The Resideo S4965R2000B control box is designed for use in gas domestic heating installations.

The Honeywell S4965R 2000B burner control unit is used in conjunction with VK41 series gas regulators.. smooth or other type of regulation. They form both an optimized subsystem of emergency protection, which provides programmed safe ignition and flame control of the main burner of the heating system, and a subsystem of comfortable regulation of the boiler, which regulates the temperature and controls the pump and 3-way valve.

Most of the standard burner control functions can be performed by a single control unit that easily switches to gas regulation.

Possible applications

• Flow-through water heaters

• Floor boilers

• Combined boilers

• Boilers with low emission of nitrogen oxides (Low Nox)

• Condensing boilers

EMC instructions

• To ensure long-term trouble-free operation, install the boiler regulator in a place of the heating system that has a low temperature and low radiation level. The boiler regulator must be equipped with external fuses.

• The position of the ignition cable must be determined to ensure the lowest radiation. It is usually necessary to lay the ignition cable along metal pipes or shielding metal in order to minimize the loop area.

• Do not lay the ignition cable near other cables.

• To suppress RF interference, the boiler regulator containing the spark ignition device cable must be mounted in a well-shielded compartment.

• RF radiation can be reduced by using a 1K spark plug.

• Do not lay the flame detection cable near other cables.

• Do not lay the switching cable of a DC fan near other cables.

• The high-voltage spark ignition wire must be located no closer than 10 cm from other wires.

Standards

The S4965R2000 burner controller is designed in accordance with European standards:

• EN 298 (2003): Automatic control systems for gas burners.

• EN 60730-1 and EN 60730-2-5: Automatic electrical control devices for household and similar purposes.
