Window Actuator for VELUX® WML 820 0102

Compact 24 V DC smoke and heat exhaust window actuator with electronic end stop for installation in VELUX roof windows GGL, GGU, and VL. The window actuator is mounted behind the ventilation flap and is therefore not visible when the window is closed.

The window actuator is also suitable for daily ventilation and can open and close against a nominal load. The housing and the chain of the window actuator are corrosion protected. The window can be opened continuously up to a maximum of 540 mm. The window actuator is equipped with a 1.5 m silicone cable.

Installation Note

The WML 820 is designed for:

• VELUX roof windows GGL, GGU from size 204 to 810
• VL from size 43 to 109

If a window actuator WMG 500, KEM 110, KEM 113, KEM 115, EBM or EB was previously installed in the window, the closing plate as well as the locks and friction springs must be reinstalled, and the ventilation flap may also need to be replaced to ensure proper functioning of the WML 820.
