I recently moved into a new property and the previous owner has left a Nest Thermostat 3rd Gen installed, but has not provided the heatlink.
Is it possible to buy a heatlink ONLY to pair with my thermostat?
Hi there. Thanks for reaching out. The Heat Link is sold together with the thermostat so you won't be able to only buy the Heat Link. However you might find one available at third party retailers or Nest Pros.
