The Hayward 2100 Series Pool System Control is a sophisticated and user-friendly device designed to manage various aspects of a pool and spa environment. It offers comprehensive control over essential functions, aiming to provide a carefree lifestyle for pool and spa owners. The system is engineered for ease of operation and performance, allowing users to monitor, set, and control up to 12 functions for total pool and environmental management.
Function Description:
The Hayward 2100 Series acts as a central control unit for pool and spa systems. It integrates various components to automate and optimize pool operation. Key functions include:
- Temperature Control: The system allows users to set and maintain desired water temperatures for both the pool and spa. It includes sensors for water and air temperature, enabling precise climate control.
- Pump Management: It controls the filter pump, cleaner pump, and spa jet pump, offering options for single or two-speed operation where applicable. The system can be programmed for specific run times and cycles.
- Heater Control: The 2100 Series manages gas heaters, overriding their internal thermostats to ensure efficient heating based on user settings. It supports both millivolt and 24V control systems.
- Lighting Control: The system provides control over pool/spa lights and auxiliary yard lights. For 120V pool lights, it offers a dimming circuit with three selectable intensities.
- Motorized Diverter Valve Control: It manages motorized diverter valves to switch water flow between the pool and spa, or to direct water to other features like solar heating or water features.
- Freeze Protection: An integrated freeze protection feature automatically activates pumps and diverter valves when the air temperature drops to 35°F or lower, safeguarding pool equipment from damage. This feature is active only in pool mode.
- Optional Features: The system supports optional accessories such as pH/ORP sensors for water chemistry monitoring, a second master control panel, and RF wireless remote control panels for enhanced convenience.
- Expandability: With an optional expander circuit board, the system can manage additional auxiliary circuits, allowing for more complex pool and spa configurations.

Usage Features:
- Master Control Panel: The primary interface for users, typically installed inside the home at eye level. It allows for monitoring, setting, and controlling all system functions.
- Spa-Side Control Panel: An optional panel designed for convenient control from within the spa area. It is water-resistant but should not be submerged.
- Wireless Remote Operation: An optional RF remote control provides the flexibility to manage pool/spa functions from anywhere within a 100 ft. range of the Main Control Center, without hard-wired connections.
- Programming: The system offers extensive programming capabilities for filter pump cycles, spa operation, heating modes (Gas, Solar, Gas and Solar), auxiliary features, and lighting schedules.
- Temperature Display: Displays current water and air temperatures. Users can select between Celsius or Fahrenheit.
- Keypad Lock Feature: Allows users to lock all keypads on panels and remotes, except for the service panel, to prevent unauthorized changes.
- Error Messages: The LCD screen on the Master Control Panel displays troubleshooting messages (e.g., "OH" for high water temperature, "SN1" for water temperature sensor failure, "ICE" for freeze protection activated) to alert users to potential issues.
Maintenance Features:
- pH/ORP Sensor Calibration: The manual provides detailed instructions for calibrating pH/ORP sensors using a small flat head screwdriver to adjust a potentiometer on the pH circuit board. Regular calibration (at least monthly) with a test kit is recommended.
- Electrode Cleaning: Instructions are given for cleaning pH/ORP electrodes, including methods for soft coatings (water jet, wet cloth), hard coatings (acid/base solutions), and greasy/oil coatings (detergent, solvents).
- Winterization: Specific steps are outlined for winterizing the pH/ORP sensors, including disconnecting them, removing them from plumbing, reinserting them into a wetting cap filled with pool water, and storing them at room temperature.
- Troubleshooting Guide: The manual includes a troubleshooting section with common LCD messages and recommended actions, although it emphasizes that the system is not meant for consumer servicing and directs users to contact a local service person for electrical issues.
- Fuse Replacement: Spare fuses are available for various load circuits, and the manual notes that lower rated fuses may be necessary in certain applications to comply with the National Electrical Code.
The Hayward 2100 Series is designed to be a robust and adaptable control system, providing both convenience and safety for pool and spa owners through its comprehensive features and detailed installation and programming instructions.
