How To Install A Nest Thermostat E

Before installing your new Nest thermostat, it’s important to switch off the power supply to your heating. This keeps you safe, and prevents accidents and electrical hazards.

Next, head on over to the thermostat you’re going to be replacing and remove the cover. While models differ, most allow you to easily pop off the cover or remove using a screwdriver.

Now that you’ve removed the cover, it’s a good idea to double check that it’s compatible with your power supply. There are a couple of easy ways of doing this:

• Take a look at the exposed wires. If your current thermostat is wired in with stranded wires - made up of several thin wires which are twisted together - then the Nest thermostat isn’t compatible.

• If your current thermostat is labeled as having either 110V, 120V or 240v of power output then, as with the stranded wires, the Nest thermostat won’t be suitable as you have a high voltage system.

Before moving on to the next step, take a quick photo of the wiring which you’ll use as a point of reference when installing the Nest thermostat. Make sure you can easily read the terminal labels.

Jumper wires are short lengths of electrical wire that connect to two different points. If you have any connected on the base plate, you can remove these as the Nest thermostat doesn’t require them.

Disconnect the wires from your old thermostat and remove the base plate by unscrewing it from the wall. Take care and make sure the exposed wires coming from the wall don’t slip back through.

Once you’ve removed the old base plate you may be left with holes from the screws, now’s a great time to fill these holes and apply a fresh coat of paint. 

Alternatively, you can hide the holes by covering them with the trim plate, which was included with your Nest thermostat.

Take the Nest base plate and hold it up against the wall, use the inbuilt level to ensure it’s straight and even. Use a pencil to mark where the screws will go. 

Next, using the screws provided in the Nest kit, secure the Nest base plate to the wall where your old thermostat was mounted. Be sure to pull the wires from the wall through the centre hole of the base plate and don’t tighten the screws too tightly as this could damage the sensors within the base.

Match the wires from your heating system to the corresponding terminals on the Nest Thermostat E base plate. Refer to the photo you took earlier for the correct connections. Next, gently press down the connector button and insert the corresponding wire, making sure it’s pushed all the way in. 

Once you’ve inserted all the wires, check to make sure that the connector buttons stay down then push the wires towards the wall so they remain flush - this will ensure the cover can be fitted with ease.

Once all the wires are securely connected, attach the display cover onto the base plate ensuring the Nest logo is at the bottom. It should click into place.

Now that you’ve successfully installed your Nest thermostat, you’re ready to turn the power back on and move onto setup.
