Appendix F Local Control

Automatic Alternate Operation

According to the number of air conditioner systems connected and the minimum guaranteed number of units in operation, all the air conditioners are operated and stopped at certain intervals (alternate operation intervals) so that the operating hours of each air conditioner can be equalized.

Automatic alternate operation of the air conditioners is not performed while air conditioner errors are detected.

When the air conditioners are in automatic alternate operation, the air conditioners may not respond to the remote controller or remote instructions.

Note:

When the forced operation signal is input, all air conditioners will be in operating mode, and the air conditioners will start forced operation, to which priority is given over automatic alternate operation, the remote controller, or remote instructions. The foregoing applies to the forced stop signal in the similar manner. Higher priority is given to the forced stop signal over the forced operation signal.

Backup Control Operation

Overview

If an air conditioner comes to a stop due to a power failure or malfunction (excluding any alarm or warning), another air conditioner will be operated in order to keep the number of air conditioners in operation.

If the air conditioner that has come to a stop starts operating again, one of the air conditioners in operation will be stopped so as to keep the number of air conditioners operating before the occurrence of the power failure or malfunction.

Remote controller operation may be ignored while the backup control operation is active.

Sequential Start Control Operation

Overview

A very high starting current will flow immediately after the DS-NET software transmits a start instruction simultaneously to all the air conditioners connected to the DS-NET Adapter units and the air conditioners start operating together. The sequential start control operation adjusts the start timing of each air conditioner to suppress the starting current and prevent all the air conditioners from starting simultaneously.

• The sequential start control operation is available only if the system is connected to the PC to execute the DS-NET software.
• The sequential start control operation does not work for Personal Home Use with the GSM modem employed.
• The sequential start control operation adjusts the start timing of each air conditioner and prevents all the air conditioners from starting simultaneously.
• The DS-NET software cannot make setting changes to enable or disable the sequential start control operation. Use the remote controller in service mode instead. For details, refer to the Installation Manual.

Start Timing of Sequential Start Control Operation

• The DS-NET Adapter starts each of the connected air conditioners in sequence at approximately 4-second intervals after a delay according to the adapter address (ADR) when the start instruction is received.
• The delay time is a minimum guaranteed time, which may be extended according to the connected system or operation timing.

Forced Start/Stop Operation

Overview

Air conditioners can be forcibly started or stopped with an external forced start or forced stop signal input into the DS-NET Adapter.

Priority will be given to the forced stop operation if forced start and forced stop signals are input simultaneously.

Contact type: Normally closed

Detection condition: Level sensing

Forced Start Operation

When the forced start signal is ON, all air conditioners connected to the DS-NET Adapter will be set to run state. Furthermore, if a stop instruction is transmitted from the PC or stop operation is performed by the remote controller while a forced start signal is ON, priority will be given to the forced start operation and the air conditioners will operate.

The air conditioners started with a forced start signal turned ON will continue operating when the forced start signal is turned OFF.

The following conditions, however, apply.

• If a forced stop signal is ON, priority will be given to the forced stop operation.
• If a malfunction occurs, priority will be given to the stop operation activated with the malfunction detected.

Forced Stop Operation

When a forced stop signal is ON, all air conditioners connected to the DS-NET Adapter will be stopped.

Furthermore, if a start instruction is transmitted from the PC or start operation is performed by the remote controller while a forced stop signal is ON, priority will be given to the forced stop operation and the air conditioners will be stopped.

The air conditioners stopped with a forced stop signal turned ON will be continuously in the stop state when the forced stop signal is turned OFF.

The following conditions, however, apply.

- The forced stop operation takes precedence over the forced start operation.
