Honeywell Gas boiler control unit S4563C1027U

This Honeywell control box is a gas boiler control unit for automatic ignition systems. It includes integrated protection functions and is designed to control ignition and supervise the flame. The unit has a connector on its top for direct mounting onto a compatible gas regulator. It complies with the EN 60730-1 safety standard.

When choosing a replacement control box for this type of system, match the ignition mode (direct spark or pilot burner) and the gas regulator series. The mounting arrangement must be compatible: units designed with the connector on top are installed on top of the gas regulator, and the regulator can be orientated within 90° from the vertical actuator position. Before ordering, verify the gas regulator model and the connector pattern.
