Main board MB-04 for pellet or biomass opperated appliances 230V

Our new generation main boards MB-04 and MB-04B are used to controll process of pellet or biomass opperated appliences and are a part of UniPel system. 
The UniPel system is organised in two modules - main board B-04 and MB-04B and display modules UP-04/UP-05. The connection between these two modules is made by interface cable of phone type.
