The Unitronic 2157 is a universal 4-channel remote control operating at 433.92 MHz. It replicates the function of fixed-code remote controls used with gates, roller shutters, lighting systems, and irrigation valves. You can program all four channels or only the ones you need, and reprogram them as many times as required. It is not compatible with rolling-code systems.

Programming is done through a simple self-learning procedure: hold the A and B buttons simultaneously until the LED flashes, then hold the target button on the Unitronic 2157 together with the corresponding button on the original remote until the LED flashes quickly, confirming successful code memorisation.
