Honeywell S4565BF1161 gas control unit

The combined control and ignition system (CVI) is designed for use in gas boilers for home central heating systems, combined boilers, as well as heaters or water heaters with an automatic ignition system. This system uses Honeywell S4565BF1161 ignition regulators, which work together with gas regulators from the VK41 series.. to create a reliable emergency protection system. This system ensures safe ignition and flame control of the main burner of the heating system. It also allows you to program ignition, control the flame and regulate the flow of gas to the main and/or pilot burner of the heating system.

The S4565BF 1161 series includes modifications for both spark burner ignition (DBI) and pilot burner ignition (IP) systems, providing a certain safe ignition time.

The suffix BF indicates that this is an atmospheric system with ignition by a pilot burner and the presence of a timer for a safe ignition time.

The Resideo S4565 BF 1161 ignition regulators with a voltage of 220/240 V~ can be directly connected to the electrical circuit of the VK41 series gas regulator. They are not intended to directly affect the flame. The ignition regulators of the S4565BF1161 series have excellent performance and high reliability. There are different modifications for different ignition systems.

The De Dietrich 85025578 control unit is installed in De Dietrich DTG 220 ECONOX/II and DTG 230 ECONOX boilers.

Reset the lock

The Honeywell S4565BF 1161 ignition regulators can be reset by pressing their own/external reset button. If the first reset failed, then wait at least 15 seconds before the second attempt.

Standards

The ignition regulator is designed in accordance with European standards:

• EN 298: Automatic control systems for gas burners.

 • EN 60730-1: Automatic electrical control devices for household and similar purposes.

With regard to electrical safety, the ignition regulator can be used in installations that meet the electrical safety requirements for household electrical appliances defined by the series of European standards EN 60335.
