WL-Z

Air Supply Unit

The Supply air unit WL-Z is installed in the pedestal area of conservatories or glass façades replacing the normal glazing. As soon as air escapes through a roof light or is exhausted through an extraction device, cool air flows independently from outside with the vent open. The diffusor of the WL-Z serves to distribute the air evenly and without draft in the room.
The Supply air unit WL-Z communicates via radio with the control systems WS1/WS1000 Color/Style and KNX WS1000 Style. The temperature sensor integrated into the WL-Z allows for a summer and a winter setting: The supply vent remains closed if the supply air temperature is higher than the room temperature (summer) or the entering air is too cold (winter).
With the ventilation modules RF-WL, the Supply air unit WL-Zcan be automatically controlled. With the remote control Remo 8, the solar button Corlo P RF and the button interface RF-B2-UP, the WL-Z can be switched manually and directly.

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.
