The actuator is an extremely strong chain actuator especially developed for large and heavy roof openings and windows in the facades. An elegant alternative to traditional spindle actuators. For comfort ventilation. For smoke ventilation when the actuator opens the window completely within 60sec. (opening time) – approved according to EN 12101-2 with selected profiles. To be used together with +24V control units or control units with MotorLink®. Can be used together with espagnolette WMB. Synchronization of up to 4 window actuators – no need for an external synchronization module. Genuine position feedback and 3 speeds when using control unit with MotorLink®. Soft close function. The electronics in this actuator can be programmed to suit specific requirements – i.e. pressure- and traction force, stroke, speed/sound level – with the WAT 100 programming box, this is also possible following installation. Built-in electronic load switch-off/end stop. Electronic actuator with micro controller. The actuator has an integrated reverse function to ensure a prolonged life span of the window gaskets. Easy mounting.
