Before you start

You may want to install the Nest Thermostat somewhere new
Many wired thermostats are installed in rooms that are rarely used, so the temperature that they sense can be warmer or cooler than the temperature that homeowners feel. If the current thermostat isn’t in a good location, install the Nest Thermostat in a new place with the Nest Stand (sold separately) in a room that’s used more often.

Where should you install it?

  • Place it within 30 meters of the Heat Link. Closer is generally better. Walls and large objects between them can affect their communication range.
  • The Nest Thermostat should be in a room that’s used often so that it can read the right temperature, can sense when the home is empty, and know when to automatically turn down the heating.
  • It should have a clear view of the room.
  • Wall-mounted thermostats should be installed on an interior wall.
  • Make sure that it’s away from draughts and heat sources.
  • For zoned systems, install the thermostat in the zone that it’s controlling.

Installing the Heat Link

It’s important to install the Heat Link before the Nest Thermostat. Do not connect the thermostat directly to your heating system. High voltage current will irreparably damage the Nest Thermostat. The Heat Link is necessary, even if there are low-voltage wires.

Switch off mains power
You’ll be working with mains voltage, so protect yourself, the heating system, and the thermostat by turning off the power before you start.

Google Nest ‎A0001 Learning Thermostat 1st Gen 3

Connect to power and the control circuit
Check the heating system’s wiring to determine what type it is. Remove the Heat Link cover and connect the L (live) and N (neutral) terminals on the Heat Link to the L and N circuit on the boiler or junction box. This will power the Heat Link. Connect the heating control circuit to the Heat Link 1 (normally closed/satisfied), 2 (common), and 3 (normally open/call-for-heat) as needed.

If the system has a hot water control circuit, connect it to 4 (normally closed/satisfied), 5 (common), and 6 (normally open/call-for-heat) as needed. If you have an OpenTherm boiler, connect its control circuit to the OT1 and OT2 terminals.

Connect to the thermostat wires
Skip to the next step if you’re installing the Nest Thermostat on the stand and are using the USB cable for power. Take two wires from the wire bundle that goes to the current thermostat and attach them to the T1 and T2 terminals on the Heat Link.

Google Nest ‎A0001 Learning Thermostat 1st Gen 4

Mount the Heat Link
Use the screws included to mount the Heat Link near the boiler or junction box. Then put the Heat Link cover back on. To help ensure a good wireless connection to the thermostat:

  • Leave at least 30 cm of space on each side.
  • Install it within 30 m of the thermostat.

Google Nest ‎A0001 Learning Thermostat 1st Gen 5

On the wall
Choose this installation method if the current thermostat connects to heating wires in the wall and doesn’t need to move to a better place.

Using the stand
Choose this installation method if you’re replacing a wireless thermostat or if the thermostat needs to be moved to a better position. The Nest Stand is sold separately. Go to nest/EU for more information.

Google Nest ‎A0001 Learning Thermostat 1st Gen 6

Install the Nest base
Remove the old thermostat if there is one. You can attach the Nest base directly to the wall or use the trim plate included to cover up any marks. If you’re using the trim plate, snap it onto the base first, then screw them to the wall as one piece. When installed on the wall, the Nest Thermostat should be 1.2-1.5 m above the floor.

Google Nest ‎A0001 Learning Thermostat 1st Gen 7

Connect the wires
Connect the wires coming through the wall to Nest’s T1 and T2 terminals. It doesn’t matter which wire goes into which connector.

Google Nest ‎A0001 Learning Thermostat 1st Gen 8

Install the Nest Stand
Attach the thermostat base to the stand according to the instructions that came with it. Connect the power cable to the base and plug it into a wall socket. Stand-mounted thermostats should be placed on a table or shelf 0.75–1 m above the floor and no further than 1 m from the edge.

Google Nest ‎A0001 Learning Thermostat 1st Gen 9

NOTE
The Nest Stand is sold separately and comes with its installation instructions. Go to Nest Stand for more information.

Attach the display
Press the thermostat display onto the base until it clicks into place. Switch on mains power and the Nest Thermostat will begin setup.

Google Nest ‎A0001 Learning Thermostat 1st Gen 10

Setup
The Nest Thermostat will turn on and take you through setup. You can select a language, connect it to Wi-Fi, and tell it some things about your home and system so that it can help save energy. The Nest Thermostat doesn’t have a touch screen. Turn on the thermostat display and press it to select.

Control it with the Nest app
To control your thermostat with your mobile, download the free Nest app from Google Play or the iTunes App Store. Then create a free Nest account with the app. You can go to home nest if you’re using a computer. If you need help, please visit Nest Pairing.
