The ems controller then continues to run in the ready mode for the remainder of the 7-day learning period whilst
updating the self-learning matrix.
At the end of the 7-day learning period, the ems controller has a complete self-learning matrixas shown in the
following example matrix
6.3 How a 1-day learning period works
ems controllers with a 1-day learning period, (LP) set to 0, run in the ready modefor 1-day, (24-hours),whilst the ems
controller learns the outlet activity pattern such as opening and closing times.
ems controllers start self-learning the moment the ems controllers are first powered-up. A tpower-up, all the
30-minute periods are set to monitor (1) as shown in the example matrix below.
For periods set to monitor (1), ems controllers run in the ready mode.
ems controllers then update the self-learning matrix
depending onhow much activity is detected in each 30-minute
period as follows:
• If the ems controller detects activity during a 30-minute
period, the ems controller changes the state from monitor
(1) to ready (2)
• If the ems controller does not detect activity, the ems
controller changes the state from monitor (1) to saving (0)
Note
The amount of activity required to change the state from monitor (1) to ready (2) depends on
the setting of the activity frequency (AF) parameter.
