Wireless sensors work in conjunction with a wireless adapter, which enables wireless communication between the sensors and an i-Vu® BACnet controller in the space. By sensing temperature, humidity and occupancy wirelessly, our i-Vu controllers can make smart decisions to optimize the control of heating, cooling, and lighting systems in the building, providing optimum occupant comfort and energy efficiency.
- Easy to install
- Communicates on the Rnet sensor network via a wireless adapter
- Can be installed up to 60’ away from wireless sensors
- Enables wireless sensing on new or retrofit projects
- Wireless software included for quick and easy sensor pairing
- Includes dial for adjusting heat/cool setpoints
- Available in two models: temperature only (WS2-TO-C-902), and temperature & relative humidity (WS2-THO-C-902)
- Wireless and battery-less space sensors (assuming sufficient lighting exists in space)
- Maintenance-free capacitors power the sensors during unlit periods for up to 5 days without a light source
- No repeaters or amplifiers required for zone-based applications
-
Integrates seamlessly with i-Vu® system alarming for proactive monitoring of important sensor conditions, including:
- Sensor charge level
- Sensor strength signal
- Sensor offline
- Can co-exist on Rnet with Carrier’s wired ZS sensors
- Single-zone controllers can support a total of 5 sensors
- Multi-zone controllers can support up to 15 sensors
