Application
The WRS-RTN Series Receivers for the Many-to-One
Wireless Room Temperature Sensing Systems are
designed to receive wireless Radio Frequency (RF)
temperature data from multiple WRS-TTx Series
Wireless Room Temperature Sensors for multiple
temperature zones. Up to 60 WRS-TTx Series Sensors
can be associated with a single WRS-RTN Series
Receiver. The practical average due to typical
application environments is 10 to 20 sensors per
receiver.
Note: The WRS-RTN0000-1 Receiver (CE Mark
compliant model) has a reduced transmission power
(10 dBm) and transmission range to comply with the
requirements of select countries.
The WRS-RTN Series Receiver works in conjunction
with a Metasys® system Network Automation Engine
(NAE) or Network Control Engine (NCE) and provides
temperature data over Ethernet to the NAE or NCE.
The NAE or NCE processes the temperature data and
distributes the data to various field controllers on the
Metasys network.
The receiver uses direct-sequence, spread-spectrum
RF technology and operates on the 2.4 GHz ISM band.
The receiver meets the IEEE 802.15.4 standard for low
power, low duty cycle RF transmitting systems.
The WRS-RTN Series Receiver operates as a
transceiver to create a bidirectional association with
the sensors, which allows the temperature sensing
system to confirm and synchronize data transmissions
between the sensors and the receiver.

IMPORTANT: The WRS-RTN Series Receiver is
intended to provide an input to equipment under
normal operating conditions. Where failure or
malfunction of the receiver could lead to personal
injury or property damage to the controlled
equipment or other property, additional precautions
must be designed into the control system.
Incorporate and maintain other devices, such as
supervisory or alarm systems or safety or limit
controls, intended to warn of or protect against
failure or malfunction of the receiver.
IMPORTANT: Le WRS-RTN Series Receiver est
destiné à transmettre des données entrantes à un
équipement dans des conditions normales de
fonctionnement. Lorsqu'une défaillance ou un
dysfonctionnement du receiver risque de provoquer
des blessures ou d'endommager l'équipement
contrôlé ou un autre équipement, la conception du
système de contrôle doit intégrer des dispositifs de
protection supplémentaires. Veiller dans ce cas à
intégrer de façon permanente d'autres dispositifs,
tels que des systèmes de supervision ou d'alarme,
ou des dispositifs de sécurité ou de limitation, ayant
une fonction d'avertissement ou de protection en
cas de défaillance ou de dysfonctionnement du
receiver.
IMPORTANT: The WRS-RTN Series Receiver is
not designed or intended for use in mission-critical
or life/safety applications.
Refer to the WRS Series Many-to-One Wireless Room
Temperature Sensing System Technical Bulletin
(LIT-12011095) for information on commissioning and
configuring a WRS-RTN Series Receiver for operation
in a Many-to-One sensing system.
