The ICC2 model controller can be upgraded to Centralus software for web-based central control options. Installing the WiFi module kit (WIFIKIT) will allow access to all of the Centralus features.
IMPORTANT: Prior to installing the WiFi kit, it is recommended to make a note of the serial number located on the inside of the module. This is referenced in the video above.
