Hi , I recently purchased Nest thermostat E and started to pair. I end up getting TH026 (4050) error on nest app.

 

I tried to reset heat link multiple times by pressing heat link button for 20 sec. Still not able to pair.

 

Please  help as this is unusable

Do I need to wire heat link first as I am pairing before wiring ?

1. Reset the Heat Link E. 2. Press on the button that says Nest and hold it until the LED goes from green to blank (off) to pulsing blue to solid yellow. a. Once the light is solid yellow, release the button, and in a few seconds, the pairing light will slowly pulse. (This time, the light should stay on longer and not go out in 5 seconds.) b. Add the Heat Link E again. Once it's connected, the thermostat should continue the setup. 3. Enter the room name, schedule, and Eco temperature. 4. Test the thermostat. 5. Tap Finish.
