WindowMaster Special Technology
The drives are equipped with MotorLink™ technology.
They can be intelligently used with WindowMaster MotorControllers, communicating 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 suit specific needs – for example, regarding speed, noise, or pull and push 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 upon resistance during closing. The setpoint for when the drive should reverse can be individually adjusted.
Additionally, other external systems can be connected to the drive, such as motion sensors or contact strips.
