Characteristic curve

WS 160 Flat KBZET - Characteristic curve

The figures shown indicate the preset 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 - 160 m³/h

NV = 40 m³/h - 160 m³/h

IV = 40 m³/h - 160 m³/h

Essential condition: RV < NV < IV !

short description

Centralised, highly-efficient ventilation units with EC fans and constant volumetric flow regulation, including preheating register, bypass, zone shutter and enthalpy cross-counterflow exchanger, 2 supply air connections (left and right) and 1 exhaust air connection (centre), air volume 40 - 160 m³/h, connection diameter 4 x DN 125, 4 SVR 125 plug connectors or 90° B90-125 elbow needed to connect folded spiral-seams ducts (order as accessories), the DN160 folded spiral-seam duct can also be placed directly on the EPP connection, including RLS 1 WR control unit, including integrated web server and MAICO app (air@home) for mobile unit control, live reports via web tool, DIBT approval and passive house certificate, KNX and EnOcean connection possible

Product description

Comfort bypass zones model

  • Central unit with enthalpy heat exchanger, integrated bypass, preheating register and motorized zone shutter. In this way, the room air is optimally cooled at high outside temperatures and comfortably pre-warmed at low outside temperatures. Furthermore, the zone shutter allows the supply air rooms to be divided into two zones.
  • The use of the motorised zone shutter and needs-based zone regulation allows the supply air rooms to be split into 2 zones. The relevant splitting of the volumetric flows over the 2 zones can be stored in the time programme or regulated by corresponding air quality sensors in the zones.

Brief description

  • Intelligent ventilation unit with heat and humidity recovery for controlled ventilation and air extraction with an air volume of 40 to 160 m³/h.
  • Two supply air sockets (left and right) and one exhaust air socket (centre) allow the supply air lines to be routed without crossing.
  • 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. Hygiene certificate according to VDI 6022, sheet 1 available.
  • 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.
  • Mounting options: ceiling mounted or in a sloped roof.
  • 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, air valve settings). This also results in easier commissioning/air volume measurement at the valves. The volumetric flows do not require any adjustment.
  • Very quiet unit with extremely low installation height (23 cm): This makes it particularly suitable for installation in suspended ceilings. In addition, also suitable for installation in a sloped roof.
  • Various operating modes: Off, Manual, Auto Sensor, ECO exhaust air, ECO supply air.
  • RLS 1 WR room air control included in the scope of delivery.
  • ISO Coarse 80 % (G4) filter in the exhaust air and ISO ePM1 55 % (F7) pollen filter in the outside air. A filter cascade (ISO Coarse 80 % / ISO ePM1 55 %) in the outside air is possible to increase the filter service life.
  • The ventilation unit is equipped with a state-of-the-art enthalpy heat exchanger with hygiene certificate according to VDI 6022, sheet 1.
  • The WS 160 Flat 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.
  • 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.

Heat exchanger/heat recovery

  • Highly efficient enthalpy cross-counterflow heat exchanger.
  • Heat recovery up to 84 % and humidity recovery up to 53 %.
  • Hygiene certificate (no bacteria, virus growth/virus transfer) according to VDI 6022, sheet 1.
  • Heat exchanger can be cleaned with water, antimicrobial.
  • No condensation connection required.

Bypass

  • The integrated bypass shutter (100 % bypass) with needs-based bypass control makes a continuously variable bypass control possible.
  • Depending on temperature differences and user settings the room air can be cooled in an optimum manner without draughts.

Frost protection

  • The performance-controlled electrical preheating register is regulated depending on various parameters recorded in the unit.
  • The result is an efficient and energy-saving regulation strategy. Ventilation with a heat register therefore does not compromise on comfort even at low outside air temperatures.

Fans

  • Forward curved centrifugal fans in the outgoing air or outside air.
  • Energy-efficient EC direct current motors with integrated volumetric flow consistency control.
  • Possibility of pressure consistency control via the optional additional circuit board ZP 2.
  • 4 ventilation levels from 40 m³ to 160 m³, can be adjusted continuously.

Installation information

  • Easy, very time-saving installation by screwing the unit directly to the ceiling/wall.
  • Housing cover is easy to remove via screws.
