Honeywell S4565R1048 gas boiler control unit

The combined control and ignition system (CVI) is designed for use in gas boilers, as well as in heaters and water heaters equipped with an automatic ignition system. This system uses Honeywell S4565R1048U oil burner control box, which interact with gas regulators from the VK41 series … in order to provide reliable emergency protection. This system provides safe ignition and flame control on the main burner of the heating system, and also provides the ability to configure ignition, flame monitoring and gas flow control to both the main and pilot burner.

The Resideo S4565R1048U control unit includes various modifications to ensure compatibility with different ignition systems, including systems with spark ignition of the burner (DBI) and systems with ignition of the pilot burner (IP). This guarantees a safe and efficient ignition time in various scenarios.

The suffix “R” in the name of the gorenje control unit S4565R 1048U indicates: auxiliary fan, ignition by pilot burner, timer of safe ignition time, absence of soft ignition blocking.

The Honeywell S4565 R 1048U gas control unit with a voltage of 220/240 V~ can be easily integrated into the electrical circuit of the VK41 series gas regulator… It is important to note that they do not affect the flame directly, but serve as an important link in the system of ensuring the safety and efficiency of gas heating devices. Ignition regulators of this series are characterized by reliability and good performance, and are available in various variations corresponding to different ignition methods.

Thus, the CVI system with Honeywell S4565R1048B oil burner safety control box is a reliable and safe solution for providing automatic ignition and flame control in gas heating devices.

Important Features

General provisions

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

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

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

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

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

Reset the lock

The burner control unit S4565R 1048B can be reset by interrupting the constant power supply.

When heating is required, the airflow control relay detects the absence of airflow and starts the fan. If an external liquefied gas (LPG) valve is connected, voltage will be applied to it. When the air flow control relay determines the sufficiency of the flow, then after a time equal to the sum of the self-test period (TC) and the pre-purge period (TP), the gas valve and the built-in or external ignition transformer are switched on (according to the add. order). The spark ignites the gas, and the resulting flame is detected by the flame sensor rod. The internal or external ignition is switched off. After the flame is established, a preset extended ignition time can be added. If the flame does not set within the safe ignition time (TS), the ignition regulator is blocked. If the flame goes out during normal operation, the ignition regulator repeats the starting sequence with pre-purging. If the air flow control relay does not detect the air flow during the pre-purge time (TP), the ignition regulator remains in standby mode with the fan running.

Standards

The burner controller 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.
