Note	We recommend operating the deployed WindowMaster window drives only with original WindowMaster control units as otherwise warranty claims for the drives cannot be granted.

WindowMaster Special Technology
The drives are equipped with MotorLink™ technology.
They can be used intelligently 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 after installation to meet specific needs – for example, regarding speed, noise, or tensile and thrust force.
When the drive is used as a MotorLink™ drive in an NV Advance™ system, the risk of entrapment can be reduced, as the drive can be programmed to stop and reverse when resistance is encountered during closing. The setpoint at which 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.
