Hello,
Context: we moved into a property a few years ago and inherited a Nest Thermostat system. Was working fine until the sensor went on the thermostat. I got a second hand thermo from eBay which I rest and inputted all relevant info. The unit even downloaded and installed an update (yesterday). However, it just refuses to connect to the Heat Link which is in the same location it always has been, without any connection issues or dropouts (with the old thermostat).
I cannot get the Heat Link to display a blue flashing light, seemingly whatever combination of button presses/duration makes no difference. The only colours I get are Amber & Green.
Any help appreciated!
