Application

The WRS-TTx Series Wireless Room Temperature Sensors are designed to sense room/zone temperature and transmit wireless temperature control data to TE-7800 Series and WRS-RTN Series Receivers. Depending on the sensor model, the WRS-TTx Series Sensors can transmit sensed temperature, setpoint temperature, occupancy status, and low battery conditions to an associated receiver. The associated receiver passes the temperature data on to a supervisory controller or a field controller. Note: WRS-TTx0000-1 Series Sensors (CE Mark compliant models) have a reduced transmission power (10 dBm) and transmission range to comply with the requirements of select countries. The WRS-TTx Series Sensors are designed for two types of room/zone temperature sensing systems: • The One-to-One temperature sensing system provides temperature data for single-zone temperature control based on a sensor reporting to a single TE-7800 Series Receiver. The One-to-One system provides temperature data to Johnson Controls® VMA14, AS-AHU, AS-UNT, AS-VAV, DX-9100, and FXxx Series Field Controllers. Refer to the TE-7800 Series One-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT-12011097) for more information. • The Many-to-One temperature sensing system provides temperature data for multi-zone control and allows multiple WRS-TTx Series Sensors to report to a single WRS-RTN Series Receiver. Up to 60 sensors can be associated with a single receiver. The practical average due to typical application environments is 10 to 20 sensors per receiver. The WRS-RTN Series Receiver works in conjunction with a Metasys® system Network Automation Engine (NAE) or Network Control Engine (NCE) to distribute temperature data to the multiple field controllers on the Metasys network. Refer to the WRS Series Many-to-One Wireless Room Temperature Sensing System Technical Bulletin (LIT-12011095) for more information. The WRS-TTx Series Sensors use direct-sequence, spread-spectrum Radio Frequency (RF) technology and operate on the 2.4 GHz ISM band. The sensor meets the IEEE 802.15.4 standard for low power, low duty cycle RF transmitting systems. The WRS-TTx Series Sensors operate as transceivers to create a bidirectional association with the target receiver, which allows the temperature sensing system to confirm and synchronize data transmissions between the sensors and the receiver. The WRS-TTx Series Sensors are designed for indoor, intra-building applications only
