Honeywell Combined control and ignition system S4565A2019U S4565A 2019B

This combined control and ignition system is designed for gas boilers, heaters, and water heaters with automatic ignition. It operates at 220–240 V and has IPX4 protection. The unit supports both direct burner ignition (dbi) and pilot burner ignition (ip) systems, providing spark ignition and flame monitoring. It includes a manual reset lockout with a reset wait time of 15 seconds, and can be reset via its own or an external button. The control box is compatible with Honeywell VK41 series gas regulators and can control both the main and pilot burner. It meets EN 298 and EN 60730-1 safety standards and can be installed in any orientation.

Parts of this type are selected by matching the supply voltage (commonly 220–240 V), the ignition system type (direct or pilot), and the enclosure version (new or old n). The reset button configuration (external or internal) and protection class (e.g., IPX4) must also match the installation. Such units install on the gas regulator via a connector on the top; the orientation can be set within 90° in any direction from vertical. Verify compatibility with the specific gas regulator series (such as VK41) before ordering.
