Top Button cycles through the different options to select, and pressing the Bottom
Button saves the selected option and pages to the next screen.
Your
EMU-2
™ communicates wirelessly with the smart meter to get usage information,
and presents this information on the Display. The accumulated usage information is
updated every 4 minutes while the unit is in Active Mode. If the electricity price per kWh
is provided by the smart meter, the price is checked every 2 minutes.
Your
EMU-2
™ checks every 2 minutes for a new text message from your utility. An
envelope icon is shown in the upper left hand corner of the screen if there is an active
message stored on your
EMU-2
™.
The quality of the wireless signal from the smart meter is indicated by the small bar
graph in the upper right hand corner of the Active Mode screens. Four bars are shown
for a good signal; fewer bars indicate a lower quality signal. If the connection to the
smart meter is lost, a
large “X” will replace the bar graph.
There are also a number of configuration screens. These are accessed by pressing
and releasing both buttons simultaneously to put your
EMU-2
™ into Configuration
Mode. Note that your
EMU-2
™ should have successfully connected to the smart meter
before putting it into Configuration Mode.
There are Indicator LED Lights to the left of the Display that various status conditions.
Normally, the green LED should be on while the
EMU-2
™ is in Active Mode and Rest
Mode. When there is a new text message waiting to be read, the red and yellow LEDs
will flash in an alternating pattern. If supported by the meter and your utility, the
Indicator LED Lights will also indicate pricing levels.
The
EMU-2
™ displays your immediate energy usage on the
Current Usage
screen.
Use this screen like a speedometer for your home; it shows you how fast you are using
energy right now. This screen reacts quickly to changes in electricity use, so you can
observe changes in real time and see what a difference it makes when you turn
electrical loads on and off.
Your
EMU-2
™ also keeps track of your energy usage over time. The
Daily Totals
screen displays the total cost and usage, as well a graph of usage for each hour, for the
previous day and the current day so far. This allows you to spot patterns in your daily
electricity use, and to compare one day to the next.
The
Total to Date
and
Previous Totals
screens give you information about your energy
consumption over longer periods of time. By default, they are set to record your
accumulated usage each month, so the
Total to Date
screen shows your total usage so
far this month, which you can compare to last month’s usage in the
Previous Totals
screen. You can use the
Set Accumulation
screen in Configuration Mode to switch the
accumulation to manual, which allows you to start and stop your own custom
accumulation periods
– just like a stopwatch.
