Hayward CAT 2000 Professional Package
The Hayward CAT 2000 Professional Package constantly monitors pH and sanitizer activity — including chlorine, bromine, and salt systems — and automatically implements chemical feeding in proportion to demand for picture-perfect water quality at all times.
Built with a digital microprocessor-based design with flash technology, advanced proportional feed control, weatherproof membrane switch interface, and comprehensive alarm systems for flow, pH, and ORP. Compatible with all types of chemical feed equipment. Includes machined acrylic flow cell and rotary flow sensor. Backed by a 5-year controller warranty and 2-year sensor warranty.
Key Features
Automatic pH and ORP Control
Continuously monitors and automatically doses chemicals proportional to demand — chlorine, bromine, and salt systems supported.
5-Year Controller / 2-Year Sensor Warranty
Best-in-class warranty coverage — 5 years on the controller, 2 years on sensors.
Proportional Feed Technology
Advanced proportional feed adjusts dosing rate based on how far the reading is from setpoint — maximizes precision and efficiency.
Salt-Chlorine System Dry Contact Outputs
Dry contact outputs specifically provided for salt-chlorine generator control.
Comprehensive Alarm System
Flow alarms, ORP high/low alarms, pH high/low alarms, pH priority feed, and supplemental feed modes.
Weatherproof Front Panel
Membrane switch interface with weatherproof construction for outdoor equipment pad installation.
Flash Technology
All factory settings permanently stored in memory — retains programming through power interruptions.
Flow Cell and Sensor Included
Machined acrylic flow cell and rotary flow sensor included in the Professional Package.
Universal Chemical Compatibility
Compatible with all types of chemical feed equipment.
LED Display
Easy-to-read LED display with manual, automatic, on/off, feed, pH, and ORP mode selections.
Who It's For
- Commercial pool and fountain operators who want automated pH/ORP control with a 5-year controller warranty
- Facilities running chlorine, bromine, or salt-chlorine systems
- Anyone who wants proportional feed technology and comprehensive alarm protection

Frequently Asked Questions
What is the difference between the CAT 2000 Professional Package and a standard chemical controller?
The "Professional Package" designation means the machined acrylic flow cell and rotary flow sensor are included — saving the purchase of these components separately. The CAT 2000 controller itself also carries a standout 5-year warranty on the controller (vs. 1-2 years on most competitors) and 2 years on sensors, reflecting its commercial-grade durability.
What sanitizer types does it support?
The CAT 2000 is compatible with all common pool sanitizer types — chlorine feeders, bromine feeders, and salt-chlorine generators (via dedicated dry contact outputs). It also works with CO2 systems for pH reduction.
What is flash technology?
Flash memory stores all factory settings and user programming in non-volatile memory — meaning the controller retains all its settings through power outages or interruptions without needing to be reprogrammed.
What does pH priority feed do?
pH priority feed mode temporarily pauses sanitizer dosing while pH adjustment is in progress, preventing interference between chemical additions. This improves accuracy and prevents chemical interactions during correction cycles.
