Product Overview

The ZUMLINK-DIN-DIMU is a single-channel universal phase dimmer and load controller designed to control a wide range of dimmable lighting load types. Using proprietary zero-cross filter technology, the ZUMLINK-DIN-DIMU provides superior immunity to power line noise, resulting in significant reduction of lamp flicker.

Energy-saving options, such as Zūm link presence detectors or analog photosensors (sold separately) are available to enable daylighting, occupancy or vacancy sensing, integration, and centralized monitoring and management. Room setup can be accomplished quickly through the Zūm app.

Auto-Detecting Universal Dimming

Under normal operation, the ZUMLINK-DIN-DIMU detects the connected load type and automatically selects the appropriate operating mode. Reverse phase (trailing edge) mode supports incandescent and electronic low-voltage load types, while forward phase (leading edge) mode supports LED, magnetic low-voltage, neon/cold-cathode, and 2-wire fluorescent load types. Center phase mode is also available, combining reverse and forward phase load control to address special cases. The operative mode is indicated by four LEDs on the front of the device: REV, FWD, CENTER, and AUTO.

Zūm Link Wired Technology

Zūm Link technology enables in-room lighting control through keypads and sensors wired to controllers. Zūm Wired devices connect via CBL-CAT5E-ZUMLINK-P CAT5e cable (sold separately) to RJ-45 ports to provide simple daisy-chaining and lighting control of compatible loads. The Zūm Wired devices work together in a local ecosystem to provide customized solutions using the Zūm app.

Energy Efficiency

Occupancy sensor, vacancy sensor, and daylight sensor connectivity enables significant energy savings. To reduce energy usage, lights turn off automatically when the room is vacant and dim gradually depending on the amount of natural daylight in the room.

DIN Rail Mounting

DIN rail Zūm devices snap onto a standard DIN rail for installation in a wall mount enclosure (Crestron DIN-EN series or similar) or on a wall panel.
