VENT PRESSURE SWITCH | IDXLVPS1930

The Hayward Vent Pressure Switch (IDXLVPS1930) is a safety device used in Hayward pool heaters to monitor airflow and vent pressure. It ensures the combustion system is correctly operating and prevents the heater from running under unsafe conditions.

• Monitors Vent Pressure:
• The switch detects the air pressure in the venting system to confirm proper airflow.
• If pressure levels are incorrect (e.g., due to a blockage or fan failure), the switch prevents ignition to avoid hazards like carbon monoxide buildup.
• Ensures Safe Operation:
• If the venting system is correctly working, the switch closes the circuit, allowing the heater to operate.
• If improper pressure is detected, the switch remains open, stopping the heater from igniting.
• Prevents Overheating & Damage:
• Protect internal heater components from overheating due to poor ventilation.
• Reduces the risk of malfunctions and shutdowns caused by airflow obstructions.
