BlueLink Model 7205 Thermostat

Can I connect my thermostat to a dual band router?

Yes, however you must connect to the 2.4 GHz band and not the 5 GHz band. Additionally, these two bands must have different network names and network passwords. If you are using the same name and/or password for both bands you may experience connection problems with your thermostat.

Can I connect to a hidden network (SSID)?

Yes, but you must unhide the SSID during the thermostat registration process. Once registration is complete, you can once again hide the SSID using your routers network configuration tools.

Does this thermostat require a 24VAC Common "C" wire?

Wi-Fi will work without a common "C" wire on most conventional systems. Heat pump systems and heat-only/cool-only systems do require a common "C" wire in order to operate Wi-Fi.

How do I clear my thermostat Wi-Fi connection?

1) Press and hold down the RETURN button for one second.
2) Press RETURN until you see the word WIFI in the display.
3) Press the ▲ (up) button until CL WIFI appears in the display.
4) Press RETURN to exit and clear the Wi-Fi connection.

I received a FAIL 4 code on my thermostat during Wi-Fi setup. What does that code mean?

What do I do if my Wi-Fi router does not use security (password)?

If you are using a non-secured Wi-Fi network you can still register your thermostat, however you will have to enter a [space] in the network password field and then proceed with the registration process.

What do I need to do if I change my Wi-Fi router password?
