maXsys™ is a fully featured digital electronic boiler controller. Designed for high efficiency premix residential and commercial boiler appliances.
maXsys™ combines in a single controller, safety & control electronics for premix boilers.
Together with the Honeywell VK- or VR-series of gas valves, it can drive boilers up to 900kW capacity.
With the TRIO (200-500kW) and DUO (45-250kW) heat exchangers Giannoni France is entering the fast growing commercial premix boiler market.
While the DUO is already on the market for some years the TRIO is now starting into production quantities. TRIO (as well as the DUO when used in cascade) needs special support from the controller side to handle the FLAP valve preventing the backflow of the flue gases. TRIO needs a cascading manager in the smallest configuration because it's a dual burner heat exchanger.
maXsys™ Giannoni has been designed in close cooperation with Giannoni France to cover these and also further special needs.
