Burner Control




The electronic boards of BCS30_EC-ST burner control family are designed to manage gas appliances equipped with premix burner and Electronic Combustion System.
They integrate all the features to manage HIGH END wall hung boilers.
If some extra functionalities are required, through a communication bus the functions can be improved using other external boards to manage External User Interfaces, Additional Input / Output, etc…
The BCS30 burner controls platform is a wide range of products that share the same mechanical features and which differ for the implemented functions: in this way it is possible to create different technical products
while maintaining the same aesthetic.

The main feature of this platform is flexibility; it is in fact possible to use different combinations of keys to differentiate the aesthetics of the product. A version called “PLUS” is also available and, through an innovative system designed by Nordgas it is possibile to mount a larger LCD with freedom of key positioning.
