System Troubleshooting Recommendations
1. If a thermostat is not detected by the VWG, verify that the LED is blinking at least 4 times. If it is only blinking
twice, ensure that the PAN and Channel of the thermostat is the same as the VWG it must communicate
with.
2. If there are no points associated to a specific thermostat, verify the LED pattern. If the LED is blinking 4 times
then the thermostat is communicating with the gateway, but its points have not been added to the LON or
BACnet database. Launch the Configuration utility tool and add that thermostat to the network / database
using the Add/Remove thermostat button.
3. When commissioning a network, it is recommended to use channels 25 and 26. Alternate these channels
between floors.
4. If a particular thermostat refuses to join the network and cannot be seen by the VWG. Please move
momentarily closer to the VWG until it has joined the network and it is added to the database. It can then be
re-located to its original position.
