Technical Guide • Updated March 2026
Jandy AquaLink RS Wiring Guide

Quick Summary

  • The AquaLink RS Power Center contains the PCB, RS transformer, relays, and all wiring connections. It receives 120 VAC input and provides both high-voltage switching and 24 VAC low-voltage control.
  • The green 10-pin terminal bar handles all sensor and heater low-voltage connections. Terminals are numbered 1-10 from right to left.
  • Relay sockets are labeled on the PCB: Pool Pump (far left), AUX 1-6, Spa Pump (far right after AUX 6).
  • JVA sockets for valve actuators: Intake, Return, Cleaner, and Solar JVA.
  • The control panel connects via a multi-conductor cable. Strip the jacket back 6 inches, strip each wire 1/4 inch, and wire per the diagram on the Power Center door.

Safety Warning

All electrical work must be performed by a licensed electrician and conform to NEC, CEC, and local codes. Disconnect all power at the circuit breaker before working inside the Power Center. The Power Center must be installed at least 5 feet (152.4 cm) from the inside wall of the pool or spa. Canadian installations require at least 3 meters. Never run high-voltage and low-voltage cables in the same conduit.

Power Supply Connection

  1. The Power Center receives 120 VAC from the main electrical panel through a dedicated circuit breaker.
  2. Wire nut the incoming 120 VAC power to the system power connection inside the Power Center.
  3. The RS transformer converts 120 VAC to 24 VAC for the control circuit. The orange 24 VAC power plug from the transformer plugs into a 3-pin terminal on the back of the Low Voltage Bezel (PCB).
  4. A ground terminal bar marked "GROUND" is provided. Connect it to the grounding terminal of your electrical service with a continuous green-insulated copper conductor, no smaller than #12 AWG.
  5. A #8 AWG copper bonding wire must connect to any metal ladders, water pipes, or other metal within 5 feet of the pool or spa.

Green 10-Pin Terminal Bar

The green 10-pin terminal bar is the central connection point for all low-voltage sensor and heater wiring. Terminals are numbered 1-10 from right to left. The exact pin assignments are shown in the wiring diagram on the inside of the Power Center door (Section 5, Figure 5 in the manual).

Sensor connections

  • Water temperature sensor: Connects to designated terminal pair on the 10-pin bar. The sensor installs in a 3/8" hole between the filter pump and filter with the provided clamp and O-ring.
  • Freeze/air temperature sensor: Connects to designated terminal pair. Install outdoors in ambient air, not in direct sun.
  • Solar temperature sensor (optional): Connects to pins 7 and 8. Install adjacent to solar panels. Requires S1 DIP #7 ON.

Heater connections

  • Pool heater: Two #14 gauge wires (rated for hot environments) connect from the designated heater terminals to the heater, wired in series with the heater's fireman's switch connection.
  • Spa heater: Connects via the Spa Heater Interface Board, which plugs into the Spa Heater socket on the PCB.
  • Factory wire loop: Terminals 1 and 2 have a factory-installed wire loop that must be removed before connecting heater wires.

Relay Socket Layout

The PCB has labeled sockets for plug-in relays. Each socket provides 24 VDC output to energize the relay coil when the corresponding equipment is commanded on.

Socket Position Function Notes
Far left Pool Filter Pump Always the leftmost socket
AUX 1 Auxiliary 1 / Cleaner (if S1 DIP #1 ON) Cleaner mode adds 3-min delay and auto-off behaviors
AUX 2 Auxiliary 2 / Low Speed (if S1 DIP #2 ON) Requires Jandy Two-Speed Relay for 2-speed operation
AUX 3 Auxiliary 3 / Spillover (if S1 DIP #3 ON, dual) Leave socket empty when spillover is enabled
AUX 4-6 Auxiliary equipment General purpose relay sockets
After AUX 6 (far right) Spa Filter Pump Dual equipment systems only
Additional sockets Solar Pump, Spa Heater Per wiring diagram

JVA (Valve Actuator) Sockets

Jandy Valve Actuators plug into dedicated 24 VAC output sockets on the PCB:

  • Intake JVA: Controls the intake valve for pool/spa switching
  • Return JVA: Controls the return valve for pool/spa switching
  • Cleaner JVA: Controls the cleaner line valve
  • Solar JVA: Controls the solar diverter valve

Do not coil excess JVA cable inside the Power Center. To shorten the cable, remove the JVA lid, disconnect the cable, cut to length, strip, and reconnect. Run JVA wires through the low-voltage raceway.

Control Panel Cable

  1. The Jandy Control Panel Cable is a multi-conductor cable that runs between the wall-mounted control panel and the Power Center.
  2. If the cable will run underground or through concrete, it must be in conduit. Never run high-voltage and low-voltage cables in the same conduit.
  3. At the Power Center end, pull the cable into the low-voltage compartment. Strip back the cable jacket 6 inches. Strip each individual wire 1/4 inch.
  4. Wire each conductor to the PCB according to the wiring diagram in Section 5, Figure 5 of the manual. The terminal bars are labeled: "To Controller," "To Remote," and "To Sensors, etc." with associated wire color codes.

Additional PCB Connections

  • Service Controller Connector: Connects to the main controller for diagnostics.
  • Multiplex PCB Connector: For optional multiplex board connection (expands system capabilities).
  • Grounding Bar: All ground connections terminate here. Must be bonded to the building ground per code.
  • System Power: 120 VAC input connection point.
  • Low Voltage Raceway: Compartment for routing low-voltage wiring. Keep low-voltage and high-voltage wiring separated.

Grounding and Bonding Requirements

  • Connect the "GROUND" terminal bar to the grounding terminal of your electrical service panel with a continuous green-insulated copper conductor no smaller than #12 AWG (3.3mm).
  • Bond with a #8 AWG (4.115mm) copper wire to any metal ladders, water pipes, or other metal within 5 feet (1.52m) of the pool or spa.
  • If the system controls underwater lighting, a ground-fault circuit-interrupter (GFCI) must be provided. Load-side conductors of the GFCI must not share conduit or boxes with unprotected conductors.

  • All Button Control Panel: 8" x 5" x 1.25"
  • OneTouch Control Panel: 4.5" x 4.5" x 1.25"

  • Sub-Panel Power Center: 14.5" x 5" x 20" (6" depth for PureLink models)

Frequently Asked Questions

Can I extend the control panel cable?

Yes, but use the same gauge wire and make reliable splices (soldered and heat-shrunk, or appropriate low-voltage splice connectors). Keep the cable in conduit if underground. The longer the cable run, the more susceptible it is to voltage drop and interference.

What breaker sizes are compatible with the Sub-Panel Power Center?

The Sub-Panel model accepts breakers from several manufacturers including Cutler-Hammer (BR series), Murray (MP-T series), Siemens (QP series), Square D (HOM series), and Thomas & Betts (TB series). Refer to the compatibility chart in Section 2.2 of the manual for exact model numbers.

Where can I find the wiring diagram for my specific system?

The wiring diagram is printed on the inside of the Power Center door. It is also shown as Figure 5 in Section 5 of the installation manual. The diagram shows all terminal assignments, relay sockets, JVA sockets, DIP switches, and wire color codes.

How do I identify which relay goes where if they were all removed?

The PCB silkscreen labels each relay socket. Pool Pump is on the far left, AUX 1-6 are in sequence, and Spa Pump is on the far right after AUX 6. All 3HP relays are physically identical and interchangeable between sockets.
