Note	We recommend operating the WindowMaster window drives used only with original WindowMaster control units, otherwise no warranty claims on the drives can be granted.

WindowMaster Special Technology
The drives are equipped with MotorLink™ technology.
They can be intelligently used with WindowMaster MotorControllers and communicate with standard KNX or LON BUS systems. The drive can be used as standard ± 24 VDC or controlled as an integrated element of the NV Advance™ or NV Comfort™ solution from WindowMaster.
The chain drive can also be programmed after installation, so it meets specific needs, e.g., in terms of speed, noise, or pull and thrust force.
When the drive is used as a MotorLink™ drive in an NV Advance™ system, the risk of trapping can be reduced, as the drive can be programmed to stop and reverse upon resistance while closing. The setpoint, when the drive should reverse, can be individually adjusted.
Additionally, other external systems can be connected to the drive, such as motion detectors or contact strips.
