The following information provides a general understanding of troubleshooting the WRG1830/ZFR183x Pro Series Wireless Field Bus:

Table 1. General network connectivity
Symptom Possible causes
The Supervisory Controller cannot discover the WEFCs. Confirm the Ethernet cable from the associated Ethernet switch is connected to the Ethernet port on the WRG Gateway.
A Network address conflict exists in which there are two WRG Gateways on the same trunk address. Verify that the Wireless Field Bus Network Address is unique and not shared by another network.
In CCT, the controller information (or device discovery dialogue) shows an incorrect MS/TP address for a controller.
  1. Locate the devices with duplicate addresses.
  2. On one of the devices, change the PAN OFFSET setting to another setting, or change the MSTP address to the correct unique value.
  3. Wait for 10 seconds.
  4. Change the PAN OFFSET setting to the former setting.
Table 2. WRG Gateway
Symptom Possible cause
The WRG Gateway cannot discover any wireless devices. The ZFR Coordinator Router is in a panel or not properly installed.
Confirm that the PAN OFFSET switches on the WRG coordinator router is set to the same value as all the WEFC routers.
Confirm that the PAN OFFSET is not a duplicate of a nearby ZFR183x network.
Verify that the ZFR1831 attached to the WRG is open for joining. Press the JOIN button on the side of the ZFR1831, or start the Join Timer from the WRG UI. The ZFR1831 LED will turn RED when joining is enabled.
If you replace the ZFR1831 attached to the WRG, you need to restore the configuration from the WRG UI.
If the WRG Coordinator router has been powered on while connected to the WRG Gateway, the router will have automatically configured itself as a coordinator router. If this router is then moved and connected to a controller, this WEFC will not be discovered by the WRG until it is reset.
The preferred method of resetting a ZFR to factory default is to press and hold the JOIN button until the LED cycles to RED, release, and then press again while the LED is blinking RED.
Browser will not display the log on screen. Some browsers such as Apple® iPhone® Safari® do not allow the standard to work. Use in address bar instead.
The network diagnostics screen shows old devices no longer on the wireless network, for example replaced units or those units recently moved to another network. Network device information may continue to show on the network diagnostics screen for up to a week after it is removed from this PAN.
Table 3. Routers/WEFC
Symptom Possible cause
The ZFR Router or the WRZ shows intermittent offline at the supervisory controller. Ensure that a wireless interference source (such as microwave oven or 2.4 GHz cordless phone) is not installed near the toggling ZFR Pro router, the WRZ, or the ZFR Pro Coordinator Radio.

Field devices installed on the trunk have duplicate MS/TP trunk addresses.

Note: An address conflict can exist between a coordinator and field controllers within the address range of 4 through 119.

Each field controller and coordinator on the FC bus must have a unique MS/TP address. Cycle power to the controller to force the controller to start communicating with its unique address.
The ZFR Router will not join the network. Ensure the PAN IDs are set correctly.
Ensure Network is open to add devices.
Ensure the Address Switch 128 is set to ON for the WEFC. ( PCA/PCG/PCX/PCV)
Table 4. WRZ sensors
Symptom Possible cause
The WRZ is not discovering its associated WEFC. The MS/TP address of WRZ Sensor does not match the MS/TP address of the WEFC.
The associated WEFC is not joined to the wireless Network.
The WRZ is not joining the wireless network. Ensure the WRZ Sensor model number is version 2, for example: WRZ-xxxxxxxx-2.
The WRZ may not have been powered on during the join network process. With WRZ powered on, and configured as required to associated WEFC, start join network time again. Discovery may take a few minutes.
The WRZ may be in Construction Mode to save battery. Press the OCCUPANCY button on the WRZ while the network is in Open for joining.
The WRZ Sensor values are unreliable. The factory calibration jumper (J5) is not installed.
Table 5. TEC31xx Thermostat Controllers
Symptom Possible cause
The TEC is not joining the wireless network. Ensure the TEC is compatible with the ZFR183x Pro Series. Model number begins with TEC31, for example: TEC31xx-xx-xxx.
Ensure that you configure the PAN ID on the TEC.
