6.2 How a 7-day learning period works
ems controllers with a 7-day learning period (LP) set to 1, run in the ready modefor 7 days (7 x 24 hours), whilst the
ems controller learns the outlet activity pattern such as opening andclosingtimes.
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 thenupdate the self-learning matrix depending
on how 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.
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:
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.
