XBus Thermostats

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

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. If it is still not connecting, check the thermostats to make sure there is not a bad thermostat in the chain (XBus) somewhere by pulling off the faceplates one by one and see if the connection re-establishes during this process. You may also check the X1 and X2 terminals to make sure they did not get shorted out. If you are still having issues you may have a damaged controller, contact support for further troubleshooting.

This could be for either of two reasons.  If the thermostat is being used on a Fahrenheit scale, the Up and Down buttons may have accidentally been pressed at the same time, which changes the display to Celsius mode.  To correct this, press and release the Up and Down buttons simultaneously again.  Another reason could be that the temperature sensor has been bent.  Pull off the faceplate and check the thermistor to see if it is damaged or bent over.  The thermistor is a little device sticking up in the bottom right of the circuit board, it will be either blue or black.  Make sure it is not damaged and is standing up straight off the circuit board.
 

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.
