Swimming Pool Automatic Control Panel & Systems Parts

Keep your pool's brain working perfectly with the right pool control panel parts and replacement components. From relay modules and surge protection kits to temperature sensors, timer mechanisms, and remote displays, PST Pool Supplies stocks the OEM and compatible parts needed to maintain Hayward, Zodiac, Jandy, Pentair, and Intermatic automation systems — with prices starting from just $9.90.

Whether you're replacing a failed relay, restoring surge-damaged electronics, or adding a new remote display, this collection covers it all. Key items include the Hayward OmniLogic 4-Relay and 1-Relay modules for expanding equipment control zones, Zodiac/Jandy temperature sensors for precise heating management, the Zodiac OneTouch outdoor enclosure, Compool 20A DPST relays, and Intermatic timer mechanisms and trippers. The Jandy AquaLink RS surge protection kit is an essential safeguard that protects your automation investment from lightning and power spike damage. For complete systems and upgrades, browse our pool automation systems collection. Hayward OmniLogic documentation and wiring diagrams are available at Hayward's official automation hub.

Identifying the correct pool control panel parts requires your automation system's model number — typically found on the main control board enclosure or in your original installation documentation. Most relay modules, sensors, and timer components are model-specific, so always verify compatibility before ordering. Our team can assist with part identification: contact us with your system model number and a description of the fault. For electrical installation standards, NEC Article 680 governs all pool control system wiring. Also see our pool electrical supplies collection for conduit, wire, and junction box components.

Shop pool automation control panel parts — and get your system back online fast with the right components for your brand and model.

Frequently Asked Questions

How do I find the right replacement part for my pool automation system?
Start by locating your automation system's model number — it's usually printed on a label on the main control board enclosure, the outdoor control panel, or in your original installation manual. Common systems include Hayward OmniLogic, Jandy AquaLink RS, Zodiac OneTouch, and Pentair EasyTouch. Once you have the model number, search by brand and model in our parts catalog. If you're unsure, contact our team with your system model and a description of the symptom — we can help identify whether the fault is in the relay module, sensor, timer, or circuit board before you order.
Why is surge protection important for pool automation systems?
Pool automation control boards contain sensitive electronics that are vulnerable to damage from lightning strikes, power surges, and utility voltage spikes. A single power event can destroy a control board costing hundreds of dollars. The Jandy AquaLink RS surge protection kit and similar devices clamp voltage spikes before they reach the board, extending the life of your automation investment significantly. Surge protection is especially important in regions with frequent thunderstorms or unstable utility power. We recommend installing surge protection on any automation system as a standard part of the initial setup — it's inexpensive insurance against a very costly failure.
What is a relay module and why would I need to replace it?
A relay module in a pool automation system is an electrically controlled switch that turns individual pieces of equipment on and off — pumps, heaters, lights, blowers, and water features each typically require their own relay. Relays can fail due to age, corrosion, power surges, or worn contacts, and a failed relay usually means one piece of equipment stops responding to the control system. The Hayward OmniLogic 1-Relay and 4-Relay modules allow you to replace individual relays without replacing the entire control system. Signs of a failed relay include equipment that won't turn on/off via automation but works when manually powered.
Can I add more equipment zones to my existing pool automation system?
Yes — most modern automation systems from Hayward, Jandy, and Pentair are expandable. Adding relay modules lets you control additional pieces of equipment — a second pump, a water feature, an air blower, or landscape lighting — from the same control system. The Hayward OmniLogic 4-Relay Module adds four new controllable zones in a single expansion module. Verify your system's maximum relay capacity and expansion slot availability before purchasing. Our pool automation collection also includes full system upgrades if your current controller has reached its expansion limit.
