The combined control and ignition system (CVI) is designed for use in gas boilers, as well as in heaters and water heaters with an automatic ignition system. This system uses Honeywell S4565BF1112 ignition regulators, which work together with gas regulators from the VK41 series.. to provide reliable emergency protection. It guarantees safe ignition and flame control on the main burner of the heating system, and also allows you to program ignition, monitor the flame and regulate the gas flow to both the main and pilot burner.

The S4565BF1112 series includes modifications for systems with spark ignition of the burner (DBI) and systems with ignition of the pilot burner (IP), providing a safe ignition time.

The suffix BF indicates that this is an atmospheric system with ignition by a pilot burner and a built-in timer for safe ignition.

Honeywell S4565BF1112 ignition regulators with a voltage of 220/240 V~ can be directly connected to the electrical circuit of the VK41 series gas regulator. It is important to note that they are not intended to directly affect the flame. Ignition regulators of this series have excellent performance and high reliability, and various modifications are available for different ignition systems.

The De Dietrich 85565610 control unit is designed for installation in De Dietrich gas boilers of the DTG X..N series.
