Pairing the Heat Link Wireless Connection

Pairing the heat link wirelessly to the display may have failed, even with a wired connection.

It may pair wired but will not pair wirelessly or maybe not pair at all, with or without a wired connection. Here’s what to do:

  • Find your heat link. Push and hold the button for 30 seconds until it turns pulsing blue. Time it don’t guess. Wait ten seconds then do it again. You have reset it twice. 
  • Get your heat link entry key. Found on your previous display: Settings> Technical Info> Heat Link> Entry Key (its 6 digits). With the cover removed find it on the left hand side below screw hole. Also printed on the outside of the heat link cover at the bottom.
  • On your thermostat select replace heat link. Enter the entry key.


If this fails move the thermostat closer and repeat the process. Last resort, reset the display holding it in your hand pressing and holding for one minute. Then with a wired connection to the heat link try again.
