Wireless Standard Sensor WS2-T-C-902 Carrier Wireless Sensor Air Conditioner Sensor


As part of Carrier’s wireless sensing line, wireless standard sensors are used to measure temperature & humidity in a space. Because there are no wires to run, they can be added to your building easily.

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 80’ away from wireless adapter
  • Enables wireless sensing on new or retrofit projects
  • Wireless software included for quick and easy sensor pairing
  • Available sensing options include:
    • Temperature only (WS2-T-C-902)
    • Temperature and humidity (WS2-TH-C-902)
    • Temperature through remote sensor (WS2-R-C-902). Remote sensor is sold separately.
  • 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
  • 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
Power supply Solar harvesting, internal energy storage
Supplemental battery A 1/2 AA 3.6 V 1200 mA battery is included to supplement power during commissioning and for low-light conditions
Maximum operating life Up to 5 days with no light power or battery
Time to fully charge Depends on available lux. Full charge in 8 hours @ 1000 lux or 24 hours @333 lux
Temperature sensor measuring range 32° to 104°F (0° to 40°C)
Remote temperature sensor input 10k Thermistor Type II (Purchased separately)
Humidity sensor 11% to 89%, ±3% RH typical
Motion sensor Panasonic AMN42122 - Effective detection range: 16.4 ft. (5 m) maximum
Protocol Customized version of EnOcean®
Radio frequency 902 MHz (North America)
Transmission range Typically, 75-80ft. (18.29 m) maximum from wireless adapter, assuming sensor and wireless adapter are separated by no more than 1 drop ceiling or 2 walls (drywall with metal studs
Transmission interval Configurable in SensorBuilder. The sensor transmits:
• On change of sensed value, and
• At a regular interval (heartbeat). The default is every 15 minutes
Change of value threshold Configurable in SensorBuilder. The temperature must change by at least .288°F (.156°C) (the default) for the sensor to send a change of value
Minimum illumination strength 150 lux, constant
