In addition to allowing fully bi-directional communication between Hitachi Commercial & VRF systems and KNX installations, four potential-free binary inputs provide the possibility to integrate external devices, such as window contacts or presence detectors, that allows launching internal functions focused to improve energy efficiency.

FEATURES

• 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 “timeout”, “open window” or “Occupancy”. 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 unit’s internal variables, running hours counter (for filter maintenance control) and error indication.
• Up to 5 scenes can be saved and executed from KNX.
