Ask a Question
  • Can it work with wind and rain detector?


    Yes, it can work with rain,wind sensor, and can work with rain sensor, smoke detecter, etc.

  • Hi, can i purchase 2 and have a wall controller operate both at the same time? I might possibly add a third later, could i also add that to the wall switch?

    Hi, one-way switch can only connect with 1 device, otherwise it will burn out.  
    If you want to hook up more than one unit, you can get multi-frequency controller, such as below, it's a 4-channel controller, can connect to 4 units in total.

    In addition, if you want to control multiple devices at the same time, you might also want to consider a smart window opener, you can group control them in the app:

  • Do these chain type openers have end stops? Do you hold the controller button until the chain stops, or does the chain stop automatically at the end of the open / close cycle. Can the controller button be pushed once to start motion, or do you have to hold the button for the full duration of the operation? Please describe controller operation with the actuator?

    If you want to open or close the window, just press the button, no need hold the button all the time, just press once. 
    The window opener will stop automatically at the end of the open / close cycle. If you want to stop the opener at a certain position, you can press the stop key.
    This device is equipped with push button/receiver and remote control, the button is hardwired, need to wiring with window opener; the remote control is wireless, it need pair with receiver, and then can control the window remotely within 10m.
