An iComfort thermostat that won't connect to wi-fi can be fixed by following the instructions in the owner's manual. It is also useful to contact the Lennox dealer that installed the thermostat or to call 1-800-9-Lennox for assistance if basic steps do not help.
To connect the iComfort wi-fi to an available wireless network, press the button marked "Wi-Fi" on the thermostat's control panel then press "enable Wi-Fi". After reading over the terms and conditions for the iComfort, press "Agree" to proceed to the next step. Select the network that is being used from the list of available networks, or enter the network information manually if the correct one doesn't appear on the list. Enter the password for the wireless network being used, and press "Connect" to finish the connection process.
Once the iComfort thermostat is connected to wi-fi, it is registered to let the user gain access to the myicomfort.com website. The representative from the Lennox dealer completes the first part of the registration process by entering the company's contact information and the system specifications of the device. Registering the iComfort thermostat allows the dealer to monitor the system so it receives alerts when maintenance to the product is required.
