When the HOLD LED is

flashes, the unit is

Now that you have a good idea where everything is on the faceplate of the
Series 920, continue to Chapter 3 for the Sample Program. If you skip the
sample program, do not forget to check the position of DIP switch #1 before
you begin programming your control after installation. With DIP switch #1
OFF, the 920 saves your program whenever power is removed (warm start).
With DIP switch #1 ON, the 920 will clear its memory of all programmed
information whenever power is removed, substituting default values (cold
start).
