• PF LIMITS: Pressure/Flow limit switch connections.
• SENSORS: Various sensor inputs for monitoring heater conditions.

Installation Instructions

1. Power Disconnection: Turn off all electrical power to the heater at the main circuit breaker before beginning installation.
2. Access the Control Board: Open the heater's control panel access cover. Refer to your heater's specific manual for instructions on accessing the existing control board.
3. Document Connections: Before disconnecting any wires, take clear photographs or make detailed diagrams of all existing wire connections to the old control board. Note the color and position of each wire.
4. Remove Old Board: Carefully disconnect all wires and connectors from the old control board. Remove any mounting screws or clips securing the old board.
5. Install New Board: Position the new Hayward IDXL2ICB1931 control board in the heater's enclosure. Secure it using the original mounting hardware or the new plastic standoffs provided with the replacement board, if applicable.
6. Reconnect Wiring: Using your photographs or diagrams, carefully reconnect all wires and connectors to their corresponding terminals on the new control board. Ensure all connections are secure and properly seated.
7. Verify Connections: Double-check all wiring against your documentation to ensure accuracy. Incorrect wiring can cause damage to the board or heater.
8. Close Access Cover: Once all connections are verified, close and secure the heater's control panel access cover.
9. Restore Power: Restore electrical power to the heater at the main circuit breaker.
10. Initial Startup: Follow the initial startup procedures outlined in your heater's main instruction manual. Observe the heater's operation for any error codes or unusual behavior.

Note: The new control board may come with a conformal coating for enhanced durability, which may differ from older boards. This is a design improvement.

Operating Instructions

The Hayward IDXL2ICB1931 Integrated Control Board functions as the brain of your heater. Once installed, its operation is integrated with the heater's overall system. Refer to your specific Hayward H-Series heater's user manual for detailed operating instructions, including:

• Setting desired water temperature.
• Understanding display codes and indicators.
• Initiating heating cycles.
• Adjusting operational modes (e.g., pool/spa).

The control board processes inputs from sensors and user commands to manage the ignition sequence, gas valve operation, and fan motor, ensuring efficient and safe heating.

Maintenance

The integrated control board itself requires minimal direct maintenance. However, ensuring the overall health of your heater system will prolong the life of the control board and other components.

• Keep Area Clean: Ensure the heater's enclosure is free from dust, debris, and moisture.
• Inspect Wiring: Periodically inspect all wiring connections to the control board for signs of corrosion, looseness, or damage.
• Environmental Protection: Protect the heater from extreme weather conditions and ensure proper ventilation as specified by the heater manufacturer.
• Professional Inspection: It is recommended to have a qualified service professional inspect your heater system annually, which includes checking the control board and its connections.

Troubleshooting

If your heater is experiencing issues after control board replacement, consider the following common troubleshooting steps:

• No Power:
  • Check the main circuit breaker for the heater.
  • Verify all 120 VAC and 24 VAC connections to the control board are secure.
• Error Codes (e.g., "CE" - Communication Error, "PF" - Pressure/Flow Error):
  • Refer to your heater's specific manual for a complete list of error codes and their meanings.
  • For "CE" errors, ensure the display board connections are secure. Sometimes, replacing the main control board resolves this, even if the display board was initially suspected.
  • For "PF" errors, check water flow, pressure switch connections, and ensure the pump is operating correctly.
• Heater Not Igniting:
  • Verify the ignitor connection to the control board.
  • Ensure gas supply is open and sufficient.
  • Check for proper operation of the induced draft motor (INDUCER connection).
• Intermittent Operation:
  • Inspect all wiring for loose connections or corrosion.
  • Ensure proper ventilation around the heater.

If troubleshooting steps do not resolve the issue, contact a qualified service professional for further diagnosis and repair.
