Lights (model -L)
The Calsense ET2000e Irrigation Controller provides four optional programs that can be used to control
various devices such as lights, gates, or water features. The additional light circuits are added at the time
of ordering by specifying the -L interface. This option includes the hardware and firmware for four
isolated light circuits. The Lights programs operate independently from the irrigation programs. The
output is 24 volt AC (VAC) and is used to operate a relay (Figure 42
). The program has a 14-day rolling
schedule with two start and stop times during each 24-hour period.
