Project Description
Product benefits:
- Removable control panel for wall-hung installation with wide text display, regulation knob,
menu selection buttons and back-lighting; supplied with the boiler - Wide modulation ratio up to 1÷10: better efficiency thanks to reduced switch-on/switch-off of
the boiler - Gas Adaptive Control (GAC) system: combustion automatic control to maintain constantly the
highest level of efficiency - Full modulating circulating pump
- High DHW performances: up to 500 l in 30 minutes (33 kW model)
- Integrated sanitary expansion vessel
- Frontal access for advanced diagnostics
