Troubleshooting the ADC-T2000 Smart Thermostat

If this error occurs on a newly installed device, it is usually an indication that the Z-Wave device is too far from the panel to maintain a signal.

Determine if a signal extender may be your best option. Most Z-Wave devices that plug into a power outlet can be used to relay a Z-Wave signal.

You can test if this will resolve the issue by bringing panel closer to the Z-Wave Device, if it is powered by backup battery. Clear the error and see if the issue continues.

Survey the areas between the device and the rest of the network. If newly added devices have been placed near or between the network connections, there is a potential for signal interference.

To test for signal interference, remove any newly added devices or turn them off temporarily, and see if this resolves the error.

If the error occurs on a device that has been installed for more than 1 year, it may be that the batteries are too low to maintain a signal.

Below are some common troubleshooting questions and answers for the ADC-T2000 Smart Thermostat.

It is possible that an outage has caused a malfunction. Ensure you are within reach of the thermostat when attempting to troubleshoot directly or with the assistance of a in-alarm™ representative. The thermostat will also not stay visibly active if operating on batteries only; you will need to press any button to wake up the display.

A low battery on the thermostat can cause it to report an error or become unresponsive. Replace all 4 of the 1.5-Volt AA Alkaline batteries in the device to ensure proper operation, even if it is hardwire powered to the 24-Volt AC from the transformer or Heating Air Conditioner C-Wire.

If the thermostat is intended to be powered by batteries alone, program the thermostat to your panel using the learn operation while the system is being powered by batteries only. This is a best practice to maximize the battery life.
If the thermostat is intended to be powered by your HVAC system, you should remove the batteries before you program the thermostat in your panel using the learn operation, then add the batteries back after you are finished. This can help optimize Z-Wave performance.

You want to make sure the info is the same to ensure proper operation.

If you usually control it through the internet and are trying to control it directly, the thermostat may prioritize either set of directions, ignoring a conflicting input.

If so, your network may have been disrupted, requiring you to run “Rediscover the network.” This can be found on the Z-Wave tab (also known as the empower tab) . If unlisted in the app, your system may not support this option. “Rediscover network” will also need to be performed if you have deleted the Thermostat from your panel or App.

Verify if adjusting the temperature manually is interfering with the set schedules. This conflict can cause a thermostat not to respond to manual adjustments. If it does respond to manual adjustments, the set schedule could override it at a later time.

  • Distance between devices should not exceed 100′ to 125′ depending on building construction.
  • For signal range issues, you can install other Z-wave devices to act as repeaters.
  •  Some very old Z-Wave devices cannot communicate with thermostats.
  •  If you experience any trouble while programming your thermostat with your panel using the learn operation, you may need to delete the Z-Wave device and reattempt the learn operation.
  •  Once learned, wait for 2 to 4 minutes for data to transfer.
