Even if you have changed the brightness level of the display screen of your Vivint smart thermostat and it is now blank or the battery is blinking low even though the batteries have not been replaced, it is time to replace them. Vivint thermostat batteries are easy to replace and this can be done without hiring the professional services of a technician. It does not take a lot of effort to fix your Vivint thermostat if it is out of power; a couple of AA batteries would suffice.

Materials Needed

  • New AA alkaline batteries, generally 4 in number are needed as they are used in most of the gadgets.
  • Phillips head #1 screwdriver
  • Before You Begin
  • It is always useful to refer to the manual of your Vivint thermostat to determine the nature of batteries required and the number needed. Most models take four AA batteries whereas others need AAA batteries. The use of the wrong batteries can be potentially dangerous for the thermostat or make it work incorrectly.
  • Buy the original alkaline batteries from a good store that you trust. Rechargeable batteries should not be used with your Vivint thermostat. They provide a lower voltage that may in turn affect the proper working of the smart thermostat.
  • Do not power off the HVAC system while replacing the batteries of the Vivint thermostat. This helps avoid triggering the system during unwanted occasions.
  • Make sure to have your Vivint account details close by. For the new batteries, you will be required to go back to the thermostat and re-connect to your Wi-Fi network.

Guidelines for Replacing Batteries on Vivint Thermostat

  1. Take your Vivint thermostat on the wall of your house. It will be located either in the hall that is a part of your house or a living space. If there are multiple thermostats for the different zones within the house make sure you are not holding the wrong one.
  2. Environmentalists should look for a small cover door that is usually fastened using a Phillips head screw at the bottom of the thermostat housing. You might have to detach the main outer casing part right from the base plate to be able to get to the battery compartment.
  3. Leverage the Phillips screwdriver to unscrew the battery compartment cover or if it has more than one screw, unscrew all the required ones. Store them in some places where you can access them later in the process of re-establishment of your computer.
  4. Pull the battery compartment door and look for the batteries in the inside compartment. It is crucial to note that current Vivint smart thermostat models use four AA batteries while checking the type and number of the model in question. The old batteries should be easily removable by hand it is for this reason that the batteries are disassembled.
  5. Place the required number of new AA alkaline batteries into the battery compartment of the mouse. If the wiring gets reversed, be careful about the positive and negative orientation indicated on the thermostat battery terminals.
  6. After new batteries are tightly fitted into the thermostat, cover the battery compartment with its cover again. In the same manner, replace any screw that you might have unscrewed earlier to assist in the holding of the structure.
  7. Activate the HVAC system at the thermostat to normal setting after the inspection and cleaning. The screen should now be illuminated instead of being blanked out to make it easier to monitor what is being displayed.
  8. Visit the Menu buttons as well as the display interface of the Vivint thermostat to re-establish connection with the Wireless network in your home. You may be required to type in your network password at some point in this process.
  9. Even if you are done with re-registration you may come across more on-screen prompts to finalize the re-registration and check the system’s functions. The thermostat could receive software updates that it needs to get in line with Vivint’s at this stage.
  10. Perform a quick test to check whether normal operations of the thermostat are possible. Tap arrows on the touch screen panel or in the connected smartphone application and change the target temperature in the home by several degrees. Wait for the lights to fade along with the sounds of the HVAC system turning on and off in response.
  11. Dispose of the old batteries in an environmentally friendly way by taking them to battery recycling centers. These days, all the related stores like the ones selling hardware, home goods, or electronics come equipped with free household battery recycling drop-off bins.

If you follow this simple battery replacement procedure, your Vivint smart home thermostat will be working again and it should only take about 10 minutes to do so. Keep track of the date of the battery change to avoid having to replace it too often. Regarding the replacement of the batteries of the Vivint thermostat, it is recommended to do it in approximately 1-2 years based on the runtime and frequency of usage.
