Video: What is the small C mean in the upper right corner of the LTMCU display for TeSys T controller?

Published date: 30 October 2018

Troubleshooting C Status on LTMCU Display for TeSys T Controller

Product Line:



When you are in system config mode, you will see a small "c" in upper right corner of LTMCU.  This would mean that the unit can be programmed.  This also means that the unit cannot be commanded to run unless the system is out of configuration mode.

To adjust this status mode from the keypad.  
  • Arrow down to services and enter.
  • Arrow down to config and enter.
  • Press enter on end config.  
  • Arrow down to yes and enter.
  • This will now hide the C on top right corner which confirms that you are no longer in config mode.
