Make sure the tables button is active. If the button is active make sure the window isn't resized to the bottom of the screen.

Check your DNS settings to make sure they are correct. If you don't have valid DNS addresses to use, you can always use google's defaults of 8.8.8.8 for the Primary DNS and 8.8.4.4 for the Secondary DNS.

Power cycle the controller and check to make sure you are running the most current version of the Command Center software.

To do this you must have polling turned on. In the Command Center software navigate to the graphing tab on the thermostat menu. This will show you a graph of the data that is being logged for the thermostat. If you wish to export the data click the button labeled show large graph. When the larger graph pops up click the button labeled export to the left of the screen. You may then name the file and export it as a .csv.

In the event of a power outage or power surge, the thermostats may reset and go back to address 1. Check the thermostat addresses by holding the mode and fan buttons simultaneously for twelve seconds, this will show the address of the thermostat. Multiple thermostats with the same address will cause the controller not be able to communicate with them. In this case, set the thermostats back to the correct addresses. If you do not find a solution to the issue in this FAQ section, contact support.

A power surge may damage the network controller and/or the thermostats. Check the NT-IPXB controller and make sure it has information scrolling across the LCD. Try logging in to the controller via IP address in a browser and see if it is showing up. If it is showing up, make sure all the settings are correct. If all settings are correct, try doing a power cycle on the controller.
