This requires connecting to the thermostat as an access point for initial configuration using a Wi-Fi
enabled laptop/computer/tablet/smart phone. Look for the BASstat- 221C-BW2 with its unique SSID of
"WiFi-122B-xxxx" and no access point passphrase by default (simply click to connect to Access Point).
The digits "xxxx" in "122B-xxxx" are the last 4 digits of the thermostat's Wi-Fi chip MAC address found
written on the back side of the Wi-Fi module.
This ensures a unique SSID for discovery and configuration and it can assist in identification of
thermostats when multiple Wi-Fi stats are installed on the same site (unique identifier outlined in blue in
the image below). This unique identifier can also be viewed in Engineering Menu item (Phy3).
Once connected to the thermostat as an access point, open its web page by typing its default address of
192.168.0.1 with admin for username and no password. Web page pictured below will be presented for
IP Network Configuration. The default IP configuration is shown below.
