How the Nest thermostat and Heat Link work together
With your Nest thermostat and Heat Link, you can heat your home to the temperature you want, when you want. Here’s how the two devices work together:
- Your Nest thermostat lets you set a schedule with specific times and temperatures. You can also turn your thermostat’s dial to select a new temperature any time you like.
- Your thermostat senses the ambient temperature in your home. It can also take other factors into account, such as the current weather and how long your home usually takes to heat up and cool down.
- To keep your home at the temperature you set, your thermostat will automatically turn heating on and off by sending a signal to Heat Link.
