At the end of the ready mode, EMS controllers switch to the saving mode. However, the delay to saving
(dS) parameter can delay the switch to the saving mode. The delay helps ensure that, for example,
the EMS controller remains in the ready mode during periods without activity immediately prior to out-
lets closing for marketing purposes.
For more information about the parameters used in ready mode:

6.11 How the self-learning matrix updates after the learning period
EMS controllers continuously updates the self-learning matrix after the learning period as follows:
l If a ready period (2) does not have the minimum number of door openings or motion counts, the EMS
controller sets the period to monitor (1).
The EMS controller runs in the ready mode for periods set to monitor.
l If a monitored period (1) does not have the minimum number of door openings or motion counts, the EMS con-
troller sets the periodto saving (0). Otherwise, the EMS controller sets the period to ready (2).
l If a saving period (0) reaches the minimum number of door openings or motion counts, the EMS controller sets
the period to monitor (1).
For example, the self-learning matrix below shows monitor (1) periods during periods with and
without activity.
Note:
l If activity occurs in a saving period (0), such as a motion detection or a door opening, the EMS controller
switches the cooler lights on and sets the period to monitor (1).
However, the EMS controller does not start the compressor to cool the product.
