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.

Changing the mode will set the thermostat into override mode and it will continue in the altered mode for the duration of the override timer. To return to the schedule after changing the mode you can either press the resume button or allow the override timer to end.

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

It is not recommended to exceed 125ft between thermostats. For XBus systems, each CAT5 cable run can be no longer than 1,000ft total with no more than 8 thermostats on a single CAT5 cable run. It is highly recommended to use an NT-TB terminal board as a hub for your XBus thermostat cabling. Each 'drive' (X1/X2) on a network controller can support up to 2,000ft and a maximum of 16 thermostats. With each controller having two drives, up to 32 thermostats can be supported on up to 4,000ft of CAT5 cable.

The X1 and X2 terminals should be connected to the corresponding terminals on the thermostat. It is recommended to balance the number of connections to each of the four terminals on the controller. If you have an older controller with only three terminals balance the number of wires connecting to the two X1 terminals.

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. 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.

If your equipment is 2-stage, first make sure your DIP switches are set correctly to allow second stage operation. In order to bring on second stage faster than the efficient fuzzy-logic algorithm (about 15-20min after first stage, if needed):

1) set the heating or cooling setpoint at the room temperature and let the display return to normal operation.
2) move the heat or cool setpoint up or down three degrees. After normal protection time-outs have been satisfied (2 or 4 minutes depending on your configuration), the thermostat will start first stage.
3) Once first stage is running, adjust the setpoint three more degrees in the same direction. Second stage will start.

This method bypasses thermostatic control algorithm for this single heating / cooling cycle.

You can find the manual for all of our devices under the products page. Go to the desired device and look under the "Docs" tab. Note: If you have an older device that is no longer in production contact support for a copy of the manual.

Yes, however you will need to purchase an NT-PWIRE which will take your four wire system and convert it to five wires allowing you to have a common. You can purchase the NT-PWIRE at

This could be for either of two reasons. If the thermostat is being used in 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.

All of our thermostats are powered by 24VAC and they all require a common wire. If you do not have a common wire you can purchase the NT-PWIRE and it will give you a common wire. Alternatively you can purchase a 24VAC power supply and plug it into an outlet.

NetX thermostats and sensors are accurate to +/- 1º F. The accuracy of the thermistor is +/- .01%.

Yes, the NT-TEMP is required for remote sensing. NetX thermostats use an advanced remote sensor bus which has active electronics, not just a passive temperature sensor.

Press and release the up and down arrows simultaneously.
