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 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):
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 networkhvac.com.
I am getting very low temperature readings from my thermostat but it is incorrect. What could be the cause?
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.
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.
