Router Compatibility

The thermostat is only compatible with 2.4Ghz Wi-Fi networks.  

The Aprilaire Wi-Fi thermostat uses an 802.11b/g/n 2.4 GHz Wi-Fi alliance certified radio and is compatible with most residential 2.4 GHz Wi-Fi networks.  802.11ac networks are not supported unless they are dual band capable.

Dual Band Routers:

 Aprilaire Wi-Fi thermostats can be used with dual band access points or routers. Dual band access points or routers broadcast two (or more) wireless networks (SSIDs); one (or more) in the 2.4GHz band and one (or more) in the 5GHz band.  The Aprilaire Wi-Fi Thermostat is only able to connect to wireless networks operating in the 2.4GHz band (802.11 b/g/n radio). Please configure your dual band router to have two different SSID: one for the 2.4 GHz and one for 5GHz.  Connect the thermostat to the 2.4GHz SSID.

  • WPA2 (AES)

  • WPA/WPA2 Mixed Mode (AES and TKIP)

  • WPA (TKIP)

  • WEP (64/128bit - otherwise recognized by 10/26 hexadecimal characters)

  • Open

 WPA2 Enterprise is not supported.

If you have a router that uses the older WEP standard, you will not be able to connect the thermostat to your home Wi-Fi using your phone. However, you can still setup the thermostat using a computer. Follow these instructions:

  1. Confirm the Wi-Fi symbol on the thermostat is “strobing.”

  2. On your laptop, open Wireless Settings and connect to the Wi-Fi network that matches the SSID that is displayed on your thermostat ( Example: Aprilaire8620W000492)

  3. Follow this link: http://192.168.1.99/index.html.

  4. A pop-up may appear asking for your login and password. Enter admin for both.

  5. Select your home’s router and enter the router’s password.

  6. Once the Wi-Fi connection setup is complete, you will be able to access the Wi-Fi Thermostat from your phone.

  7. If the thermostat is already added to your account, you will be able to connect. If not, follow the instructions for adding a thermostat in the User Guide

You need at least 2 bars for reliable Wi-Fi connection between your device and thermostat. If you are unable to maintain this signal strength, try moving your router closer to your thermostat or disconnecting  other devices that operate on 2.4GHz. These include:

  • Baby monitors

  • Microwaves

  • Cordless phones

  • Bluetooth devices

  • Other wireless devices

Most standard routers can be set up to be a repeater, or you can purchase and install a Wi-Fi repeater.

All communication between your device and your thermostat is protected by industry standard TLS, 256-bit encryption.
