Presentation of the MARANTEC D644-868 remote control Thanks to this remote control, you will be informed of the status and direction of movement of your motorization system: its multi-colored LEDs will indicate the position of your gate or garage door. A “vacation” function is available on your remote control so you can block your transmitter for a certain time, for added security. In fact, this function will allow you to touch your remote control without controlling your automation, which can be practical if you have young children, for example. The MARANTEC D644-868 remote control has two buttons which will allow you to control two different automations, and a third button which will indicate the status of your gate: open or closed. It is designed to be fixed on a wall. But that’s not all: the MARANTEC D644-868 remote control is equipped with the bi-linked radio system, a high security system, which will allow you to benefit from safe and quality equipment. The bi-linked radio system The bi-linked radio system is a 128-bit encryption technology. It is applicable to rolling code, which is a security system operating using an algorithm. The rolling code is known to reduce hacking of motorization systems, by providing a unique and unclonable code to your receiver each time the buttons on your remote control are pressed. Copying or decrypting the code becomes impossible, and your engine is protected. Bi-linked technology is specific to MARANTEC, and all bi-linked products are manufactured in approved MARANTEC factories, thus ensuring safety and quality. How this system works This system, although it is efficient and provides you with optimal security, will not complicate the use of your remote control, quite the contrary. All you need to do is press one of the buttons on your MARANTEC D644-868 remote control to give the command to open and close your automations. In fact, the control of your automations will not change, only the security will be more optimal. This system is very safe and will allow you to easily control all your automations. With the two-way link system, your remote control can also communicate with you: the status button and LED display can tell you whether the door is open or closed with a simple press.
