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

WindowMaster special technology
The drives are equipped with MotorLink™ technology.
They can be used intelligently 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 to meet specific needs – for example, regarding speed, noise, or pull and thrust.
When the drive is used 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 upon resistance during closing. The setpoint for reversing can be individually adjusted.
In addition, other external systems can be connected to the drive, such as motion detectors or contact strips.
