Sit BIC 580 0580107 PCB (control board)

The Italian company Sit has created a new control board with a microchip specifically for bithermic boilers that have a single heat exchanger and support both forced and natural draft. In the model range of these boilers, different control boards from different manufacturers can be used, including Sit and Honeywell. It is clearly noticeable that Sit and Honeywell electronic boards are fully compatible with each other. This means that one board can be easily replaced with another without the need for additional adjustments. For clarity and a clearer representation of the electrical connection diagram, we have attached a photo with a graphic example of this diagram. It is important to note that Sit is an Italian company specializing in the development of innovative heating and boiler control systems. They have earned recognition thanks to their advanced technologies and innovative developments in this field.
