The Nest Thermostat E works with most 24V
systems, including forced air, variable speed,
heat pump and radiant systems, as well as
common fuel types such as natural gas,
electricity and oil.
It can control:
• Heating and cooling: one stage of heating
and cooling, and a second stage of either
heating or cooling
• Heat pumps: with auxiliary and
emergency heat
• Fans: one speed
You can check your system’s compatibility
at nest.com/ca/works
Professional installation is recommended for
dual fuel systems (heat pump with furnace).

Don’t want to install your
Nest Thermostat yourself?
The Nest Thermostat is designed for DIY
installation, but you can also hire a Nest Pro
to do it for you. They’ll take care of installation
and make sure everything’s up and running.
Go to nest.com/ca/install to find a Nest Pro
installer near you.
1. Switch off power
This protects you and avoids blowing a fuse in your
equipment. To make sure the power is off, change
the temperature with your current thermostat
and wait at least five minutes to be sure that your
system doesn’t turn on.
2. Remove the cover
Some thermostat covers pop off, while others
need to be unscrewed. Older thermostats may
have a second plate that should also be removed
to expose the wires.
3. Take a picture of the wires
Take a picture of your thermostat’s wires and
save it for reference. Make sure you can read
the wire terminal labels.
IMPORTANT: If there are two labels on
your thermostat’s wire connectors, go
to nest.com/ca/labels for detailed help
and instructions.
Incompatible wiring and voltage
Stranded wires
Stranded wires aren’t compatible with the
Nest Thermostat.
High-voltage wires
If your thermostat is labeled 120V or 240V,
or has thick wires with wire nuts, or has
L1 and L2 terminal blocks, your system
is high voltage and isn’t compatible with
the Nest Thermostat.
If you haven’t already, go to nest.com/ca/works
and enter your thermostat’s wires into the
compatibility checker.
• Enter only the connectors on your
thermostat that have wires in them
• Do not use wire colors – enter the
connector labels
• Do not enter any jumper wires into
the checker (see step 5)
If your system is compatible, you’ll get a
custom wiring diagram that you will need
to install your Nest Thermostat. You can
print it or email it to yourself.
4. Use the compatibility checker
5. Remove any jumper wires
Jumper wires are short wires between two
connectors. The Nest Thermostat doesn’t
need jumpers. If your thermostat has jumpers,
remove them, but save them along with your
old thermostat.
IMPORTANT: If you have Rh and Rc wires, you have
a dual transformer system. The Nest Thermostat E
is not compatible with dual transformer systems,
but you may be able to use the 3rd generation Nest
Learning Thermostat.
6. Label the wires
Peel off the labels below and attach them
to the thermostat’s matching wires.
Note: If you have an Rc or Rh wire, put the
R label on it.
IMPORTANT: If you’re unsure about wiring
your thermostat, go to nest.com/ca/install
to contact a Nest Pro in your area.
Wiring tips
Wire colors can vary, but:
• Common or C wires are generally blue.
• If there’s an orange wire in the connector labeled both W and O/B,
then you likely have a heat pump. Put this wire in the Nest Thermostat’s
* O/B connector.
• If there’s a white wire in the connector labeled both W and O/B,
then you probably don’t have a heat pump. Put this wire in the Nest
Thermostat’s W connector.
After removing the thermostat base, gently wrap
the wires around a pen or pencil so they don’t fall
back into the hole in the wall.
Remember, the power to your HVAC system must
be off to avoid blowing a fuse in your equipment.
8. Mark where screws will go
Use the built-in bubble level to make
sure the base is level.
7. Disconnect wires and remove base
If you have an electrical box
Electrical boxes aren’t
common, but if you have
one, you’ll need to purchase
a steel plate and screws
from nest.com/ca for
installation.
Secure the steel plate to
the electrical box with two
of the screws. Use the other
two screws to attach the
Nest base and trim plate.
Optional in most homes
Use the included trim plate
if needed
If you don’t want to paint over
holes or marks left by your
old thermostat, you can use
the optional trim plate.
