Irritrol Total Control Mode D'emploi page 11

At 2:00 a.m., Program A watering cycle starts. Station 1 turns on, runs for 10 minutes, and
shuts off. Station 2 turns on, runs for 10 minutes, and shuts off. Stations 4 and 5 operate
sequentially in the same manner, each running for their set run time. When Station 5 shuts
off, the watering cycle is completed for the fi rst start time. At 3:00 a.m., the watering cycle
starts again and repeats the same station-by-station watering sequence.
Note that we have 40 minutes total watering time per cycle in Program A. If we had
set the next start time at 2:30 a.m., the start time would have been delayed until 2:40
a.m., enabling the fi rst cycle to fi nish as programmed. This function is called "start time
stacking", and can occur within each program.
Watering programs, however, operate independently, which means that two or more
programs can run simultaneously. In our example, Program B will also start at 2:00 a.m.
Therefore, Stations 1 and 3 will turn on at the same time, and Station 2 will turn on while
Station 3 is running. This feature enables more watering to be completed within the prime
"watering window", which is generally between Midnight and 6:00 a.m.
NOTE:
When scheduling watering programs to run simultaneously, it is important to
ensure the water supply has suffi cient pressure and volume to maintain optimum sprinkler
performance.
Watering Schedule form (SAMPLE)
For your convenience, a Watering Schedule Form/Quick Reference Card is provided. Use
the form to plan and record your automatic watering activities. Use the quick reference
instructions when minor programming changes are required. Keep the card with the
