Energy Management System (EMS)
Screen images may vary slightly with continuous
improvements/firmware updates
The Energy Management System (EMS) is a function
of the Firefly Multiplex system. The electrical screen of
the central Multiplex panel (example above) displays
EMS data�
The system monitors the total current draw of the
coach’s 120 VAC power system� When running multiple
appliances or turning on devices like coffee makers
and vacuums, the system will temporarily shed other
loads (reduce/throttle back power from certain devices)
like the heating/hot water electric element to prevent
nuisance breaker tripping�
Upon decreasing the additional demand, and
approximately 2-3 minutes pass, the system will
automatically power up appliances and components in
reverse sequence�
Load shedding occurs in the following sequence
depending on the demand:
1� DC converter output is throttled to control the
converter AC input current requirements
2� Heating/Hot Water System Electric Element
3� Air Conditioner Compressor
4� Microwave
5� Cooktop (Galley Popup Outlet)
The number of appliances and devices the system can
run simultaneously depends upon available power�
With a 15A shore connection, you may be limited to
one or two appliances before the EMS will begin to
shed loads�
Navigate to the electrical screen on the multiplex
touchscreen panel to view Power Source and EMS
data; see Multiplex System on page 5-20 �
Outlets and USB ports
There are several outlets with 120V receptacles inside
and outside of your coach� At the base of the second
row seating you will find an outlet with USB charging
ports
The galley countertop has a retractable flush-mounted
popup outlet with 120V receptacles (to plug in the
cooktop and other appliances/devices) and USB
charging ports� Press down on the top to pop the outlet
out of the countertop socket and raise it to lock into
the extended position� To close, press the black tab
at the bottom to release the lock while pressing down
to close and lock in place� The outlet is self-contained
and sealed should any spillage occur around its casing�
However, use the same caution you would with any
electrical outlet; see Electrical Appliances and Outlets
on page 2-2�
NOTE
Only plug the cooktop into the popup countertop
outlet otherwise it may trip a breaker. The popup
outlet is controlled by the EMS and was designed
with cooktop use in mind. Depending on use of
other 120 VAC appliances and outlets, temporary
interruptions in service may occur (see EMS on
this page for more information).
