What Wi-Fi network requirements does the Bliss Chrono Thermostat need to connect?

The thermostat requires a 2.4 GHz Wi-Fi network with WPA2/PSK encryption; 5 GHz only networks are not supported, though routers broadcasting both frequencies are accepted. The thermostat does not work on corporate (enterprise) networks, and you must respect uppercase, lowercase letters, and special characters in the SSID and password. (Pages 17, 18)
