Honeywell S4565AD2031 gas boiler control unit

The Joint control and ignition system (CVI) is designed for use in gas boilers, heaters and water heaters equipped with an automatic ignition system. This system uses Honeywell S4565AD2031U control box, which cooperate with gas regulators from the VK41… series, providing reliable protection in case of emergencies. CVI guarantees safe ignition and flame control on the main burner of the heating equipment, and also allows you to configure the ignition process, control the flame and regulate the gas flow for both the main and pilot burners.

S4565AD 2031U control unit includes various variations designed for spark ignition systems of the burner (DBI) and systems with ignition of the pilot burner (IP), ensuring a safe ignition time. The suffix AF indicates that this is an atmospheric system with spark ignition of the burner.

Gas control of Honeywell S4565 AD 2031U with a voltage of 220/240 V ~ can be directly connected to the electrical circuit of the gas regulator from the VK41 series …, however, they themselves do not directly affect the flame. These ignition regulators have outstanding performance and high reliability, and are available in various modifications corresponding to different ignition systems.

General provisions

1. All burner control protection functions are integrated into a reliable system.

2. Special attention is paid to optimal solutions for systems with spark ignition of the burner (DBI) and systems with pilot burner (IP) for ignition of the main burner.

3. The gas regulator and ignition regulator are designed using time-tested principles.

4. The installation of the ignition regulator on the gas regulator is simplified thanks to the connector provided on the top of the regulator.

5. The controller can be installed within a 90° angle in any direction from the vertical position of the two-position electric actuator.

Reset the lock

The Honeywell S4565 AD 2031B gas control unit can be reset by pressing its own or external reset button. If the first attempt fails, you should wait at least 15 seconds before trying again.

Standards

The gas burner control box 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.
