What Makes the Nest E Special?

With the 3rd Gen Nest being present in the market, you might be thinking, why should you buy the Nest E? Well, there are actually quite a few reasons for that.

It features a lot of the things you get in the 3rd Gen one, but at a lower price. Features like ready-to-go schedule, compatibility with all smartphones as well as smart home devices, energy-saving abilities, Nest home network, etc., are what make the Nest E stand out.

How to Install It?

Installing the Nest Thermostat E is actually pretty simple. But the first thing we need to make sure of is if your house has an HVAC system. An HVAC system is the heating-ventilating-air-conditioning system of your house.

Most houses have it, so it should not be an issue. However, not all thermostats are compatible with all kinds of HVAC systems. So before you go ahead and buy the thermostat E, make sure that the HVAC’s wiring matches with it.

We will be providing the nest thermostat E wiring diagram to help you understand whether it will be compatible or not.

After you have installed the device to the HVAC system of your house, you now have to set up the app. Honestly, it is just all in the app for controlling the temperature of your house.

Power on the device and turn on your phone’s Wi-Fi network. You will be required to download the Nest app, and then the devices will be connected. Running the entire process of setting up should not take anything longer than 10 to 15 minutes.

After setting up the app, you can use it to set your desired temperature and leave it to the thermostat to maintain that temperature throughout the day.

Before you take a look at the wiring diagram, there are a few things you need to know about the wiring of the heat link of the Nest thermostat E.

If you already owned a thermostat, you need to check whether that one had more than two wires. In case it did, you will have to identify them in order to finish the installation process correctly.

Find the OpenTherm wires of the current thermostat (OT1 & OT2) or the Common wire and Normally Open wire (C and NO wires). Once found, attach them to the heat link and see if there are any extra wires. If so, attach them to the terminal blocks.

To help you identify wires and make it easier to install the heat links of your Thermostat E, here is a table of the wire systems of different thermostat models and brands (if you already own one).
