Honeywell S4965R3027 burner control

The Resideo S4965R3027U ionization control unit is designed for use in gas heaters. This Honeywell S4965R 3027U burner control unit is used in conjunction with VK41 series gas regulators and other control methods. It strictly observes precautions in the emergency protection subsystem, guarantees safe ignition and flame control of the main burner and heating system, and also provides comfortable regulation of the boiler, including temperature control, pump and 3-way valve. Thanks to this control unit, you can perform most of the standard gas boiler control functions, switching between modes with ease.

This device is also suitable for use in various equipment, including flow-through water heaters, floor boilers, combined boilers, boilers with low emission of nitrogen oxides (Low Nox) and condensing boilers.

EMC Instructions

• To ensure long-term and reliable operation of the boiler regulator, install it in a place where the temperature is moderate and the level of temperature exposure is low. Fuses should also be provided for safety.

• The ignition cable must be installed in such a way as to minimize possible interference. It is usually laid along metal pipes or screens to reduce turns. In addition, do not install the ignition cable next to other devices.

• To suppress high-frequency interference of the boiler regulator, it is necessary to install a spark ignition cable in a well-shielded compartment. Using a 1K spark plug can reduce electromagnetic radiation.

• It is important to avoid laying the flame detection cable next to other devices, as well as the switching cable of the fan running constantly.

• The high-voltage spark ignition wire must be at a safe distance of at least 10 cm from other wires.

Standards

The S4965R3027 controller is designed in accordance with modern standards, including EN 298 (2003) for automatic control systems of gas burners and EN 60730-1 and EN 60730-2-5 for automatic electrical control devices.
