Not Heating or Cooling problem solution

Follow these steps to solve this problem.

Step 1: Press and hold the left button on the panel for 6-10 seconds.

Step 2: By following the last step, the settings menu will display on your screen. Now you show tap on the option called user.

Step 3: Now use the up and down buttons to highlight the option called Testing and then tap on it. 

Step 4: Now use the up and down buttons to highlight the problem that you’re having. If you’re not getting enough heat, highlight the heat option, and do vice versa for cooling.

Step 5: Press the button on the right to select start.

Step 6: After you’ve selected the start option, here is what will happen. The Vivint thermostat will run a test to make sure the wires are active and the temperature is changing.

When the test is completed, it means the Vivint system has made sure that things are working the way you’ve set them to. But, don’t just rely on the panel, see for yourself if things are working the way you would like them to be.

When you’ve made sure that heating/cooling is working just fine, click the done button.

Step 7: If your thermostat is providing heating/cooling, then everything is just fine, if that’s not the case, then there is a good chance that something is wrong with your HVAC system, therefore you should contact Vivint customer support.

Now we’re going to talk about the next cause. Vivint’s thermostat not responding to the app.

There are a total of 3 steps that you should take. Follow them exactly as instructed.

Step 1: Pick up your phone. Open the Vivint app and log out.

Step 2: Now go to your online account and send a command as a test.

Step 3: If the account center is working, but the app is still not working, here is what you’ve got to do. Check the signal on your mobile device. Mobile commands work best if your internet connection is good.

If the internet is not working, delete and reinstall the app. Now when the internet is connected, accept the command that you had previously sent.

That’s it! If you’ve followed the above steps the right way, you’ve successfully connected the thermostat with the Vivint app.

Thermostat batteries: check all four batteries are sitting perfectly. If not, adjust their position. Also, check for corrosion. If there is corrosion in your batteries, contact the Vivint team for help.
