Honeywell S4565BF1088 gas boiler 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 the Honeywell S4565BF1088B burner control unit, 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 1088B relay includes modifications both for systems with spark ignition of the burner (DBI) and for systems with ignition of the pilot burner (IP), 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 1088B control box 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 S4565BF1088U series have excellent performance and high reliability. There are different modifications for different ignition systems.

General provisions

• All burner control protection functions are combined into one reliable and optimized system.

• Special emphasis in the design was placed on obtaining the optimal solution for a system used in gas heating installations with spark ignition of the burner (DBI), or a system with a pilot burner (IP) for ignition of the main burner.

• Both the gas regulator and the ignition regulator are designed using principles that have passed the test of time.

• Easy installation of the ignition regulator on the gas regulator using the connector provided on the regulator from above.

• It is possible to install within an angle of 90° in any direction from the vertical position of the two-position electric actuator.

Reset the lock

The Honeywell S4565BF 1088U burner control unit can be reset by pressing its 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.
