Emergency operation pattern (3 outdoor units)
(2) Ending the emergency operation
1) End conditions
When one of the following conditions is met, emergency operation stops, and the unit makes an error stop.
When the integrated operation time of compressor in cooling mode has reached four hours.
When the integrated operation time of compressor in heating mode has reached two hours.
When an error is detected that does not permit the unit to perform an emergency operation.
2) Control at or after the completion of emergency operation
At or after the completion of emergency operation, the compressor stops, and the error code reappears on the remote con-
troller.
If another error reset is performed at the completion of an emergency mode, the unit repeats the procedures in section (1)
above.
To stop the emergency mode and perform a current-carrying operation after correcting the error, perform a power reset.
2. Communication circuit failure or when some of the outdoor units are turned off
This is a temporary operation mode in which the outdoor unit that is not in trouble operates when communication circuit failure
occurs or when some of the outdoor units are turned off.
(1) Starting the emergency operation (When the OC is in trouble)
1) When an error occurs, the error source and the error code appear on the display on the remote controller.
2) Reset the error via the remote controller to start an emergency operation.
Precautions before servicing the unit
When the OC is in trouble, the OS temporarily takes over the OC's function and performs an emergency operation. When this
happens, the indoor unit connection information are changed.
In a system that has a billing function, a message indicating that the billing system information has an error may appear on
the TG-2000A. Even if this message appears, do not change (or set) the refrigerant system information on the TG-2000A.
After the completion of an emergency operation, the correct connection information will be restored.
