  • One status object available for each control object.
  • Control on the A.W. unit based on the ambient temperature read from the unit itself or from the temperature read by any KNX thermostat.
  • The Hitachi A.W. can be controlled simultaneously through the remote controller of the A.W. system or through the KNX bus.
