Problem

[Emergency Stop (Level signal)] is displayed on the screen, and the controller does not respond to the ON/OFF button.

If the external input interface receives an emergency stop signal, all indoor units and the LOSSNAY that are controlled by the TC-24A will stop. The TC-24A controller, low-level system controllers, or local remote controllers will not respond until the emergency stop signal input is removed. When the emergency stop signal is removed, the operation status before the signal was received will be restored.
