Heat Link won’t connect to thermostat. WIFI is perfect so no issue there. I’ve rebooted everything and started again, even put new lithium batteries in. Connected the thermostat to the APP with no problem. Get a code TH026 every time I try to connect the heat link to the thermostat. Reset the heat link as adevised and only get the glowing blue light for a second then it goes off. Still won’t connect. Tried to also install with Airplane made enabled, still won’t work. Help!!!
