In the box
For installations in a new spot only
Compatibility
The Nest Learning Thermostat is compatible with almost all central heating systems, including:
- Combi and condensing boilers
- System and heat-only boilers
- Hydronic underfloor systems
- Air source and ground source heat pumps (heating only)
- Zoned systems (one Nest Thermostat per zone)
- Switched live systems
- Low-voltage (dry contact) systems
Before you start
Do I need to install the Nest Thermostat somewhere new?
Many existing wired thermostats are in rooms that are rarely used. The temperature they sense is warmer or cooler than homeowners feel. So if the old thermostat isn’t in a good spot, install Nest somewhere new using the included power plug and cord, or using the Stand for Nest Learning Thermostat (sold separately).
The Nest Thermostat should be:
- Installed so that it can communicate wirelessly with Heat Link (up to a maximum distance of 30m). The home’s construction and arrangement will affect the communication range
- In a room that’s used often, so Nest can read the right temperature and the homeowner can easily reach it
- On an interior wall
- Away from drafts
- 1.2 – 1.5m from the floor
- Not behind doors, bookcases or other objects
- If in a zoned system, near the radiator that it’s controlling
Replacing an existing wired thermostat
Choose this installation method if the current thermostat connects to heating cables in the wall and it doesn’t need to move to a better spot.
Installing the Nest Thermostat in a new spot
Choose this installation if there’s a wireless thermostat, no thermostat at all or a thermostat that needs to be moved to a better spot.
Replacing an existing wired thermostat
To replace an existing wired thermostat, you’ll need to:
- Install the Heat Link first
- Remove or configure the programmer
- Install the Nest Thermostat
Install Heat Link
Switch off mains power
You’ll be working with high voltage cables, so protect yourself and the thermostat by turning off the power before you start.
Understand the cables
- Find the call-for-heat circuit in the heating system.
- The circuit may run directly from the thermostat to the boiler or pass through a junction box.
- If there’s a combi boiler with no junction box, the Heat Link will be connected directly to the boiler’s control circuit.
- You may need to test each cable to understand its function.
Choose where you’ll install the Heat Link
- The Heat Link and Nest Thermostat communicate wirelessly, even if they are also connected by cables.
- Position the Heat Link such that large metal objects—like the boiler or hot water tank—don’t come between it and the thermostat.
- Metal objects can block the wireless signal.
Run power to the Heat Link
- Use a cable to connect the L (live) and N (neutral) connectors on the Heat Link to the L and N connectors on the boiler or junction box. This will power the Heat Link.
- If existing controls operate at mains voltage, you can add a jumper cable between live and common. The jumper cable should be 0.75mm2 and 55mm long (with 8mm of exposed cable at each end).
Connect the control circuit to the Heat Link
Connect the common and call-for-heat connectors on the boiler or junction box to the 2 (common) and 3 (call-for-heat) connectors on the Heat Link. These cables will control the heating system.
Connect the thermostat cables to the Heat Link
Take two cables from the cable bundle that goes to the thermostat and attach them to the T1 and T2 connectors on the Heat Link.
Install Heat Link with a zoned system
- If this home has multiple heating zones, each zone valve will need its own Nest Thermostat and Heat Link.
- First, disconnect the thermostat cables from the zone valve.
- Use a cable to connect the L (live) and N (neutral) connectors on the Heat Link to the L and N connectors on the zone valve.
- Connect the common and call-for-heat cables to the 2 (common) and 3 (call-for-heat) connectors on the Heat Link.
- If necessary, connect the 1 (satisfied) cable from the zone valve to the Heat Link.
Attach the Heat Link
Use the included screws to attach the Heat Link to a wall near the boiler or junction box, making sure to leave 30cm of space on all sides. When you’re done, put the Heat Link cover back on. Check page 11 for placement info.
Configure the programmer
If there’s a programmer that controls hot water and heating, set the heating controls to ALWAYS ON. If the programmer only controls heating, then remove it. The Heat Link will control heating in its place.
Install the base
Remove the old thermostat and attach the base. You can either attach the base directly to the wall or use the included trim plate to cover up marks or route cables that are outside the wall. The trim plate and base snap together and should be screwed to the wall as one piece.
Connect cables
Connect the existing cables to Nest’s T1 and T2 connectors. It doesn’t matter which cable goes into which connector.
Attach the display
- Press the display onto the base until it clicks into place.
- Switch on mains power and the Nest Thermostat will begin setup.
Set up the Nest Thermostat
Just turn the ring and press to select. During setup, you will:
- Choose a language
- Connect to the home’s Wi-Fi network
- Confirm that Heat Link is connected
- If the homeowner used to have a programmer, enter that schedule
- Enter the post code
- Choose an Away temperature
Create a Nest Account
- Before the homeowner can control the Nest Thermostat from their mobile, tablet, or laptop, they need a
- Nest Account. Tell them to create one at nest.com/eu/account or just download the Nest app.
- Once the thermostat is connected to Wi-Fi, the Nest app will automatically add it to a Nest Account.
- Questions about connecting to a Nest Account? Visit nest.com/eu/pairing.
Installing the Nest Thermostat in a new spot
If you’re installing the Nest Thermostat and aren’t connecting it to any cables within the wall, then you’ll need to:
- Install the Heat Link first
- Remove or configure the programmer
- Attach the Nest Thermostat to the wall
- Plug the thermostat in with the power plug and cord
