4. Collection and Playback of Data on Checker
Caution 1. Be sure to check the Nos. of system and indoor unit of the system, on which a malfunction
occurs.
• Example of checking method
If the centralized address is known — Carry out some operation (e.g. ON/OFF or set value
changing) from the centralized remote controller
and define the unit, which presents changes on the
Checker.
If the centralized address is not known — Carry out operation from the remote controller
for indoor unit and define the unit, which
presents changes on the Checker.
2. In order to collect data using the DIII-NET, check with the customer that “Forced thermostat
OFF” is surely activated once.
• Provide the customer with an explanation that the system stops for a period of five minutes
at maximum and is automatically restart as soon as data is accepted.
3. Check to be sure the display time and settings on a personal computer.
• Since time displayed on the Checker is corresponding to that displayed on the personal
computer, be sure to check and change the time.
• If settings of screen saver and energy saving are made, there may be cases where the
personal computer freezes. Be sure to cancel the settings in advance.
4. Be sure to secure longitudinal data.
• Be sure to check and take notes of on-site works and the times when malfunctions occur,
which will be needed to play back the data. Furthermore, it is advisable to check and take
notes of any minimal works or changes.
5. Playback of data
• Verify collected data by yourself once.
It is the best to diagnose the data on site where the data was collected, while referring to
operation data and refrigerant circuit diagram. Furthermore, since it takes time to verify
data at offices, be sure to request for the customer to allow the verification time with an
explanation about the reason.
The nearest way to enable data analysis by yourself is to have your own view on the
collected data. If you always consult someone from the beginning, you will not develop the
ability to analyze data.
