Project Description

Product benefits:

  • Digital control panel with back-lighted LCD display
  • Wide modulation ratio up to 1÷7: 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
  • Modulating circulating pump
  • Complete soundproofing of the generator
  • Frontal access for advanced diagnostics
  • Integration with solar system option
