CHEMTROL® PC3000 Programmable Controller

Engineered for professional pool and spa operations, the CHEMTROL® PC3000 brings chemistry control and equipment automation into one intelligent panel. It continuously monitors pH and sanitizer (ORP) for stable, code-compliant water, then drives your chemical feed (pumps/valves) with adjustable setpoints, proportional dosing, and safety timeouts to prevent overfeed. Beyond water balance, the PC3000 coordinates key equipment—filters, pumps, heaters, lights, and auxiliaries—so scheduling, interlocks, and backwash sequences run the same way every time, without constant oversight.

Day-to-day use is streamlined: a bright front panel shows real-time readings and alarm status at a glance, while programmable relays and alarm contacts make it easy to integrate with existing pumps, feeders, and safety circuits. Optional data logging and remote access (where configured) let operators review history, verify compliance, and make informed adjustments from the office—cutting site visits and downtime. The result is clear, comfortable water with fewer surprises and a more predictable operating cost.

Key highlights

• Continuous pH & ORP monitoring with adjustable setpoints and overfeed protection

• Programmable relays for chemical feed and auxiliary equipment (heater, lights, valves)

• Support for timed/logic sequencing (e.g., coordinated backwash and pump/heater interlocks)

• Alarm outputs and clear on-panel status for fast troubleshooting

• Optional logging/remote supervision (where equipped) to track trends and optimize dosing
