bottom) switch on the auxiliary power center bezel works just like the one on the main power center,
changing from AUTO to SERVICE to TIME OUT (3 hour) and back to AUTO.
5.1.4 JVA Sockets
The (4) JVA sockets are driven together with the first (4) auxiliary relays here (they are not independent). Dimming:
use the second four (4) auxiliary sockets (B5 – B8) for light dimming relays, rather than the first four. (See section on
Light Dimming, later in this manual.)

5.2 DIP Switches
All DIP switches are located on the left side of the power center bezel. To change a setting, turn off the power and
move the approprate switch from left (OFF) to right (ON).
