1 Introduction

Thermostat installed on wall.

We will guide you through the initial setup for your Honeywell smart thermostat. Before we begin, we should first determine how far you are along with the installation. If you've already installed the thermostat on the wall, then we can proceed to the initial setup and registration. If the thermostat isn't installed yet, we recommend having a professional install it and then returning here later.

Thermostat installed on wall.

We will guide you through the initial setup for your Honeywell smart thermostat. Before we begin, we should first determine how far you are along with the installation. If you've already installed the thermostat on the wall, then we can proceed to the initial setup and registration. If the thermostat isn't installed yet, we recommend having a professional install it and then returning here later.

In order to connect to a wireless network, you must have the required credentials. These are:
  • Wireless Network Name (SSID)
  • Wireless Network Key (Password)

Finding Network Credentials

Most wireless routers or gateways have a label with the default credentials. If the credentials aren't there, check the documentation that came with your device.
Default Wi-Fi credentials highlighted on router / gateway sticker.

If your Internet Service Provider (ISP) installed the wireless router or gateway, they might have left you a setup sheet which may have the credentials.

The thermostat gets its power from the wiring in the wall that connects it to the home's heating and cooling system. If it is wired correctly and the circuit it is connected to is live, the device should be powered up and waiting on the initial setup.
