ZFR1800 Series Wireless Field Bus System Technical Bulletin 11
WRZ Series Sensors
Depending on the sensor model, the WRZ Series Sensors transmit temperature,
setpoint, humidity, occupancy status, and low battery conditions to an associated
field controller by means of a ZFR1811 Router. If the field controller is mapped to
the NxE, the data sent by the wireless sensor can be displayed.
Some applications that support the temperature or humidity control functions do
not support the occupancy/temperature setback function. Refer to a field
controller’s commissioning and operation literature to determine if the application
supports occupancy or temperature setback functions.
Note: Configure the Analog Inputs (AIs) on all WRZ Sensors as SA Bus devices
(the same as with hard-wired NS Series Sensors).
Note: The WRZ Series Sensors are designed for indoor, intra-building
applications only.
The WRZ Series Sensors require two 1.5 VDC AA alkaline batteries. The WRZ
sensors minimize power consumption by transmitting data only once per minute,
which yields an expected battery life of approximately 4 to 5 years.
ZFR Checkout Tool (ZCT)
The ZFR Checkout Tool is an optional tool, included with the installation of the
Controller Configuration Tool (CCT), that allows you to validate the wireless
connectivity and health of wireless devices within a ZFR1800 Series Wireless
Field Bus system, helping ensure a reliable mesh network is in place. You can use
the information provided by the ZCT to analyze and troubleshoot the wireless
mesh network created by a ZFR1800 Series System.
The ZCT gathers information by discovering the wireless field controllers and
wireless sensors on your network and analyzing their status and wireless
communication paths. The ZCT provides a simple report of wireless network
performance, including online status verification and wireless signal strength
information. The ZCT also provides wireless device lists, signal strength
information, and diagnostic measurements of the wireless mesh network.
Refer to the Using the ZFR Checkout Tool (ZCT) chapter of the Controller Tool
Help (LIT-12011147) for more information on the ZCT.
The ZCT requires a Universal Serial Bus (USB) adapter with ZigBee driver. For
information on this adapter and how to order it, see WRZ-SST-120 Wireless
Sensing System Tool.
Note: You must connect the adapter to the computer running CCT/ZCT before
attempting to scan the network.
