<Additional Explanation>
-
When the airflow rate for the Sky Air is changed to ‘Medium’ with ‘Airflow Rate Setting Report’ , it is monitored as ‘Low’
(anything below 4) because the ‘Medium’ command from the R/C is ‘3’.
- The operation mode during Auto Mode is monitored as either cooling, heating or ventilation.
- In terms of Error Status and Error Code monitoring, no message is sent/reported when the malfunction/error does not
impede operation. (swing flap malfunctions, etc.)
- With regard to ‘*10. Even for A/C units without R/Cs, this appears as if a ‘Rejection’ setting has been conducted’ , it
would be meaningless and unlikely that a message prohibiting R/C operation would be sent to a A/C units that does
not feature an R/C. However, if the LON monitoring node were to refer to a value, it would read the message as
‘Control Rejection’ setting.
- Out of the 27 items listed on the previous page, 23 are individual items and 4 are items pertaining to the entire system.
Be sure to determine the contents and number of control items based on the selection from the 23 individual items.
