The Joint Control and Ignition System (CVI) is an innovative solution designed to optimize the operation of gas boilers, heaters and water heaters equipped with an automatic ignition system. The basis of CVI are advanced ignition regulators Resideo S4565A2035U, working in cooperation with gas regulators from the VK41 series …, which provides a high degree of reliability and safety in critical situations.

The Honeywell S4565A 2035U ignition regulator performs several key functions:

1. Safe Ignition: CVI guarantees safe ignition and effective flame control on the main burner of the heating equipment. This significantly reduces the risk of fire and emergency situations.

2. Flexible Settings: The system allows you to configure the ignition process, as well as monitor the flame and regulate the gas flow for both the main and pilot burners, ensuring optimal efficiency and stability of the equipment.

The S4565 A 2035U series includes a variety of variations designed for different ignition systems:

– Spark Ignition Of The Burner (DBI): These regulator options provide a safe ignition time, which is especially important for systems with spark ignition of the burner.

– Pilot Burner Ignition (IP): For systems with pilot burner ignition, regulators with the suffix A denote an atmospheric system with spark ignition of the burner.

These Honeywell S4565A2035B ignition regulators with a voltage of 220/240 V~ can be directly connected to the electrical circuit of the VK41 series gas regulator…, but it is important to note that they do not affect the flame directly. They provide outstanding performance and reliability, and are available in various modifications corresponding to different ignition systems.

The Honeywell S4565A2035 control unit is also suitable for DE DIETRICH DTG 111 NEZ and Dakon DAKON GL ECO boilers: 71510418.

General provisions

The general provisions of the burner control system include the following aspects:

1. All burner control protection functions are integrated into a reliable system. This ensures comprehensive safety and operational efficiency.

2. The system pays special attention to the development of optimal solutions for systems with spark ignition of the burner (DBI) and systems with pilot burner (IP) for ignition of the main burner. This ensures the accuracy and reliability of the ignition process.

3. The gas regulator and ignition regulator are created using time-tested principles. This guarantees the reliability and stability of the system.

4. The installation of the ignition regulator on the gas regulator is simplified due to the presence of a connector provided on the top of the regulator. This makes the installation process more convenient and faster.

5. The controller can be installed within an angle of 90° in any direction from the vertical position of the two-position electric actuator. This provides flexibility when configuring the system depending on the specific requirements and limitations of the installation.

Reset the lock

The Honeywell S4565A 2035B ignition regulators can be reset by pressing their own or external reset button. If the first attempt fails, you should wait at least 15 seconds before trying again.


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.
