LED indication (Demand build)
The
EMU-2
™ has three Indicator LED Lights
arranged in a “stoplight” pattern; that is, red at the
top, yellow in the middle, and green at the bottom.
When the
EMU-2
™ firmware is factory-configured
for a Demand build, these lights indicate the current
rate of demand for power (in kW) relative to a
baseline.
The baseline is initially set to 0.5 kW, but can be
changed while in the
Current Usage
screen. To set
the baseline:
Navigate to the
Current Usage
screen using the device control buttons.
Adjust your usage by switching loads in your house on or off, until the
Current
Usage
screen shows the value you want to use for the baseline.
Press and hold the Top Button for 5 seconds. You should see all three Indicator
LED Lights come on together. This indicates that the baseline has been set to
the current usage rate shown on the screen.
After that, the Green light will be on when the current consumption rate is below the
baseline. When consumption is at the baseline rate or greater (up to 5x the baseline
rate), the Yellow light will be on. When consumption is more than 5x the baseline rate,
the Red light will be on.
