Please read and follow all instructions and safety guidelines in this manual
Note: Levoit cannot guarantee the quality of installation, and cannot cover associated costs.
Note: If your system hos a C wire, you do not need to install the power extender kit (PEK). The thermostat will use the C wire for power.
If your system does not have a C wire, you must install the power extender kit (PEK). The PEK connects to your thermostat wires to create a circuit that provides power to your thermostat.
The PEK has 4 terminals on one side and 5 terminals on the other side.
The power extender kit (PEK) requires that your HVAC system has one of the following sets of wires:
If your HVAC does not have these wires, your system may not be compatible with the PEK.
The following are wiring diagrams for common HVAC systems. You may be able to use these for reference when installing your thermostat.
Conventional Heating/Cooling System – C Wire
Conventional Heating/Cooling System – No C Wire (Used with PEK)
Heat Pump (Air or Geothermal) with Auxiliary Heat – C Wire
Heat Pump (Air or Geothermal) with Auxiliary Heat – No C Wire (Used with PEK)
Heat Pump (Air or Geothermal) with Auxiliary Heat, Two Transformer System – C Wire

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. |
Problem | Possible Solution |
Forgot lock screen password. | Unlock the thermostat through the VeSync app. |
Remove the thermostat from the backplate, then reattach it. This will restart the thermostat. | |

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. |
Problem | Possible Solution |
Room sensor (sold separately) does not connect to the thermostat. | Make sure the thermostat and room sensor are added to the same VeSync account. |
