due to input signal coming from CN134.
• Emergency stop: When emergency stop is actuated, the indoor unit does not
accept the operation command from the remote controller. On the other hand,
when the emergency stop is released (no input from CN134), the air condi-
tioner does not return to the original operation until the indoor unit is turned on
by the remote controller.
