Note	We recommend operating the employed WindowMaster window drives only with original WindowMaster control units, as otherwise no warranty claims for the drives can be made.

WindowMaster Special Technology
The drives are equipped with MotorLink™ technology.
They can be intelligently used with WindowMaster MotorControllers, communicate with standard KNX or LON BUS systems. The drive can be used as a 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 post-installation to meet specific needs – for example, regarding speed, noise, or tensile and pressure force.
When the drive is applied as a MotorLink™ drive in an NV Advance™ system, the risk of pinching can be reduced, as the drive can be programmed to stop and reverse when encountering resistance during closing. The set point 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.
