Online Energy Management Control System
Infrastructure Components
Ethernet Coordinator
Each Ethernet Coordinator can support up to 100 Thermostats. The number of Ethernet
Coordinators is dependent on the layout and construction of property.
Ethernet Backbone
The successful communication with Ethernet Coordinators is heavily dependent on the
network they are attached to.
Server
The EMS Server receives temperature, door events, motion events, and other data from
the rooms. The data flows from the thermostats to the Ethernet Coordinators to the
Ethernet backbone to the EMS Server. The EMS Server also sends commands back up
to the thermostats.
Software Components
EMS Listener
The EMS Listener is the communications software that runs on the EMS Server and
writes data arriving from the rooms to the EMS Server Database.
PMS Interface
The energy saving aspects of the EMS system are very dependent on utilizing
information on when guests are checked in or out of the guest rooms. When the guest
rooms are unrented larger setbacks are utilized to gain more energy savings. And as
soon as a guest checks in, a command is sent from the EMS Server to the guestroom so
that the HVAC unit begins conditioning the room before the guest arrives.
