Hitachi Air to Water to KNX Interface

Product code: INKNXHIT001A000
The Hitachi-KNX gateway allows fully bi-directional communication between Hitachi, Air to Water, Air Conditioner units and KNX installations.

The previous part number for this item was HI-AW-KNX-1

Price (Excluding VAT)



  • KNX certified.
  • Configured by ETS standard configuration tool.
  • Reduced dimensions allowing a quick installation inside the Air Conditioner unit.
  • Offered all the required DPT objects to be compatible with all KNX thermostats in the market.
  • Energy efficiency functions, such as ÒtimeoutÓ, Òopen windowÓ or ÒOccupancyÓ. Costs related to HVAC systems in a building are one of the highest and these functions allow to reduce them.
  • Smooth integration of KNX thermostats allowing the control of the AC unit by the own temperature sensor of the thermostat.
  • Simultaneous control of the AC unit by the IR remote controller and by KNX.
  • Total control and monitoring of the AC unit from KNX, including AC unitÕs internal variables, running hours counter (for filter maintenance control) and error indication.
  • Up to 5 scenes can be saved and executed from KNX.


  • The gateway is wired directly to an indoor unit. This allows not only the control of the main AC functions such as operating mode, fan speed, temperature setpoint, but the monitoring of errors, alarms and some internal variables.


  • The connection between the two networks is quickly set up in the ETS configuration tool using the product database available to download. Thanks to the high number of supported KNX DPTs and the KNX certification, the gateway ensures interoperability with any KNX device in the market.
