C\u003c\/strong\u003e is a direct spark ignition (DSI) control board designed for use in Hayward pool and spa heaters. This board, identified by part number \u003cstrong\u003e1502802701\u003c\/strong\u003e, serves as the primary ignition control module responsible for managing the gas ignition sequence, flame sensing, and safety shutdown functions of compatible Hayward heating units.\u003c\/p\u003e\n\n\u003cp\u003eThe DSI-2 REV. C board ensures reliable and safe ignition by generating a high-voltage spark to light the burner and continuously monitoring flame presence throughout the heating cycle. If flame loss is detected, the board will automatically shut down the gas valve to prevent unsafe conditions. This revision C version reflects an updated iteration of the DSI-2 platform, potentially incorporating improved reliability or component-level enhancements over earlier revisions.\u003c\/p\u003e\n\n\u003cp\u003eThis control board is a critical replacement component for pool and spa service professionals maintaining Hayward heater systems. It is suitable for restoring proper ignition functionality in units where the original DSI control board has failed or become intermittent.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e NOVAR Controls\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e DSI-2 REV.