Snap the thermostat base
and trim plate together, then
screw the plate to the wall.
9. Install the Nest base
Pull the wires through the center of the base,
then attach it to the wall with the screws.
10. Connect wires
Use the wiring diagram you got from the
compatibility checker in step 4 to connect
your system wires to the Nest Thermostat.
Note: If you have an R, Rc or Rh wire,
you can put it into the R connector on
the Nest Thermostat.
If you have a W2, Y2 or O/B wire, you
can put it into the * O/B connector,
if needed.
The exposed wire should be straight.
3/8 in
Gently tug each wire to check
they’re secure, and make sure
each connector that has a wire
stays down.
After all the wires are securely
connected, push them down
to make sure they’re flush with
the base.
11. Attach the display
Push the display onto the base until it clicks.
12. Switch the power back on
14. Control it with the Nest app
Download the free Nest app so you can
control your thermostat with your
phone. You’ll also receive a monthly
Home Report that shows your energy use.
You can get the app on Google Play or the
App Store, or go to home.nest.com/ca if
you don’t have a phone handy.
13. Setup
The Nest Thermostat will turn on and
walk you through setup. You can select
a language, connect it to Wi-Fi, and
tell it some things about your home and
system so it can help save energy.
The Nest Thermostat doesn’t have
a touchscreen. Turn the thermostat
ring and press it down to select.
If you’re new to Nest, tap the plus sign
on the app home screen, then select
Nest Thermostat.
If you already have Nest products in
your account, tap the Settings icon,
then select thermostat.
The app will show you how to add your
thermostat to your Nest Account.

Vous n’avez pas envie d’installer
vous-même votre thermostat Nest?
Le thermostat Nest est conçu pour que vous puissiez
l’installer vous-même, mais vous pouvez également
engager un Nest Pro pour le faire à votre place. Il
s’occupera de l’installation et s’assurera que tout
fonctionne correctement. Consultez la page
nest.com/ca/fr/install pour trouver un installateur
Nest Pro près de chez vous.
Commutateur du système
ou
1. Débranchez l’alimentation
Cela vous protège et évite de faire sauter un
fusible de votre équipement. Pour vous assurer
que l’alimentation est bel et bien coupée,
modifiez la température sur votre thermostat
actuel et attendez cinq minutes pour vous
assurer que votre système ne démarre pas.
2. Retirez le couvercle
Certains couvercles de thermostat peuvent être
retirés à la main, alors que d’autres doivent être
dévissés. Les thermostats plus anciens peuvent
avoir une deuxième plaque qu’il vous faudra
enlever pour exposer les fils.
3. Prenez une photo des fils
Prenez une photo des fils de votre thermostat
et conservez-la pour consultation ultérieure
au besoin. Assurez-vous d’être en mesure de
lire les étiquettes des bornes de fils.
IMPORTANT : S’il y a deux étiquettes
apposées sur les connecteurs de fils
de votre thermostat, consultez la page
nest.com/ca/fr/labels pour obtenir
de l’aide et des instructions détaillées.
Tension et câblage incompatibles
Fils multibrins
Les fils multibrins ne sont pas compatibles
avec le thermostat Nest.
Fils à haute tension
Si votre thermostat porte l’étiquette 120 V
ou 240 V, ou s’il dispose de fils épais avec
capuchons de connexion, ou de borniers
L1 et L2, il s’agit d’un système haute
tension qui n’est pas compatible avec le
thermostat Nest.
Si ce n’est pas déjà fait, accédez à la page
nest.com/ca/fr/works et cochez les cases
correspondant aux fils de votre thermostat
dans le vérificateur de compatibilité.
• Cochez uniquement les cases correspondant
aux connecteurs de votre thermostat auxquels
des fils sont connectés
• Ne vous fiez pas aux couleurs des fils, mais
plutôt aux étiquettes des connecteurs
• Ne cochez aucune case correspondant à un fil
de liaison dans le vérificateur (voir l’étape 5)
Si votre système est compatible, vous obtiendrez
un schéma de câblage personnalisé dont vous
aurez besoin pour installer votre thermostat
Nest. Vous pouvez l’imprimer ou vous l’envoyer
par courriel.
