Characteristic curve

Trio QD-ARV - Characteristic curve

The figures shown indicate the pre-set ventilation levels (“factory settings”).

1 = 60 m³/h, reduced ventilation (RV)

2 = 90 m³/h, nominal ventilation (NV)

3 = 120 m³/h, intensive ventilation (IV)

I = Interval or “humidity protection operation” depending on RV

Individual settings available:

RV = 40 m³/h - 120 m³/h

NV = 40 m³/h - 120 m³/h

IV = 40 m³/h - 120 m³/h

Essential condition: RV < NV < IV !

Trio QD-ARV

short description

Very quiet and compact decentralised unit through which air flows crosswise, exhaust air to the right, with effective heat and humidity recovery, EC fans with constant volumetric flow regulation, connection of a small channel system, 40 – 120 m³/h, frost protection from integrated preheating register.

Product description

Crosswise flow with preheating register

  • Decentralised unit with crosswise flow with preheating register, exhaust air to the right.

Brief description

  • Intelligent ventilation unit with heat and humidity recovery for controlled ventilation and air extraction with an air volume of 40 to 120 m³/h.
  • Compact and highly efficient – energy efficiency class A. Sound and energy-optimised fans in EC technology.
  • Eligible for KfW funding: Especially suitable for modern new buildings or redevelopments.
  • Very quiet unit with extremely low installation height (22 cm): This makes it particularly suitable for installation in walls, ceilings or sloping roofs.
  • ISO ePM10 ≥ 50 % (M5) filter in exhaust air and ISO ePM1 ≥ 50 % (F7) pollen filter in outside air.
  • The ventilation unit is equipped with a state-of-the-art enthalpy heat exchanger with hygiene certificate according to VDI 6022, sheet 1.
  • Bypass mode / Eco mode: ECO supply air, ECO exhaust air for passive summer night cooling.
  • Complete separation of exhaust air/supply air ducts throughout the unit. This prevents unwanted recirculation of air. Viruses (e.g. Corona virus) and bacteria are therefore not transmitted.
  • RLS 1 WR room air control included in the scope of delivery.
  • Maximum flexibility due to flexible air socket in DN 125: Outside air and outgoing air connection on the face side (ceiling installation) or on the rear side of the unit (wall installation).
  • The trio can be controlled via the APP (air@home) and the browser-based web tool (www.air-home.de) using an integrated LAN interface.
  • Plug & Play: Easy commissioning thanks to free commissioning software and standard USB connection for commissioning, control update and service.
  • No pressure fluctuation sensitivity: The integrated/automatic volumetric flow constancy control ensures permanent compliance with the set volumetric flow under all operating conditions (e.g. filter contamination).
  • Combi sensor (humidity/temperature) integrated as standard in the exhaust air enables demand-driven ventilation operation as well as an intelligent dehumidification strategy (excess humidity protection). Furthermore, the unit is characterized by a frost protection strategy adapted to the real demand.
  • The heat recovery unit has a multifunction contact for the control of, e.g., brine earth heat exchanger (unregulated pump), operation and fault display, pre-heating or supplementary heat register, shutters or cooling.
  • Two input contacts (12 V and 230 V) are available for, e.g., safety shutdown.
  • Various inputs/outputs enable a control connection to other building service installations, e.g., the heat pump.
  • Integrated MODBUS interface (TCP/IP and RTU) enables integration in the building control system.
  • The optional K-SM plug-in module enables integration into KNX building control systems.
  • The optional E-SM plug-in module enables integration into EnOcean systems.
  • Optional additional circuit boards ZP 1 and ZP 2 for expansion functions such as “pressure consistency control” of the EC fans, zone damper, brine earth heat exchanger (regulated pump), filter differential pressure measurement.
  • Maximum unit flexibility thanks to a wide range of equipment/connection options
  • Modern unit module technology enables a high degree of user-friendliness for service and maintenance.

  • 1 combi sensor (temperature and humidity) in exhaust air socket.
  • Up to four external sensors of different types (CO2, VOC, humidity) can be connected.
  • Multifunction contact for the control of e.g. brine earth heat exchanger (unregulated pump), operation and fault indicator, preheating or supplementary heat register, shutters or cooling.
  • Inputs for safety shutdown via 12V contact or 230V contact (e.g. smoke detector, fire alarm, differential pressureless fireplace).
  • Additional pushbutton input for triggering time-limited intensive ventilation (intermittent ventilation).
  • Expandable via optional additional circuit board ZP 1 for the control of:
    • 3-way shutter (e.g. earth-air heat exchanger)
    • a regulated pump (e.g. brine earth heat exchanger)
