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
  • Integrated control of a solar system [in case of contemporary control of a solar system and a zone by the wallmounted control panel, it is necessary to install a programmable clip in/external module THINK.]
  • Complete soundproofing of the generator
  • Full modulating circulating pump
  • Frontal access for advanced diagnostics
