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.
