ZS2 Plus Zone Sensor
ALC’s ZS2 Zone Sensors provide the function and flexibility you need, delivering precise zoning/room control to manage conditions critical to comfort, productivity, and sustainability within your building.
The ZS2 sensors are available in a variety of zone-sensing combinations and configurations to address your application needs. These combinations and configurations include temperature, relative humidity, motion, and indoor air quality (carbon dioxide and volatile organic compounds [VOCs]).
Designed to work with Automated Logic controllers and the WebCTRL Building Automation System, the ZS2 zone sensor product line includes the ZS2 Standard, ZS2 Plus, ZS2 Pro, ZS2 Pro-F.
