Maico Central Ventilation unit WS 120 Trio QRV

Short description

• Intelligent ventilation unit with heat and moisture recovery for controlled supply and extract ventilation with an airflow rate of 40 to 120 m³/h.
  
• Compact and highly efficient – energy efficiency class A. Noise- and energy-optimised fans with EC technology.
  
• Eligible for KfW and NRW funding.
  
• Particularly suitable for modern new builds or refurbishments.
  
• Very quiet unit with an extremely low installation height (21 cm) and low weight (25 kg): therefore particularly suitable for installation in suspended ceilings.
• Installation on a wall or sloping roof is also possible.
  
• Outdoor-, exhaust-, supply- and extract-air spigots in DN 125: maximum flexibility thanks to 3D air spigots; duct connection possible on any side. The EPP plug simply needs to be repositioned.
  
• Additional flexibility on the supply- and extract-air side: either DN 125 connection or direct air routing with up to four DN 75 air ducts each for supply and extract air. Easy and quick installation by breaking out or repositioning the EPP plugs.
  
• ISO ePM10 ≥ 50 % (M5) filter in the extract air and ISO ePM1 ≥ 60 % (F7) pollen filter in the outdoor air.
  
• Tool-free filter replacement.
  
• The ventilation unit is equipped with a state-of-the-art enthalpy heat exchanger with hygiene certificate in accordance with VDI 6022, Sheet 1.
  
• Bypass operation / Eco mode: ECO supply air, ECO extract air for passive summer-night cooling.
  
• Complete separation of extract-air and supply-air routing throughout the unit. This prevents unwanted recirculation. Viruses (e.g. coronavirus) and bacteria are therefore not transferred.
  
• RLS 1 WR room-air control included in the scope of delivery.
  
• The WS 120 Trio can be controlled via the air@home app and the browser-based web tool (www.air-home.de) using the integrated LAN interface.
  
• Plug & Play: easy commissioning using free commissioning software and standard USB connection for commissioning, control-system updates and service.
  
• USB interface integrated into the unit cover – no need to remove the unit cover during commissioning/software updates.
  
• Insensitive to pressure fluctuations: the integrated/automatic constant-airflow control ensures that the set airflow rate is maintained continuously under all operating conditions (e.g. filter contamination, air-valve settings). This also simplifies commissioning and airflow balancing at the valves. No balancing of airflow rates is required.
  
• An integrated combination sensor (humidity/temperature) in the extract air as standard enables demand-controlled ventilation as well as an intelligent dehumidification strategy (excess-humidity protection). The unit also features a frost-protection strategy adapted to actual demand.
  
• The heat-recovery unit has a multifunction contact for controlling, for example, a brine ground heat exchanger (uncontrolled pump), operating and fault indication, preheater or reheater coil, external dampers or cooling.
  
• 2 input contacts (12 V and 230 V) are available, e.g. for safety-related shutdowns.
  
• Various inputs/outputs allow control-system connection to other building-services equipment, e.g. a heat pump.
  
• Integrated MODBUS interface (TCP/IP and RTU) for integration into the building management system.
  
• Integrated BACnet interface (TCP/IP) for integration into the building management system.
  
• The optional K-SM plug-in module enables integration into KNX building systems.
  
• The optional E-SM plug-in module enables integration into EnOcean systems.
  
• Optional ZP 1 and ZP 2 expansion boards provide additional functions such as zone damper, brine ground heat exchanger (controlled pump) and filter differential-pressure measurement.
  
• Maximum unit flexibility through a wide range of equipment and connection options.
  
• Modern modular unit technology ensures a high level of user-friendliness for service and maintenance.
