6.1 what is the self-learning matrix?
The self-learning matrix is a 7 day (7 x 24 hour), matrix with each 24 hour period divided into 48 30-minute periods. Each 30-
minute period has a state that ems controllers use to determine the mode as follows:
l 0 indicates no activity: ems controllers normally run in the saving mode.
l 1 indicates a change in activity: ems controllers run in the ready mode.
l 2 indicates activity: ems controller run in the ready mode.
For example, the self-learning matrix below shows the following:
l Day 1 to day 3: the ems controller runs in the ready mode from 06:00 to 18:00.
l Day 4 and day 5: the ems controller runs in the ready mode from 06:00 to 20:00.
l Day 6: the ems controller runs in the ready mode from 08:00 to 14:00.
l Day 7: the ems controller remains in the saving mode.
Note:
l The self-learning matrix starts the moment the ems controller is first switched on and is not
synchronized with calendar days. However, the diagram below starts at 00:00 on Day 1 for clarity.
6.2 how a 7-day learning period works
ems controllers with a seven day learning period, L P set to 1, run in the ready mode for 7 days (7 x 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.
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.
