The AC and UC modes are applied to control individual smart sockets following automatic control policy and
user-defined control policy, respectively. Like the exclusion
between PTC and ELC modes, at any instance, either AC
or UC can be used to control a smart socket. The RECoS
in its AC mode determines the on/off state of a smart socket
based on the socket's energy usage history in the last 4weeks.
The RECoS in its UC mode provides an interface with
which users can flexibly set up the on/off state of a certain
socket. Note that the AC/UC mode of a smart socket can
co-exist with the PTC/ELC mode of the energy controller.
For example, the energy controller of a house is now in its
PTC mode, and a smart socket in the house is in its UC mode
or AC mode. Details of AC and UC modes will be described
later.
