Honeywell S4965CM1050 gas boiler control unit

Designed to optimize the operation of gas domestic heating systems, the Honeywell S4965CM1050B gas burner control box cooperates with VK41… series gas regulators to create a reliable system. This system is an optimized subsystem of emergency protection, providing programmed safe ignition and flame control of the main burner of the heating system, as well as a subsystem for comfortable regulation of the boiler, controlling the temperature and operation of the pump and 3-way valve.

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

The HONEYWELL S4965CM 1050BU control unit is suitable for the DANKO 23 3KE boiler.

The model of the Honeywell S4965CM1050U boiler controller includes:

– Smooth regulation: This version of the gas regulator provides smoother and more precise control of the gas combustion process.

– Conventional combustion in the atmosphere: Guarantees reliable without the need for additional devices.

– With fan: The fan contributes to more efficient gas combustion.
