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
