Not sure which window opener suits your project best? Selecting the right device is easier than you think. It all depends on your window type, control needs, and system compatibility. For fixed windows, curtain walls, or high and hard-to-reach windows, the ZM901E-DT offers smooth sliding and a compact design that fits seamlessly. For
side-hung windows or where fire safety integration and precise control are needed, the ZM90E-DT delivers strong thrust and wider protocol support. Both models support Zigbee, WiFi, and RF wireless protocols, with the ZM90E-DT also supporting RS-485 and dry contact systems.
