Thermostat is Disconnected 

Trane® XL824/850/1050 Wireless Smart Thermostats Only

If power or WiFi goes out at your home, your thermostat will automatically reconnect when the power or WiFi comes back up.  However, if power or WiFi is momentarily disrupted (i.e.: when your lights blink during a storm), it may cause the thermostat to disconnect but not reconnect to WiFi.  If the thermostat disconnects but does not automatically reconnect to WiFi, it can be manually reconnected.  

While the thermostat is disconnected, the HVAC system should continue to run any setpoints or schedules that were previously programmed into it. 

NOTE: You will need to be at the location of your thermostat to complete the following steps.

• Turn Wireless Off and On Again at the Thermostat:

1. 1. 1. On the physical thermostat screen, press Menu.
         
         
      2. Tap Settings.
         
         
      3. Select Network.
         
         
      4. Press Wireless ON/OFF to turn WiFi off.
         
         
      5. Leave WiFi off for at least 30 seconds to allow the thermostat to fully disconnect.
      6. Press Wireless ON/OFF to turn the wireless network back on.  It may take up to 30 seconds for WiFi to be restored and the thermostat to reconnect.
         
         

• Reboot the Thermostat:
  If the thermostat does not connect after cycling the wireless setting, please try rebooting the thermostat.  Rebooting the thermostat will not remove any previous settings stored in the thermostat.

1. 1. 1. MAKE SURE THAT THE HVAC SYSTEM IS IDLE BEFORE PROCEEDING!
      2. On the physical thermostat, press Menu.
         
         
      3. Tap Settings.
         
         
      4. Select Reboot and allow the thermostat to shut down and restart. Please be aware that this process may take several minutes to complete.
