WindowMaster special technology
The drives are equipped with MotorLink™ technology.
They can be intelligently used 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 suit specific needs, such as regarding speed, noise, or pull and thrust force.
When the drive is used as a MotorLink™ drive in an NV Advance™ system, the risk of pinching can be reduced because the drive can be programmed to stop and reverse when resistance is encountered 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.
