This is a very easy procedure, and there are many suggestions littered over the internet.
1. Remove your old thermostat from your App account - factory reset the display - your old thermostat is now free from your account
2. Fit your new display to the base connector ring
3. Press the button on the Heat Link for about 30 seconds until you get a blue pulsing light - do that twice
4. Make a note of the entry key on your Heat Link - 6 digit code by the left hand fixing screw or by the Heat Link cover screw
5. You are now ready to pair
6. Go to the display and follow the instructions - eventually you will get to a screen where the display will keep searching for your old display. Just let it search.
7. When the search has given up, you will have a choice what to do - choose ''Replace Heat Link''
8. Follow the instructions by entering your 6 digit entry key
9. When you have entered the key, you may find the screen could freeze - this is very common, with luck yours will work fine. Should the screen freeze, follow the instructions again, but when at the entry code go as far as ''Connect'', but do not click connect. Leave for about 2-3mins. After that time, then click connect.
For some reason and Googles cheap hardware, freezing is common problem, unless you are hard wired.
After that, just follow the instructions to the end.
