6.3 how a 1-day learning period works
ems controllers with a one day learning period, L P set to 0, run in the ready mode for 1 day, (24 hours),whilst the ems con-
troller 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.
At power-up, all the 30 minute periods are set to monitor (1) as shown in the following example matrix.
For periods set to monitor (1), ems controllers run in the ready mode.
ems controllers then update the self-learning matrix depending on how much activity is detected in each 30 minute period
as follows:
l if the ems controller detects activity during a 30 minute period, the ems controller changes the state from monitor (1) to ready (2)
l if the ems controller does not detect activity, the ems controllers changes the state frommonitor (1) to
saving (0).
Note:
l
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.
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) depend-
ing the outlet activity pattern as shown in the example matrix:
