Removing Your Old Thermostat

• Turn off your HVAC system
• Remove your old thermostat
• Check for compatibility
• Take a photo
• Find the Thermostat Labels in the included wire tag set. Label the wires according to the corresponding terminals. [Figure 1.5]
• Carefully disconnect the wires. Each thermostat is different, but usually, you use a Philips head screwdriver to loosen a screw or press a release button to remove the wire.

Installing Thermostat with a C Wire

• Remove the old backplate
• Attach the new backplate
• Connect the wires
• Adjust the jumper (DIP switch)
• Place the thermostat
• Turn on your HVAC system

About R Wires

• If you have more than one R wire (R wires include R, Rc, and Rh):
• Connect the R or Rc wire to the Rc terminal, and connect the Rh wire to the Rh terminal.
• If you only have one R wire (R wires include R, Rc, and Rh):
• Connect the R wire—R, Rc, or Rh—to the Rc terminal.

Installing Thermostat without a C Wire
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.

Power Extender Kit (PEK)

• The PEK has 4 terminals on one side and 5 terminals on the other side.
• The side with 4 terminals is not pre-wired. Connect the thermostat wires to the terminals.
• The side with 5 terminals is pre-wired to connect to your HVAC control board.

Compatibility
The power extender kit (PEK) requires that your HVAC system has one of the following sets of wires:

• 4 Wires: W/W1, Y/Y1, G, and R (including Rc or Rh)
• 3 Wires: Y/Y1, G, and R (including Rc or Rh)

If your HVAC does not have these wires, your system may not be compatible with the PEK.

• Identify the thermostat terminals on your HVAC
• Label the thermostat wires
• Disconnect the thermostat wires
• Connect the thermostat wires to the PEK
• Connect the PEK wires to the control board
• Position the PEK
• Remove the old backplate
• Attach the new backplate
• Connect the wires
• Adjust the jumper (DIP switch)
• Place the thermostat
• Turn on your HVAC system

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.

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.
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.

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.
	One of the room sensor’s batteries may be low. Replace with 2 AAA batteries.

• 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.

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.
