The Lux company makes many different devices that can be used to help regulate the heating and cooling of your home or business, including a line of thermostats. The Lux TX9000TS is one digital thermostat model that can help maintain a steady temperature throughout the area it is installed. If you have this product, you might occasionally experience issues in its operation. If this is the case, you can get it working properly again by following a few troubleshooting steps.
Press up on the thumb latch at the bottom of the base to separate the cover from the rest of the unit if you see a "Low Battery" indicator on the screen or if there is no power to the TX9000TS. When the cover is off, remove the batteries inside and insert two fresh AA batteries into the same compartment. Replace the cover when finished.
Press and hold the "Hardware Reset" button for several seconds until the display goes blank and then turns back on if the unit does not respond to button presses. Occasionally, the system may lock up and you will not be able to use it. Using the "Hardware Reset" button will unlock the unit and keep your programs saved.
Check the date and time on your display screen if the programs you are setting are not executing properly. If the time or date is incorrect, press the "Set Day" or "Set Time" button to begin changing the time and date. Use the "Up" and "Down" arrow keys to change the values and press the "Menu" button to save your changes.
Press the "Software Reset" button once to reset the programming of your Lux thermostat if the programs you have set up are not working properly after setting the time correctly. Pressing this button will leave the thermostat on but will set all of the programming back to factory standards. You will need to reprogram your start and end times for the system once you perform this task.
