Frequently asked questions
Q Where can I find my MAC ID and MAC CRC codes? :
: A The MAC ID and MAC CRC numbers are included on a card packed with the thermostat or on the
back of the thermostat (visible when removed from wallplate). Each thermostat has a unique MAC
ID and MAC CRC.
Q My thermostat is unable to register to the Total Connect Comfort website. :
: A Verify that the thermostat is correctly enrolled on your home Wi-Fi network. The message center
will display Wi-Fi Setup or Register at Total Connect. You might also see the Wi-Fi Signal strength
icon. Verify that the Wi-Fi router has a good internet connection. On your computer, verify that
you can open the site at mytotalconnectcomfort.com
