Meet Nest Thermostat E
Nest Thermostat E is designed with proven energy-saving features*.
With its built-in stand, Nest Thermostat E can live on a side, table or desk.
The frosted display shows the temperature when someone is close to it and disappears when they
walk away.
There's nothing to program – it's all set with a Pre-Set Schedule that's easy to adjust. And your
customers can use Auto Schedule, so it learns their temperature preferences and then
automatically changes the temperature each day on what it’s learned.
It's easy to control. Just change the temperature with the Nest app or tell the Home Assistant to do
it. With Home / Away assist, it also turns itself down when your customers leave, to avoid heating
an empty home.
And as it suppos heating only (no hot water control), it's easy to install.

Nest Thermostat E exclusively uses a wireless Thread connection to Heat Link E.
This is because Nest Thermostat E comes with an integrated stand and isn’t designed to be
mounted in place of the old thermostat (as seen on the previous page.)
Instead, the Heat Link E is mounted where the old thermostat was and is connected to the
existing thermostat wires.

1.
We recommend that the customer
is with you during install as you
will need access to their mobile
device (must be Bluetooth -
enabled) to connect the Nest
Thermostat E and the Heat Link E,
their Nest app account and home
WiFi. The Nest Thermostat E can
only work if paired to the
customer's Nest account.
Tip: Ask the customer to download
the Nest app before your arrival and
have their WiFi password ready.
Installation step-by-step
2.
Before staing the installation,
please use the Nest app on the
customer’s mobile device and
follow all of the steps to pair Nest
Thermostat E and Heat Link E. We
recommend that you only sta
drilling holes in the walls once the
pairing is successful and all the
steps in the app are complete.
3.
Whenever pairing is peormed,
Bluetooth needs to be turned on
on the mobile device (it should turn
on automatically on Android, but it
needs to be turned on manually on
iOS devices). Also make sure that
the mobile devices are not
currently using any kind of power
saving features or airplane mode.
4.
Make sure to connect the mobile
device used for pairing to the
same WiFi that the Nest
Thermostat E will be connected
to. Avoid having the phone on
mobile data while pairing.
Before you sta, it is impoant you read these 10 steps to ensure a smooth installation.
5.
Make sure that the mobile device's OS is up to date and that the Nest app is running
the latest version. Resta the app/phone in case of pairing issues.

2019 | Condential and Proprietary | Do not distribute
6.
Any pairing issues should be
addressed by following the
instructions on the Nest app and
Nest Thermostat E display. If there
is an existing setup on the
Thermostat E, the Nest app will
guide to do a factory reset. On the
display double press it, and
aerwards long press until the
spinning circle shows up - only do
this when the app tells you to.
Factory reset the Heat Link E when
needed by pressing the buon once
to turn on the status light, and
aerwards long press the buon
until the solid yellow/amber light
shows up.
Installation step-by-step
7.
If there is an assisting device that
the Nest Thermostat E is trying to
connect to during pairing, make
sure that the assisting device is
awake and within range (example:
if Nest Protect, press its buon, if
Heat Link E, press it's buon, if Nest
Cam IQ, bring it closer etc). If
pairing fails, resta the assisting
device, and the new device that you
are trying to add.
8.
Heat Link E location is crucial. The
thermostat will test the connection.
Here are some of the things that
can hu (metal stu near it, big
metal or large amounts of
concrete/brick or distance between
the thermostat and Heat Link E)
Position the Heat Link E at least 30
cm away from boiler.
9.
Avoid any other sources of
inteerence in the vicinity of the
Nest devices: wireless inteerence:
microwave, wireless keyboard /
mouse, wireless speakers, baby
monitors, game console controller,
sma watch etc.
10.
Nest Thermostat E and the Heat Link E can only communicate wirelessly, so you
need to consider the distance between the two devices and possible sources of
inteerence, as described above.

2019 | Condential and Proprietary | Do not distribute
This is your comprehensive guide to seing up and installing Nest Thermostat E.
Please make sure you have read the previous 10 steps before following the below guide.
Prefer watching videos? Take a look at our Nest Thermostat E installation video.
Step 2: Briey test the heating system
Test the heating system fully with the current controls before installing the Nest Thermostat
E so that you can address any existing issues. At times, outdoor weather conditions may
prohibit testing. In those cases, inform the customer that you cannot test, and ask the
customer about the system's operation.
Step 1: Conrm system compatibility
Before opening the Nest Thermostat E packaging, conrm that the system can accept
On/O or OpenTherm thermostat (or Fil Pilote in France). Use the Compatibility Checker
to show you exactly where to connect each wire, click here.
Step 3: Help you customer set up on the Nest app ready for pairing of the Nest Thermostat E
Ask the customer if they have a Nest account.
If they do:
●Make sure that the mobile device's OS is up to date and that the app is running
the latest version. Resta the app/phone in case of pairing issues
●Proceed to the next step to add the Thermostat E and Heat Link E to their
account.
If they don’t:
●Download the ‘Nest app’ from Google Play or the Apple App Store.
●Open the app and click ‘Sign in with Google.’ Click on the Google account or
create a free account (you will see a buon to sign up for an account in the Nest
app.) Ask your customer to enter their email address and create a password.
●Create the customer’s Nest app prole - Postcode, Location (geo-location
service) etc.
Impoant note as on page 8:
The customer’s mobile device must be Bluetooth-enabled to link to the Nest
Thermostat E. Bluetooth should turn on automatically on Android, but needs to be
turned on manually on iOS devices. Also make sure that the mobile device is not
currently using any kind of power saving features or airplane mode.

