Installation step by step ENEN

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.
→ Placement guidelines on page 14.
Where should you install it?
• Place it within 30 metres 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.
Before you start
8

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.

Installing the Heat Link
1. 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.
CAUTION: High voltage wires
Fuse box Switch
or
10

2. 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), 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), 6 (normally
open/call-for-heat) as needed.
If you have an OpenTherm boiler, connect its control
circuit to the OT1 and OT2 terminals.
→ See pages 136-141 for detailed wiring diagrams.

3. 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.

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.

INSTALL HEAT LINK
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.
Go to page 15 to start.
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.com/eu for more information.
Go to page 16 to start.

Installing the thermostat

5. 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.
6. 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.
→ Continue to page 17.
Installing it on the wall
IMPORTANT: Terminate and insulate all
wires according to the regulations in your
country or region.

Installing it on the stand
7. 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.
IMPORTANT: Make sure that you install
the Heat Link before you install the
Nest Thermostat.
NOTE: The Nest Stand is sold separately
and comes with its own installation
instructions. Go to nest.com/eu/stand
for more information.
