Product Overview

The Crestron Zūm® Wireless Battery-Powered Daylight Sensor (ZUMMESH-OL-PHOTOCELL-BATT) is an open-loop photocell designed to provide superior monitoring of natural daylight levels from windows in a room. It communicates wirelessly with Zūm dimmers and load controllers to automatically adjust their dimming levels according to the amount of natural daylight in the room.[1]

In a process known as “daylight harvesting,” a single daylight sensor can control multiple dimming zones arranged in relationship to the windows, adjusting each zone to maintain a consistent lighting level throughout the room. By taking advantage of natural sunlight, daylight harvesting effectively reduces energy usage while providing a more comfortable workspace.

The ZUMMESH-OL-PHOTOCELL-BATT is battery powered and completely wireless. It operates for up to ten years or more on two AAA lithium batteries (included). Zūm Mesh wireless technology affords easy “pair and play” setup and integration as part of a complete Zūm commercial room lighting system.[2]

Please refer to the Zūm Lighting Control System Setup Guide (Doc # 7957) for additional information.

  1. Item(s) sold separately. Refer to each product’s spec sheet for more information.
  2. “Zūm Mesh” refers to the peer-to-peer wireless mesh network within a room composed of dimmers, switches, load controllers, keypads, and sensors. AC-powered Zūm Mesh devices function as routing nodes, which effectively extend the range of the wireless network within the room. The ZUMMESH-OL-PHOTOCELL-BATT and other battery-powered devices only function as leaf nodes and do not extend range. Networks 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.
