Learning installation mode and learning duration
There are two learning installation modes:
Manual: the meter learns the applicable values but does not begin using the learned values. The learned values are recorded for review, and you can decide to use the learned values or adjust them as required before manually implementing the learned values.
Automatic: the meter learns the applicable values and begins using those learned values automatically at the end of the learning period. If a learned value is invalid, the meter does not apply the value, but the value is recorded in the event log.
You can configure the maximum learning duration. The actual learning duration may vary, depending on the stability of the system. If the system is stable for a period equal to one quarter of the maximum learning duration, learning is complete; otherwise, the learning period will be the maximum learning duration.
Example: Setpoint learning duration in a stable system
In this example, the learning duration is 30 days. When the system is stable for 7.5 days (one quarter of 30 days) learning is complete.
Example: Setpoint learning duration in an unstable system
In this example, the learning duration is 30 days. Because the system is not stable for 7.5 days (one quarter of the 30 days) learning is complete at the end of the maximum learning duration.
