Facility Explorer One-to-One Wireless Room Sensing System

Description

The Facility Explorer One-to-One Wireless Room Sensing System
enables RF room sensors to wirelessly communicate to FX-PC Series
Programmable Controllers (FX-PCA, FX-PCG, and FX-PCV). This
One-to-One Wireless Room Sensing System is the functional
equivalent of an NS Series Network Sensor, but it eliminates all the
hard wiring between the room sensor and the controller.

The two main components of this system are the FX-WRZ Series
Wireless Room Sensor and the FX-WRZ7860-0 Receiver. Depending
on the model, the FX-WRZ Series Sensor can transmit sensed
temperature, temperature setpoint, sensed humidity, occupancy
status, and low battery conditions. FX-WRZ Series Wireless Room
Sensor models are available with or without an LCD, and are designed
for indoor intra-building applications only.

Several models of FX-WRZ Series Wireless Room Sensors include an
onboard passive infrared (PIR) occupancy sensor that detects motion
to determine if a space is occupied. This feature provides up to
30% energy savings in high-energy usage environments such as
schools, dormitories, offices, and hospitals by adjusting the
temperature of the space based on the occupancy status. In addition,
the PIR occupancy sensor facilitates trending of floor space usage in
these environments.

The FX-WRZ7860-0 Receiver acts as an interface between the
FX-WRZ Series Wireless Room Sensors and the FX-PC Series
Programmable Controller. The FX-WRZ7860-0 receives the data from
the FX-WRZ Series Wireless Sensors, and passes it onto the
FX-PC Series Programmable Controller over its Sensor Actuator (SA)
Bus.

In a typical application, one FX-WRZ Series Wireless Room Sensor
reports to one FX-WRZ7860-0 Receiver; however, you can associate
up to five FX-WRZ Series Wireless Room Sensors with a single
FX-WRZ7860-0 Receiver. In these multi-sensor applications, the
receiver passes all of the room sensors’ data to the FX-PC Series
Programmable Controller. You can then configure the FX-PC Series
Programmable Controller to either average the room sensors’
temperature and humidity inputs, or select the highest or lowest
sensed temperature and humidity for control of the target zone.

Refer to the Facility Explorer One-to-One Wireless Room Sensing
System Product Bulletin (LIT-12011664) for important product
application information.
