WindowMaster Special Technology
The drives are equipped with MotorLink™ technology.
They can intelligently communicate with WindowMaster MotorControllers and integrate 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 by WindowMaster.
The chain drive can also be programmed post-installation to meet specific needs – for example, regarding speed, noise, or tensile and compressive force.
When 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 when resistance is encountered during closing. The set point for reversing can be individually adjusted.
Additionally, other external systems can be connected to the drive, such as motion sensors or contact strips.
