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.\u003c\/p\u003e\u003cp\u003eProgramming 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-channel self-learning fixed-code remote control\u003c\/li\u003e\n\u003cli\u003eFrequency: 433.92 MHz\u003c\/li\u003e\n\u003cli\u003eDuplicates any fixed-code remote on 433.92 MHz\u003c\/li\u003e\n\u003cli\u003eCompatible with gates, shutters, lighting, and irrigation controls\u003c\/li\u003e\n\u003cli\u003eMetallic construction with protective door over the keys\u003c\/li\u003e\n\u003cli\u003eBattery: 12 V – 27A (included)\u003c\/li\u003e\n\u003cli\u003eReprogrammable unlimited times\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOne remote replaces multiple fixed-code handsets, reducing clutter\u003c\/li\u003e\n\u003cli\u003eSelf-learning programming requires no special tools or software\u003c\/li\u003e\n\u003cli\u003eProtective key cover prevents accidental activation when carried in a pocket or bag\u003c\/li\u003e\n\u003cli\u003eMetallic build provides durability compared to standard plastic remotes\u003c\/li\u003e\n\u003cli\u003eIncluded battery means it is ready to program straight out of the box\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Unitronic 2157\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency:\u003c\/strong\u003e 433.92 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoding Type:\u003c\/strong\u003e Fixed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Channels:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgramming:\u003c\/strong\u003e Self-learning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Applications:\u003c\/strong\u003e Gates, shutters, lighting, irrigation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e 12 V – 27A (included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Metallic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (L × W × H):\u003c\/strong\u003e 14.5 × 6.5 × 3 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.100 kg\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWhy You'll Love It\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUnlimited reprogramming means the remote adapts if you change your gate or shutter system\u003c\/li\u003e\n\u003cli\u003eThe key cover keeps the buttons protected in daily carry without a separate case\u003c\/li\u003e\n\u003cli\u003eCompact dimensions fit comfortably in a hand or pocket\u003c\/li\u003e\n\u003cli\u003eA single remote for four separate installations reduces the number of handsets you carry\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Unitronic","offers":[{"title":"Default Title","offer_id":56578895708542,"sku":"211292","price":11.39,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/2250\/3550\/files\/15675167342974.webp?v=1779636131","url":"https:\/\/lynk.gr\/en-eu\/products\/unitronic-2157-remote-control-433-mhz-4ch","provider":"Lynk.gr","version":"1.0","type":"link"}
