Manual PCB for all C series Clearwater Chlorinators

Meet the Manual PCB designed for the entire family of Clearwater Chlorinators in the C-series lineup. This drop-in replacement brings back precise, hands-on control to your chlorine generation, with a compact, purpose-built board that speaks the language of your system’s original hardware.

Key compatibility and fit

Engineered to retrofit Clearwater Series Chlorinators across all C-series models, including the early C, B, BH, HS, TS, QC, and the Bluehaven Hydromaster control enclosures. The new blue socket connection ensures a secure, reliable link to the corresponding controller harness, reducing misalignment and connection wear common with aging boards. Compatible with brown and white backup boxes that house these models, making it an ideal upgrade path for legacy units.

What makes this PCB stand out

• Manual control pot provides intuitive, tactile adjustment of chlorine output, giving you precise dosing without relying on automated cycles.
• Three status LEDs offer at-a-glance diagnostics—quickly confirm power, activity, and fault states to troubleshoot without guesswork.
• New blue socket delivers a solid,米 snug connection to your control harness, improving reliability over time and simplifying installations.
• Generic PCB construction designed as a versatile replacement across multiple Clearwater C-series configurations, reducing the need for multiple specialized boards.

Who this is for

• Pool owners and service techs seeking a dependable manual-control retrofit for aging Clearwater chlorinators.
• Facilities with brown or white control enclosures that need a straightforward, compatible replacement board.
• Anyone aiming to regain direct, adjustable chlorine generation without jumping to a full automation overhaul.

Use cases and benefits

Whether you’re balancing chlorine output for seasonal pool use or maintaining steady sanitizer levels in a busy backyard oasis, this manual PCB lets you tailor dosing to real-world conditions. Use it to:

• Restore manual dosing after a faulty automatic controller failure.
• Fine-tune chlorine generation during variable weather, heavy swimmer load, or high bather days.
• Extend the life of existing Clearwater systems by replacing aging control electronics instead of replacing the entire unit.

Installation and tips

For a smooth retrofit, power down the chlorinator and disconnect the power supply before handling the PCB. Align the new blue socket with the controller harness, seat the board firmly, and set your desired chlorine output using the control pot. Use the LEDs as a quick health check after power restoration to confirm the board is communicating with the rest of the system.

What’s included

• Manual PCB for all C-series Clearwater Chlorinators
• Control potentiometer (pot)
• Three indicator LEDs
• New blue socket connector
• Compatibility coverage for early C, B, BH, HS, TS, QC, and Bluehaven Hydromaster boxes

Maintenance and care

Periodically inspect the blue socket and solder joints for signs of wear or corrosion, especially in humid pool environments. Keep the enclosure dry during maintenance, and reseat the PCB if you notice intermittent LED activity or unstable readings. Regular checks help ensure reliable manual control and consistent chlorine generation over time.

Why choose this retrofit

This Manual PCB is purpose-built to restore hands-on control to Clearwater C-series systems with specificity and reliability. It consolidates compatibility across multiple model families, simplifies replacement with a single, versatile board, and adds clear diagnostic LEDs along with a robust blue socket connection. If you want direct control over chlorine dosing without sacrificing compatibility with legacy enclosures, this is the targeted, practical solution you’ve been seeking.
