Compatibility and Buyer Check
This replacement board should be selected by exact part number, board layout, connection points, and model compatibility. Do not order only by product image because similar circuit boards may have different connectors or mounting locations.
If your issue is related to power supply operation rather than the control side, compare this part with the Zodiac R0512100 power PCB assembly before ordering. If the cell body or housing area is cracked or leaking, the Zodiac R0512000 pod housing replacement may be a better part to check first.
What This TS Control PCB Assembly Does
The TS control PCB assembly helps support control communication and operation inside compatible AquaPure Ei salt chlorine generator systems. A failed board may cause control issues, display problems, incorrect system response, or difficulty operating the generator properly.
Replacing the board may help restore normal control function when the rest of the system is still in good condition. It will not fix worn electrodes, cracked housings, plumbing leaks, incorrect salt levels, poor water chemistry, or damaged wiring outside the board area.
Before You Order
Check the following details before purchase:
- Confirm the exact part number R0512300.
- Verify your system model is APURE35, APURE35PLG, or another compatible AquaPure Ei model.
- Compare your existing board layout with the product image.
- Check connector style, cable position, and mounting holes.
- Inspect the power PCB, plug, housing, and electrode area for related damage.
- If the plug or sealing point is damaged, review the Zodiac R0511800 plug replacement.
- If the electrode assembly is worn or producing low chlorine, compare with the Zodiac R0511400 35 electrode replacement.
Installation Notes
Turn off all power to the salt water chlorine generator and pool equipment before opening the control area. If you are not trained to work around pool equipment wiring or circuit boards, use a qualified pool technician.
Install the replacement PCB in the same position as the original board. Do not force connectors, bend pins, overtighten screws, or allow moisture near the board. Before restoring power, confirm that all wires are seated correctly and no cable is pinched or loose.
Maintenance and Troubleshooting Tips
Keep the control area dry, clean, and protected from loose wiring or corrosion. During routine service, check the board area for signs of moisture, burnt marks, loose connectors, or cracked plastic supports.
If the system still does not operate correctly after replacing the board, inspect the power supply, sensor connections, electrode condition, salt level, and system settings before replacing additional parts.