4. Utilisez le vérificateur de compatibilité
5. Retirez les fils de liaison
Les fils de liaison sont des fils courts situés entre
deux connecteurs. Le thermostat Nest n’a pas
besoin de fils de liaison. Si votre thermostat
dispose de fils de liaison, retirez-les, mais
conservez-les avec votre ancien thermostat.
IMPORTANT : Si des fils Rh et Rc sont présents,
vous avez un système à double transformateur.
Le Nest Thermostat E n’est pas compatible avec
les systèmes à double transformateur, mais vous
devriez être en mesure d’utiliser le Nest Learning
Thermostat de 3e génération à la place.
6. Étiquetez les fils
Décollez les étiquettes ci-dessous et apposez-
les sur les fils correspondants du thermostat.
Remarque : Si vous avez un fil Rc ou Rh,
apposez-y l’étiquette R.
IMPORTANT : Si vous hésitez à câbler vous-même votre
thermostat, consultez la page nest.com/ca/fr/install
pour trouver un Nest Pro dans votre région.
Conseils de câblage
Les couleurs des fils peuvent varier, mais :
• Les fils communs ou fils C sont habituellement bleus.
• Si vous voyez un fil orange portant les étiquettes W et O/B dans le
connecteur, vous possédez probablement une pompe à chaleur.
Branchez ce fil dans le connecteur * O/B du thermostat Nest.
• Si vous voyez un fil blanc portant les étiquettes W et O/B dans le
connecteur, vous ne possédez probablement pas de pompe à
chaleur. Branchez ce fil dans le connecteur W du thermostat Nest.
Après avoir retiré la base du thermostat, enroulez
doucement les fils autour d’un stylo ou d’un crayon
pour les empêcher de retomber dans le trou du mur.
N’oubliez pas de couper l’alimentation de votre
système CVC pour éviter de faire sauter un fusible
de votre équipement.
8. Marquez l’emplacement des vis
Utilisez le niveau à bulle intégré pour vous
assurer que la base est de niveau.
7. Débranchez les fils et retirez la base
Plaque en acier
Si vous possédez un boîtier
électrique
Les boîtiers électriques ne sont
pas courants, mais si vous en
possédez un, il vous faudra une
plaque en acier et des vis, que
vous pouvez acheter à la page
nest.com/ca/fr, pour installer
le thermostat.
Fixez solidement la plaque en
acier au boîtier électrique avec
deux des vis. Utilisez les deux
autres vis pour fixer la base
Nest et la plaque de montage
à la plaque en acier.
Facultatif dans la plupart des résidences
Utilisez la plaque de montage
incluse (si nécessaire)
Si vous ne voulez pas peindre
les trous ou les marques laissés
par votre ancien thermostat,
vous pouvez utiliser la plaque
de montage facultative.
Enclenchez la base du thermostat
et la plaque de montage ensemble,
puis vissez la plaque au mur.
9. Installez la base Nest
Faites passer les fils par le centre de la base,
puis fixez celle-ci au mur avec les vis.
10. Branchez les fils
Utilisez le schéma de câblage que vous
avez obtenu du vérificateur de compatibilité
à l’étape 4 pour connecter les fils de votre
système au thermostat Nest.
Remarque : Si vous avez un fil R, Rc ou Rh,
vous pouvez le brancher au connecteur R
du thermostat Nest.
Si vous avez un fil W2, Y2 ou O/B, vous
pouvez le brancher au connecteur * O/B,
si nécessaire.
Le fil dénudé doit être droit.
0,95 cm
Tirez doucement sur chaque
fil pour vérifier s’il est bien
branché. Assurez-vous que
chaque connecteur qui est
relié à un fil reste abaissé.
Une fois les fils solidement
branchés, poussez-les vers le
bas pour vous assurer qu’ils
sont de niveau avec la base.
