LED (red × 2)
•
LED 1 and 2 blink alternately while automatic address setting is in progress.
•
Display the alarm contents for alarms that are detected by the outdoor unit.
LED (green): Power indicator
Indicates the DC 5V power on the outdoor unit control PCB.
2P plug (black) : Start pin
Short-circuit this pin and apply a pulse signal to start all indoor units in that
refrigerant system.
2P plug (black): Stop pin
Short-circuit this pin and apply a pulse signal to stop all indoor units in that
refrigerant system.
2P plug (black): Refrigerant recovery Pin
•
Short circuit this pin to perform refrigerant recovery control using cooling operation.
The indoor unit fan will operate at HIGH and 55 Hz for a maximum of 10 minutes.
When refrigerant recovery is completed, close the valves and open circuit this pin
to stop the operation.
3P plug (black): Indoor unit Heating/Cooling mode change pin
•
When operating the compressors to perform automatic address setting,
operation in Heating mode can be normally used. However, short-circuiting this
pin performs operation in Cooling mode. (Static signal)
•
Short-circuiting this pin during ordinary operation changes the mode from
Cooling to Heating (if the current mode is Cooling) or from Heating to Cooling
(if the current mode is Heating).
2P plug (black)
•
This pin is used to test the PCB at the factory.
•
When the power is turned ON after this pin has been short-circuited, all output
signals will be output in sequence. (Sequential output does not occur if this pin
is short-circuited when the power is already ON.) Releasing this pin returns the
unit to normal control.
2P plug (black)
Short-circuit during the test run operation.
Open the circuit after the test run.
