Frequently Asked Questions - Aura Smart LTM-A401S-WUS Levoit

Do I need a C wire for installation?

The Levoit Aura Smart thermostat can work with or without a C wire. If you have a C wire, follow the installation guide for systems with a C wire. If not, use the included Power Extender Kit (PEK) to create a power circuit.

How do I install the thermostat without a C wire?

Install the Power Extender Kit (PEK) at your HVAC control board. Connect the thermostat wires to the PEK as shown in the manual. Then connect the PEK wires to the control board terminals. Finally, wire the thermostat backplate accordingly.

Can I control the thermostat remotely?

Yes, download the VeSync app and connect your thermostat. You can adjust temperature, set schedules, and view usage from anywhere via Wi-Fi.

What is the O/B reversing valve setting?

If you have a heat pump, the thermostat will prompt you to select how the O/B reversing valve is engaged. Usually, it engages on cool. This setting can be changed later in the thermostat's settings.

How do I set up a schedule?

Go to the Schedule screen via the Menu. You can customize or delete default routines (Home, Away, Sleep). Swipe left to delete. You can have up to 24 routines per day.

What are room sensors and how do they work?

Room sensors (sold separately) pair via Zigbee and allow you to prioritize specific rooms or eliminate hot/cold spots. They can be assigned to different routines. Pair them through the VeSync app.

My thermostat display won't turn on after installation. What should I do?

Check that all wires are securely inserted. Ensure the HVAC cover is closed. For single R wire, connect to Rc terminal. If using PEK, verify wiring. Use a multimeter to check for AC 18–30V between C and Rc. Contact support if needed.

How do I reset the thermostat?

Remove the thermostat from the backplate and reattach it to restart. To factory reset, go to Settings > Reset (password may be required). You can also unlock via the VeSync app if you forget the password.

What is the warranty period?

The Levoit Aura Smart thermostat comes with a 2-year limited consumer warranty from the date of original purchase against defects in material and workmanship.

Troubleshooting

Problem Possible Solution
The thermostat display does not turn on.	Gently tug on each wire connected to the terminals on the backplate to make sure they are properly inserted and secure.
	Make sure the cover of your HVAC system is completely closed. Some HVAC systems do not turn on if the cover is not closed.
	If you only have one R wire (R wires include R, Rc, and Rh), make sure the R wire is connected to the Rc terminal (see About R Wires, page 18).
	If you are using the PEK, make sure the wires are connected to the correct terminals on the backplate (see step 9 of Installing Thermostat without a C Wire, page 32).
	Use a multimeter to check the voltage of the C wire and Rc wire to make sure it is AC 18–30V. The thermostat does not work with high voltage systems. Contact Customer Support (see page 73).
The thermostat freezes or crashes.	Remove the thermostat from the backplate, then reattach it. This will restart the thermostat.
Forgot lock screen password. Unlock the thermostat through the VeSync app.
Heating and cooling functions are reversed.	If you have a heat pump system, change the O/B reversing valve setting in the thermostat's settings (see Settings, page 56).
	Make sure that the W wire and Y wire are connected to the correct terminals on the backplate.
	If you are using the PEK, make sure the wires are connected to the correct terminals on the HVAC control board and backplate (see Installing Thermostat without a C Wire, page 22).
The thermostat does not show weather information.	Make sure the thermostat is connected to the VeSync app.
	In the VeSync app, make sure you input your home location and set the region to the United States.
Room sensor (sold separately) does not connect to the thermostat.	Make sure the thermostat and room sensor are added to the same VeSync account.
	One of the room sensor's batteries may be low.Replace with 2 AAA batteries.

If your problem is not listed, please contact Customer Support (see page 73).

VeSync App Troubleshooting

My smart thermostat isn't connecting to the VeSync app.

• Make sure your phone has Bluetooth ^® turned on and is not currently connected to another Bluetooth device.
- During the setup process, you must be on a secure 2.4GHz Wi-Fi® network. Confirm that the network is working correctly.
• Make sure the Wi-Fi password you entered is correct.

• There should be no spaces at the beginning or end of the password.
• Test the password by connecting a different electronic device to the router.
- If you're manually typing in the SSID and password, double check that both are entered correctly.

• Your phone should be as close as possible to your thermostat.
• Your router may need to be at a higher location, away from obstructions.
• Make sure your thermostat and router are away from appliances (such as microwave ovens, refrigerators, electronic devices, etc.) to avoid signal interference.
• If you're using a VPN, make sure it's turned off while setting up your thermostat.
• Disable portal authentication for your Wi-Fi network. If portal authentication is enabled, the thermostat will not be able to access your Wi-Fi network, and setup will fail.

Note: Portal authentication means that you need to sign in to your Wi-Fi network through a web page before you can use the Internet.

VESYNC APP TROUBLESHOOTING (CONT.)

My thermostat is offline.

• Make sure your router is connected to the internet and your phone's network connection is working.
- Delete your offline thermostat from the VeSync app. Swipe left (iOS®) or press and hold (Android"), then tap Delete Reconfigure the thermostat with the VeSync app.

Note: Power outages, internet outages, or changing Wi-Fi routers may cause the thermostat to go offline.

If your problem is not listed, please contact Customer Support (see page 73).
