WL400

Ventilation Unit

The Ventilation Unit WL400 is installed in the ridge area of conservatories replacing the normal glazing. The WL400 discharges air into the outer atmosphere (exhaust mode) or circulates the air inside (circulation mode).
The WL400 communicates via radio with the building control systems WS1/WS1000 Color/Style and KNX WS1000 Style. Using an integrated temperature sensor inside the ventilation unit, the building control systems can utilize the circulation mode to gain heat or to reduce water condensation.
With the ventilation modules RF-WL, the Ventilation Unit WL400 can be automatically controlled in different levels. In addition to that, the WL400 can be manually and directly controlled via the radio remote control Remo 8, the pushbutton interface RFB2- UP or via the solar radio pushbuttons Corlo P RF.

For every order of ventilation units, please send the order form for ventilation units to Elsner Elektronik. The production of the ventilation units starts only after the data requested in the form corcerning the location of the device in the panel and, if necessary, colours is available!
For ventilation units with panel dimensions larger than standard panel and with different panel thickness, please request an individual offer. Please send the form by e-mail or fax.

Ventilation units are shipped as bulk cargo by a forwarding agency. In the case of a delivery address abroad, it is not possible to order bulky goods via the webshop. In this case, please ask by e-mail, e. g. via the watchlist.

  • Exhaust mode and circulation mode
  • Every WL400 requires an air intake opening of not less than 9,180 mm² (Comfort: 19,200 mm²)
  • Air circulation to gain heat (Automatic function of control units WS1/ WS1000): Warm air from the ridge area is distributed throughout the whole room by the ventilation unit
  • Air circulation to reduce condensation water (Automatic function of control units WS1/WS1000): Using a special calculating process, the control units recognize critical conditions of temperature and dew point and start the ventilation unit, usually even before any moisture starts settling
  • Wireless activation. Radio connection is automatically established after switching on of the mains voltage
  • Smoothly running radial fan
  • Continuously variable
  • Highly insulated and thermally decoupled housing (no cold bridges)
  • Extremely tight-closing flap with self-locking drive and load limit switch
  • Pressure-resistant mounting panel
  • Installation along with self-cleaning panes possible, due to silicon-free processing
  • Power and radio electronics arranged inside, but outside of the air flow
  • Maintenance possible entirely from inside
  • Automatic control and manual operation possible with the following control systems: WS1 Color, WS1 Style, WS1000 Color, WS1000 Style, KNX WS1000 Style (all from software version 1.811)
  • Automatic control possible with the following ventilation modules: RF-WL, RF-WL 0-10 V
  • Manual operation possible with the following radio transmitters: Remo 8 (from version 1.1), RF-B2-UP, Corlo P1 RF, Corlo P2 RF