circuit aer obtaining permission from your customer.
●Conrm the power is o and that the system is safe to work on.
Step 7a: Remove the old thermostat
●Before removing the old thermostat, take a picture of the wiring. It may be a valuable
reference.
●Identify and disconnect the wiring before removing the old thermostat. Use the wire
labels included in the Nest Thermostat E Guide if needed. Be sure to leave the original
thermostat with the customer.
Step 7b: Oer your customers installation nishing options
●You may need to cover up holes, old paint or marks le by the old thermostat.
●Ask your customer if they prefer to repair the wall themselves.
Step 8: Install the Heat Link E
Replacing an existing room thermostat with the Nest Thermostat E and Heat Link E is a simple
like for like replacement. There’s no need to change the existing wiring, please see the wiring
examples in this guide.
Step 9: Restore power to the system

Resta the Heat Link E
Press once and aerwards hold down the Heat Link E’s Nest buon until it’s light turns o. It should
take about eight seconds.
Release the buon and wait for your Heat Link E to resta
The status light will pulse blue then turn green when it reconnects to your thermostat. If the status
light is yellow, continue to step 2.
Move your thermostat and test the connection
Your thermostat may be too far away from the Heat Link E or there may be something inteering
with the wireless Thread connection.
Try moving your thermostat a bit closer to where your Heat Link E is installed.
Check that there isn’t anything between your Heat Link E and thermostat like a large mirror, or
refrigerator. Large objects made of metal or other dense materials can block wireless signals.
Check the wireless connection:
On your thermostat go to Seings, Equipment. Then select Continue Heat Link Test.
If the test fails, move your thermostat again and re-test. Sometimes moving your thermostat a few
centimetres can make a big dierence.
Reset the Heat Link E to defaults
Try reseing the Heat Link E and then reconnecting it to your thermostat. Factory reset the Heat
Link E by pressing the buon once to turn on the status light, and aerwards long press the buon
until the solid yellow/amber light shows up.
In some cases, you may need to enter the Heat Link E’s pairing code into your Nest thermostat. Pull
o the Heat Link E’s cover. Remove the wire cover’s screw. You’ll nd the code on the back of the
wire cover. It’s a combination of six leers and numbers.
Stop wireless inteerence from other electronics

from your thermostat. Find out more here.
Troubleshooting tips

2019 | Condential and Proprietary | Do not distribute
Nest Thermostat E expeise
Learn the basics
The small number is the
current temperature in the
home.
The large number is the
“target temperature” that
thermostat is set to.
You may also see a
message like “less than
ten minutes” that
estimates the time it will
take the home to reach the
target temperature that is
set on the thermostat.
The thermostat screen will
turn o if there hasn’t
been any activity nearby.
Just walk up to it and the
screen will turn on.
To change the
temperature, simply turn
the thermostat’s ring right
or le.
The temperature you set
will stay in eect until your
thermostat has a
scheduled temperature to
meet. See Use schedules to
learn how to do it.
Nest Thermostat E comes
with proven-energy saving
features. Here are some
steps you can tell your
customers that can help
reduce their energy use.
Look for the Nest Leaf
The Leaf will appear on the
thermostat when the set
temperature is helping
save energy.
Use Eco Temperatures
The thermostat can
automatically switch to
energy-saving Eco
Temperatures aer
everyone has le home.
But if your customer wants
to save energy even when
they’re home, they can
manually set the
temperature to Eco
Temperatures whenever
they like.
Can help save energy
When the thermostat is
showing the temperatures,
press the screen to open
the Quick View menu. Turn
the thermostat ring le or
right to the option you
want, then press again to
select it.
Here’s what each option
means:
Heat sets the thermostat
to heating mode. It will turn
on the heater to warm up
your customer’s home.
O turns your thermostat
o. It won’t turn on heating
unless it gets extremely
cold in the home.
Eco Temperatures sets
the thermostat to Eco to
help save energy.
Back returns to the
thermostat’s temperature
screen.
Seings lets you change
the temperature schedule,
Wi-Fi, network, and more.
Change the seings Use Schedules
Two temperature schedule
options are available which
can be changed on the
thermostat or Nest app.
Auto-Schedule
The thermostat learns your
customer’s temperature
preferences so they don’t
have to program it.
Simply set the thermostat
to a comfoable
temperature whenever
they want. In a few days, it
will learn a temperature
schedule and then
automatically change the
temperature each day on
what it’s learned.
To get your customers
saving energy right away,
the Nest Thermostat E
comes with a Pre-set
Schedule -
pre-programmed based on
a national average ecient
schedule that balances
energy and comfo.
How to change schedule
Your customers can either:
Adjust on the Nest app.
Or, on the Nest Thermostat
E itself. Press the
thermostat’s ring and
choose Seings, then
select Schedule.
Turn the ring and press to
pick a time to add a new
temperature or select an
existing one to change it or
delete it.
