1) If “Emergency stop (Level signal)” is selected, the air conditioning units in normal operation will stop when the contact
turns on. Even when the contact turns off, these units will remain stopped. They must be started up manually after the
emergency stop is reset.
2) If "ON/OFF (Level signal)" is selected, the air conditioning units that are stopped will start operation when the contact
turns on. Conversely, the units that are in operation will stop when the contact turns off.

1) If input pulse signal is the same as the current operation status of the air conditioning units, no status change will
occur. (For example, if an ON signal is input while the air conditioning units are in operation, the units will continue
their operation.)
2) If the operation from the local remote controller is prohibited, ON/OFF status, operation mode, or temperature setting
cannot be changed and filter sign cannot be reset from the local remote controller.
3) The pulse width (contact ON) should be between 0.5 and 1.0 second.
