need a fifth wire for a common wire. Use the K terminal in place of the Y and G terminals on conventional or heat pump systems to
provide control of the fan and the compressor through a single wire—the unused wire then becomes your common wire. See THP9045

Checking signal strength
After you successfully connect to the Wi-Fi
network (see “Connecting to Wi-Fi” step 1.5),
the thermostat will display signal strength. The
signal strength symbols have the following
meanings:
Signal strength is 75%–100%
Signal strength is 50%–75%
Signal strength is 0%–50%
You can also check signal strength at any time after the thermostat is connected to the
Wi-Fi network by pressing MENU then Wi-Fi Setup.

Unsuccessful connection
If you are unsuccessful in connecting the thermostat to the Wi-Fi network, you will
see a Connection Failed screen. Press the t button for other tips about this failed
connection. Here are three specific reasons the connection might be unsuccessful.
For all Connection Failed screens, pressing Done will return to the Menu screen.
Invalid Password
The password you entered is invalid. Check that you have the right password and try
again.
Press Done to return to “Connecting to Wi-Fi” step 1.3 on page 8.
No IP Address
The thermostat was unable to obtain an IP address from the router. Verify the router is
correctly set up to automatically assign IP addresses. This connection can take several
minutes. If there is still no connection, remove the thermostat from the wallplate for 10
seconds, then snap it back into place.
No Internet Link
The thermostat connected to the Wi-Fi network but was unable to establish a
connection to the internet. Check the router settings and try again. Make sure the
Ethernet cable is plugged into the router and try rebooting the router if necessary.
