Hunter Long Range Remote Receiver Unit with SmartPort Wiring Harness. Large-scale sites such as shopping centers, industrial complexes, college campuses, and multi-unit housing complexes require high-powered remotes that can cover long distances. The Roam XL is as powerful as they come and features a simple user interface with 128 different programmable addresses. Within line of sight, it can function up to two miles from the controller. The compact, high-powered remote is a single unit that can be carried from job to job and used to remotely access any Hunter controller that has a SmartPort connector. It eliminates the need to physically visit the controller to start or stop a cycle during maintenance, installation or winterization.
