- AUTO TUNING during Heating/Cooling output.
AUTO TUNING of Heating/Cooling output can calculate as the same way by using Heating/
Cooling output.
The I.D value of AUTO TUNING will be recorded as the same value for Heating/Cooling Side.
- Display during AUTO TUNING.
Main LED is blinking 500ms with time interval.
- Change SP value during AUTO TUNING.
If the SP is changed during AUTO TUNING, the Tuning Point is maintained. After AUTO
TUNING, it starts control for changed SP value.
- Change PID parameter during AUTO TUNING.
It can be changeable for PID value during AUTO TUNING however, it obtains by calculation
automatically after AUTO TUNING. But, when compulsory ending of AUTO TUNING except
normal operation, it is controlled by changed PID value.
- When abnormal Ending of AUTO TUNING.
① Compulsory Ending of AUTO TUNING.
② Input Sensor Open (S.OPN)during AUTO TUNING.
③ Measuring Cycle of AUTO TUNING is exceeding 24hour.
④ Change control mode to Manual(MAN) during the operation.
The parameter to setting for proportional PID value by obtaining AUTO TUNING.
Reduce AT-G, Cycle time became rapid and, Increase AT-G, control status
became more stable. If it is smaller, hunting become more and more.
