How it works - Installer and M&E considerations

  • Wired M-bus solution allowing for open protocol solution with manual thermal disconnection back-up
  • SAV Systems HIU (7 Series) and Kamstrup 403 or 603 heat meter required with Smart M-bus technology pre-wired in ready for install. 
  • No additional PAYG equipment (in-home display) in the property – significantly reduces CapEx and RepEx.
