The WindowMaster chain drive is a programmable 24V DC actuator designed for surface mounting. It is suitable for both natural smoke ventilation (NSHE) and comfort ventilation. The actuator can be controlled via ±24V control units or bus-capable motor controllers with the innovative MotorLink® technology. A special feature is the ability to synchronize up to four window actuators without the need for an external synchronization module. The chain drive provides precise digital position feedback and allows for the programming of three different speeds. Additionally, a soft close function is integrated, ensuring gentle closing of the windows. The easy installation and the ability to adjust pressure force, speed, and reversal via the WindowMaster programming device WAT 100 make this actuator a flexible solution for various applications.

• Built-in electronic load cut-off and end stop for increased safety
• Patented synchronization function for direct communication between multiple actuators
• Reversal to the ideal position of the window to extend the lifespan of the window seal
• Programming of up to three speeds in conjunction with MotorLink® controls
• Easy installation and customization options for individual requirements.
