LED Indicators

LEDs above the RUN, OFF, and AUTO buttons indicate
the mode of operation as shown in Figure 3-2.
The RDC2 controller also has a set of power system
LEDs below the pushbuttons. The power system LEDs
indicate which power sources are available and which
source is supplying power to the building (based on the
position of the Model RXT transfer switch).
Figure 3-1.
Note: The power system LEDs operate only if a Model
RXT transfer switch is connected. They will not
operate if a Model RDT transfer switch is used.
