BEZEL KEYPAD ASSEMBLY (SP) | IDXL2BKP1931

The Hayward Bezel Keypad Assembly (IDXL2BKP1931) is the user control interface for Hayward Universal H-Series Low NOx heaters, particularly models compliant with California emissions standards. It allows users to adjust temperature settings, monitor heater status, and troubleshoot issues.

• User Input & Temperature Control:
• The keypad buttons let you set the desired water temperature, turn the heater on/off, and navigate system settings.
• When a button is pressed, it sends a signal to the heater’s control board, triggering the corresponding action (e.g., igniting the burner, adjusting gas flow).
• Digital Display & System Feedback:
• The LCD screen provides real-time temperature readings, system status, and error messages.
• If the heater encounters an issue (e.g., low water flow, ignition failure), the display will show an error code to assist in troubleshooting.
• Communication with the Control Board:
• The keypad relays user commands to the heater’s main control board, which then adjusts the operation of burners, gas valves, sensors, and other internal components.
• This ensures efficient and safe operation of the heating system.
• Safety & Protection Features:
• The bezel casing shields the electronic components from moisture, dust, and sun exposure, helping prevent damage in outdoor conditions.
• The system prevents overheating by shutting down if unsafe temperatures or system failures are detected.
