Product Overview

The Crestron Zūm® Wireless ZUMMESH-EXP-16A-DIMU is a single-channel universal dimmer module designed to control a wide range of dimmable lighting load types. Utilizing proprietary zero-cross filter technology, the ZUMMESH-EXP-16A-DIMU compensates for line voltage and frequency fluctuations, providing superior immunity to power line noise and a dramatic reduction in lamp flicker.

Zūm Mesh wireless technology affords easy “pair and play” integration as part of a complete Zūm commercial lighting system. Energy-saving options are available to enable daylighting, occupancy or vacancy sensing, HVAC system integration, and centralized monitoring and management.[1]

Auto-Detecting Universal Dimming
Under normal operation, the ZUMMESH-EXP-16A-DIMU detects the connected load type and selects the appropriate operating mode automatically. 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 two LEDs located on the front panel.

Energy Efficiency
Occupancy sensor, vacancy sensor, and daylight sensor connectivity drive the potential for significant energy savings.[1] Lights will turn off automatically when the room is vacant and dim gradually according the amount of natural daylight in the room. This reduces energy usage while maintaining a consistent light level for a comfortable workspace.

Pair and Play Setup
Designed with flexibility and ease-of-use in mind, the ZUMMESH-EXP-16A-DIMU is pre-programmed with “pair and play” functionality. An installer can simply install the ZUMMESH-EXP-16A-DIMU along with Zūm keypads, occupancy or vacancy sensors, and/or a daylight sensor, set up the room with a few quick button taps, and instantly control the lights in the room – no programming required! Room setup can also be accomplished using the Zūm app if the room is equipped with a Zūm Network Bridge.[1]

Zūm Mesh Wireless Technology
Ultra-reliable Zūm Mesh wireless technology provides steadfast peer-to-peer RF communications within a commercial space without the need for physical control wiring, hubs, or gateways. Employing a 2.4 GHz peer-to-peer mesh network topology, nearly every Zūm Mesh device acts as a “routing node,” relaying wireless commands directly between Zūm Mesh devices to ensure that every command reaches its intended destination without disruption.

Zūm Mesh is smart! Every Zūm Mesh device knows its purpose and just the right messages to communicate to other Zūm Mesh devices within the space. Each Zūm Mesh device that is added to the space effectively increases the range and stability of the peer-to-peer mesh network by providing multiple redundant signal paths. Each Zūm Mesh device auto-negotiates its RF channel to provide robust communication and is protected through AES 128-bit encryption. The wireless range between any two Zūm Mesh devices is typically 50 feet (15 meters).[2]

Plenum Rated NEMA Enclosure
The ZUMMESH-EXP-16A-DIMU is designed to be mounted to a vertical surface and meets the requirements of UL® 2043 for installation in an environmental air-handling space (plenum) above a suspended ceiling. Conduit knockouts are provided on the bottom and lower sides of the unit. All connections are made via screw terminals behind the front cover.

  2. “Zūm Mesh” refers to the peer-to-peer wireless mesh network within a room composed of dimmers, switches, load controllers, keypads, and sensors. “Zūm Net” refers to the wireless mesh network that connects one or more rooms with a Zūm Floor Hub, and consists of a Zūm Net Wireless Gateway and one or more Zūm Network Bridges. AC-powered Zūm Mesh or Zūm Net devices function as routing nodes, which effectively extend the range of a Zūm Mesh or Zūm Net wireless network. Battery-powered devices only function as leaf nodes and do not extend range. A Zūm Mesh network composed predominantly of battery-powered devices may require additional AC-powered devices, such as the ZUMMESH-JBOX-PSU, to serve as supplemental routing nodes to fill any gaps in coverage. Refer to the “Installation and Setup of Crestron RF Products, Best Practices” guide (Doc #6689) for additional guidelines.
