The Marantec M17-891 Modular Receiver (part number 158750) is a plug-in radio receiver designed to add or restore remote-control functionality to compatible Marantec garage door and gate operators. Used as a replacement receiver or an upgrade on systems that support modular add-on receivers, it enables operation with the matching Marantec handheld transmitters, keypads, and accessories specified for the operator’s radio platform. This module is commonly applied in residential and light commercial installations where reliable wireless control is required and a clean, integrated receiver solution is preferred.
Installation typically involves connecting the modular receiver at the operator head or control board per the operator’s manual, then enrolling remotes using a simple learn procedure on the receiver. Always verify compatibility with your specific Marantec operator model and transmitter family before purchase, and follow all safety precautions: disconnect power prior to installation, keep clear of moving door components, and test safety features after programming. For best results, reference the manufacturer’s documentation for supported models, programming steps, and any wiring or mounting requirements applicable to your application.
