LED indication (TOU 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 TOU build, these lights indicate the current
price tier. There can be up to 7 price tiers. For most
tiers, a single light will be on.
The top tier is always considered Critical Peak, and
is indicated by a double flash of the Red LED every
3 seconds.
If the number of tiers is 1 or 0, or if the price tier has not been set, then none of the
Indicator LED Lights will be on.

If the price is set manually using the Set Rate screen, none of the Indicator LED Lights
will be on while the manually set price is in effect.
Note that the Indicator LED Lights are also used to indicate that a new text message
has been received. In that case, the Red and Yellow LEDs will flash alternatively.
