Page 4 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: DANGER To reduce the risk of injury, do not remove the suction fittings of your spa or hot tub.
Page 5 Page 5 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.
Page 6: Section 2. Control Panel Overview
Page 6 Section 2. Control Panel Overview 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).

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.

Page 13: Heater Operation
Page 13 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.
Page 14: Section 4. Power Center
Page 14 Section 4. Power Center 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.
Page 15: Power Center Troubleshooting
Page 15 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.

Page 18: Section 5. Auxiliary Power Center
Page 18 Section 5. Auxiliary Power Center 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).

Page 21 Water Temperature Sensor 5.3.1 Troubleshooting When the Power Center PCB is put in Service or Time Out Mode, the thermostat setting will automatically be switched to 104° F for testing. If the heater circuit is activated and the water heater temperature is less than 104° F, the LED above the heater button should turn on.

Page 23: Hp Relay
Page 23 3 HP Relay 5.4.1 Operation 1. A standard 3 HP Relay's coil is supplied with 24 VDC from the power center PCB via one (1) of the driver chips. When 24 VDC is received by the relay's coil wires, it closes the contacts that complete the circuit to turn on the equipment (i.e., power supplied to Line 1 goes out Load 1 to the equipment).

Page 25: Two Speed Relay
Page 25 Two Speed Relay 5.5.1 Operation The two speed relay operates in conjunction with a standard relay to operate a two speed pump/motor. The standard relay is the on/off relay and the two speed relay is the switching relay. Activating the relay coil for the standard relay will complete the contact circuit between Line 1 and the motor common, Line 2 and the two speed relay common.

Page 27: Light Dimming Relay
Page 27 Light Dimming Relay 5.6.1 Operation The controller signals the light dimming relay to turn "fully on", "partially dimmed", or "completely off" by sending a speciﬁ c number of pulses in a set period of time to the light dimming relay. The circuitry of the light dimming relay, which requires 120 VAC to operate, interprets the number and timing of pulses to determine whether the light should be on, off, or dimmed.
Page 28 Page 28 Speciﬁ cations Voltage: 12 to 120 VAC Wattage: 1000 maximum Note: a maximum of four (4) light dimming relays can be installed in each power center. Note A Standard Relay can be mounted (piggybacked) on top of the Dimmer Relay to allow for a total of eight (8) Relays in Power Center.
Page 29: Section 6. Jandy Valve Actuator
Page 29 Section 6. Jandy Valve Actuator Operation One leg of a 24 VAC transformer secondary supplies voltage to the common terminal of a SPDT (single-pole, double- throw) relay. The N.C. (normally closed) terminal of that relay is connected to the red wire of the JVA cord, and the N.O.
