High Protection System/bypass circuit and prevents the pump from overworking
High and Low Water Pressure Protection System
By selecting the pre-heating parameter in your combi, the waiting time for hot water usage is minimized.
Featuring brass and composite components that are resistant to thermal stresses and corrosion, ensuring a long lifespan and years of trouble-free use.
Illuminated, large information screen that allows for control of heating, hot water, pressure, and adjustments.
Operates very quietly thanks to high level of insulation
