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.
• KfW and NRW subsidies are available.
• Especially suitable for modern new buildings or redevelopments.
• Mounting options: suspended from the ceiling, installed in/on a wall or in a sloped roof.
• No pressure fluctuation sensitivity: The integrated/automatic constant volumetric flow 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 system 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 system update and service.
• Combination 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, external 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 constancy control” of the EC fans, zone shutter, 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.
