•   if the thermostat is connected to a Wi-Fi network 
•   if the thermostat is not connected to a Wi-Fi network 
Except for the SETUP WI-FI screen, which can be changed from NO to YES, the information in the Wi-Fi settings 
screens is read-only and cannot be changed.    
The Wi-Fi screens have a fixed timeout of 60 seconds. 
 
Connect to a network 
If the thermostat is not connected to a Wi-Fi network and NO is displayed on the SETUP WIFI screen, follow these 
steps to connect the thermostat to a network: 
1  Press the SELECT button. 
2  Change NO to YES. 
3  Press SAVE.  
NOTE This puts the thermostat into the setup mode and ready to receive Wi-Fi join commands. 
The thermostat is already in the setup mode if SETUP WI-FI was changed from NO to YES in the past 2 minutes or 
if the installer disconnected from a Wi-Fi network in the past 2 minutes. 
The following screen indicates that the thermostat is ready to join a Wi-Fi network. If the thermostat is connected 
to a Wi-Fi network, the SETUP WI-FI screen is not displayed. 
 
NOTE  The SELECT button is not displayed because the thermostat is already in the setup mode. 
SSID 
When the thermostat is not connected to a Wi-Fi network, the SSID is a factory-configured value that starts with 
CMML followed by 12 numbers. The SSID scrolls across the top of the display for 5 seconds and then displays only 
the 12 digits for the remainder of the screen timeout time. The user needs these 12 digits to connect to the 
Carrier Connect Mobile App. 
SSID - Scrolls for the first 5 seconds                
CMML- Scrolls after 5 seconds 
When the thermostat is connected to a Wi-Fi network, the network SSID is displayed.
