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).
