Becsys5 Installation And Technical Manual ^new^ Jun 2026

is a premier, workhorse solution for managing swimming pools, spas, and aquatic facilities. Offering precise, automated, and remote control of pH, ORP (chlorine), and temperature, this unit is designed to meet strict commercial water quality standards.

Accurate calibration guarantees that the controller's digital readings mirror actual pool chemistry conditions. Always perform manual wet chemistry tests (DPT-1 or FAS-DPD) using a calibrated professional photometer before adjusting the controller parameters. pH Calibration (Two-Point Method) Isolate the flow cell and remove the pH probe.

The BECSys5 represents a mature, robust solution for automated water chemistry management. By following the installation guidelines regarding NEMA 4X sealing and proper electrical supply, and by correctly programming the safety failsafe timers and communication parameters, facility operators can achieve significant chemical savings, regulatory compliance, and remote operational oversight.

The controller should be mounted securely to a wall or equipment pad. Ensure the location is clean, dry, and within an ambient temperature range that does not exceed the controller's specifications. Use the enclosure's mounting tabs to secure the unit in place with appropriate hardware (not supplied).

The BECSys5 features a backlit LCD with simple, intuitive navigation.

Plumb the sample inlet line after the main pool pump and filtration media, but before any chemical injection points or heating systems. Always perform manual wet chemistry tests (DPT-1 or
