Advanced zone sensing with occupant interaction and indoor air quality awareness
The ZS2 Plus Zone Sensor combines modern design, flexible multi‑parameter sensing, and occupant interaction features such as setpoint adjustment and occupancy override, delivering enhanced comfort control and indoor air quality visibility for Automated Logic systems.
The ZS2 Plus Zone Sensor provides the function and flexibility you need to optimize comfort, indoor air quality, and efficiency in your facility. These sensors are designed to measure room temperature, motion, relative humidity, carbon dioxide (CO2), volatile organic compounds (VOCs), total volatile organic compounds (TVOCs), and particulate matter 2.5 micrometers and smaller (PM2.5). They are available in a variety of zone sensing combinations to address your specific control requirements and ventilation strategies.

Power consumption varies by configuration:
Temperature only / Temperature + Humidity: 8 mA
Temperature + VOC / Temp + VOC + Humidity: 60 mA
Temp + CO₂ + Humidity: 15 mA (idle) to 190 mA (CO₂ cycle)
Temp + CO₂ + TVOC + PM + Humidity (Standard & Plus): 15 mA (idle) to 150 mA
Additional power may be required depending on configuration.
115 kbps Rnet communication between sensor and controller
Maximum 15 sensors per Rnet network
Maximum 5 sensors per control program
The ZS2 Plus includes occupant interaction features such as setpoint adjustment, occupancy override, and an occupancy status indicator.
Depending on configuration, it can measure temperature, humidity, CO₂, VOC, TVOC, PM2.5, and occupancy.
Yes. Motion sensing and occupancy override support energy‑efficient occupancy‑based strategies.
No. Black is available only on the Temperature + Humidity + CO₂ + Motion + TVOC + PM configuration.
