11 PC, Modem PC CPU: Celelon (500 MHz) or higher-grade CPU Memory: 64 MB min. (128 M recommended) HDD: 6 GB (Free space of at least 1G) Monitor: At least 800*600 (256 colors) Windows: Windows 2000, Windows NT4.0 (SP4 or later version) (Windows95, 98 and Me are not supported) Do not use PC functions such as standby and sleep because the PC is used for continuous error monitoring. Modem Zoom, model 2948 or equivalent recommended. * The same type of modems must be used in the PCs and at the site(s) in order to maintain compatibility between these.

12 5. Q & A Is it possible to operate air conditioners at a moment s notice in cases where the room temperature suddenly rises? Yes, by sending a forced operation signal to the adapter with external sensors. However, the system does not communicate temperature errors and the like. * Contact your DAIKIN representative for details. Does the system require a backup power supply? Power supply for the adapter is taken from that intended for air conditioners so it depends on the A/C backup function. In order to protect the PC from accidental power failures, the installation of a UPS (uninterruptible power supply) is recommended. Is it possible to remotely monitor/control A/Cs other than SkyAir? RAs are not supported. Contact your DAIKIN representative with regard to any matters pertaining to VRVs.

13 Is it possible to use multiple PCs to monitor the system? No. The system is not designed to perform remote monitoring/control from a multiple number of PCs partly due to light structure concept. A single PC can adequately monitor/control up to 50 sites. Is it possible to connect the system to one unique to a specific customer? No. This system does not support connections between the DS-NET System and customer s host system. The customers can, however, develop their own monitoring system (software) by utilizing adapters. Please inquire with your DAIKIN representative for further details.

14 What is the difference between AIRNET and DS-NET? The DS-NET is a system that enables a customer to monitor/control its A/C system. Whereas, the AIRNET is a service whereby DAIKIN, instead of the customer, monitors the A/C system, which includes the detection of A/C malfunctions and prediction of possible errors. What is the difference between the intelligent Manager and DS-NET? The intelligent Manager and intelligent Touch Controller are systems used for the centralized monitoring and energy efficient control of a multiple number of A/C units installed in a building and the like.

15 DS-NET Adapter <DTA113A51> 1. Outline and Features Installing the DS-NET Adapter onto indoor units enables online A/C control and monitoring from a BMS via modem. Moreover, it enables automatic intermittent operation and backup operation of A/C units even when not using the remote function. The DS-NET Adapter controls indoor units connected to a maximum of three remote control lines (N,P). (Note) 1. The DS-NET Adapter cannot be used in combination with centralized control devices, Master Station II, D-BIPS or the like (because the commands compete). 2. The DS-NET Adapter cannot be used in combination with remote group control adapters (because they both function as sub remote controllers) 3. The DS-NET Adapter can be used with all available indoor units (comes with four types of power cables). 4. Once the DS-NET Adapter has been installed, two remote controllers cannot be used (because the adapter functions as a sub remote controller). 2.

18 6. Setting with the Remote Control Service Function In order to operate the DS-NET Adapter, it is necessary to use the remote control services to set the various operation modes Settings with remote control service function Bold lettering denotes settings when shipped from factory. Host Unit: Yes/No...Set as Yes when operating from a remote PC. Backup Control: Yes/No...Set as Yes when enabling the backup operation. Sequential Startup Control: Yes/No... Set as Yes when enabling the sequential startup operation. Automatic Altering Operation: 0~99...Sets the time interval for intermittent operation. Asterisk denotes no automatic intermittent operation. Guaranteed Minimum Operating Units: 1/2...Sets the guaranteed minimum number of units during automatic intermittent operation. Automatic Connection: No/Yes...When using the phone line for calls, this function can be set at No. On time alarm: 00:00~23:59...Sets the time at which system transmits signals. The time set when shipped from factory is 2:00. Backup Control When an operating A/C unit is shutdown due to power failure or malfunction (not including alarms or caution reports), the backup function starts up the same number of units that were operating before the shutdown. Once the A/C units that were shutdown due to malfunction return to normal operation, the backup function shuts down the units that were started up as backup. Sequential Startup Control The sequential startup control function, or 'sequential starting' prevents the flow of a large starting current when all A/C units are simultaneously started up in a case of total system operation. The function delays the start up timing of each of the units by some 4 seconds so the system's A/C units do not start up simultaneously. Automatic Intermittent Operation Control This is a function that controls A/C unit On/Off at predetermined time interval to balance out the amount of time each of units are operating. The operation pattern is determined according to the number of A/C units connected and guaranteed minimum operating units.

19 7. Considerations When Setting 1. The DS-NET Adapter cannot be used in combination with centralized control devices, Master Station II, D-BIPS or the like (because the commands compete). 2. The DS-NET Adapter cannot be used in combination with group remote control adapters. The reason for this is that the DS-NET Adapter and group remote control adapters both serve as sub remote controllers. In order to address this problem, the display of remote On/Off and malfunctions could be done at the connection using Sky Air connecting adapters and remote control adapters. It would receive the On/Off commands remotely during automatic backup operation and rotational operation. Furthermore, it would enable automatic operation when events triggering an automatic On- Off operation occur during remote start/stop. However, the following restrictions would apply in such a combination. This is based on the fact that the DS-NET Adapter is not connected to a central devices (which in this case refers to the remote control adapter). Therefore, even if set to prohibit remote controlled operation from the remote control adapter, start/stop of the indoor units can be controlled by the DS- NET Adapter. (The allowance/prohibition of set temperatures can also be controlled with the DS-NET Adapter.) 3. Once the DS-NET Adapter has been installed, two remote controllers cannot be used. (because the DS-NET Adapter functions as a sub remote controller) For the same reason explained in the above number 2, the DS-NET Adapter cannot be used in combination with two remote controllers.

21 DS-Net infrared remote control non-compatibility It should be clear that wireless remote controls cannot be connected to Daikin s DS-net system. The reason for this non-compatibility is explained as follows; When using a infrared remote control, the sub wiring line must be used for connection, however DS-net also requires connection to this line. If both devices occupy the one line the abnormal condition will occur. This is explained in more detail on page 51 in the D-BACS Design Guide ED Signal receiver Infrared remote control DSnet adapter (DTA113A51)
