Therefore, at the end of day 1 (first 24-hours), the ems controller has set all the 30 minutes to ready (2) or saving (0)
depending on the outlet activity pattern as shown in the following example matrix:
ems controllers then copy the pattern learnt from day 1 to the remaining 6-days of the self-learning matrix, as
shown in the example matrix, below:
ems controllers with a 1-day learning period start switching to
the saving mode on the second day, (second 24-hours), if there
are sufficient saving (0) periods. ems controllers then continue
to update the self-learning matrix as follows:
• For periods set to ready (2), if no activity is detected change
to monitor (1). Otherwise, keep the period set to ready (2)
• For periods set to saving (0), if activity is detected change
to monitor (1). Otherwise, keep the period set to monitor (0)
At the endof week 1, the ems controller has updated the self-learning matrix for the outlet activity pattern as shown
below. Note that differences for activity patterns learnt on day 2 take two weeks to be implemented. Therefore, 1-day
learning periods are recommended only for outlets with regular patterns every day of the week.
