I have a first gen. Nest thermostat controlling the heating only. I have a separate programmer for the hot water.
Is it possible to upgrade the Heatlink to enable nest to control the hot water and heating.
Thanks for reaching out. You can install a 3rd Generation Nest Learning thermostat and Heat Link. It will control both your heating and hot water.
Thanks. It’s unfortunate that you have replace everything. Apart from the cost, it’s wasteful.
Thanks for your feedback, @jdixon. If anything comes up, let me know.
