Maico Central Ventilation unit WS 320 BR

Bypass version:

• With bypass and counterflow plate heat exchanger.
  
• Unit in right-hand configuration.
  
• Highly efficient ventilation unit achieves energy efficiency class A+ without optional accessories.
  
• Modulating, automatic 100% bypass for passive summer night cooling with adjustable minimum supply-air temperature limit.

Short description:

• Central, compact and very quiet residential ventilation unit with heat recovery.
  
• For controlled supply and extract ventilation.
  
• Particularly suitable for modern new builds and refurbishment projects.
  
• Eligible for KfW and NRW funding schemes.
  
• Wall-mounted or floor-standing installation (optional).
  
• ISO Coarse 85% (G4) filter in the extract air and ISO ePM1 80% (F7) pollen filter in the outdoor air. A filter cascade (ISO Coarse 85%/ISO ePM1 80%) can be used in the outdoor air to extend filter service life.
  
• All units are equipped with state-of-the-art counterflow plate heat exchangers or enthalpy heat exchangers with hygiene certificates in accordance with VDI 6022, Sheet 1.
  
• Complete separation of extract-air and supply-air paths 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.
  
• All residential ventilation units can be controlled via the air@home app and the browser-based web tool (www.air-home.de) using the integrated LAN interface.
  
• Standard USB port for commissioning, control-system updates and servicing.
  
• All units are equipped with highly energy-efficient EC fans.
  
• The integrated automatic constant-airflow control permanently maintains the set airflow under all operating conditions (e.g. filter contamination, air-valve settings). This also simplifies commissioning and airflow balancing at the valves.
  
• A combined sensor (humidity/temperature) integrated as standard in the extract air enables demand-controlled ventilation as well as an intelligent frost-protection and dehumidification strategy (excess-humidity protection).
  
• All units feature a frost-protection strategy adapted to the actual demand.
  
• All units also have a multifunction contact for controlling, for example, a brine ground heat exchanger (uncontrolled pump), operating and fault indication, preheating or reheating coil, external dampers or cooling.
  2 input contacts (12 V and 230 V) are available, e.g. for safety-related shutdowns.
  
• Various inputs/outputs enable 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.
  
• 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 for additional functions such as constant-pressure control of EC fans, zone damper, brine ground heat exchanger (controlled pump) and filter differential-pressure measurement.
  Maximum unit flexibility thanks to a wide range of equipment and connection options.
  
• Modern modular unit technology enables easy retrofitting (e.g. preheater, bypass) and high user-friendliness for service and maintenance.
