RF-based multicontroller for precontrol of up to 2 room groups or control of ventilation plant with up to 3 stages. All inputs and outputs are also suited for universal use. The relevant data are forwarded wirelessly by the central apartment unit QAX9...

  • Suited for use in heating and cooling plants for precontrol of up to 2 room groups

  • 2 primary controllers each with a DC 0...10 V actuator

  • 1 primary controller with a DC 0...10 V actuator and 1 primary controller with a 3-position actuator

Flow and return temperature limitation, optional control of room group pumps and DHW heating

  • Suited for control of 3-stage ventilation plant incl. HR bypass, with impact from humidity, indoor air quality or CO2- level, incl. fault monitoring

  • Forwarding the heat / cooling demand signal to primary energy plant

  • RF communication based on KNX standard (868 MHz, bidirectional)
