This allows review of each station, on each day of the week. If only dashes
--- appear, there was no watering for that station on that day.

UNFINISHED
Stations that watered completely will show the minutes that the sta-
tion ran. The number of cycles is no longer shown in versions 19 and
later.
A station that was watering when the Day End occurred will be marked
with the Day End Stopped! message.
Stations that were unfinished because of the Day End will show the
total minutes that they did run, and the Unfinished message.
If the station was never able to run it will show Unfinished, but only
dashes in the date and minutes fields.
Stations that were interrupted because the dial was moved will show
User Pause, meaning the dial was moved out of the Automatic posi-
tion.
ET System always uses Cycle and Soak. It is possible for a station to
have run some of its cycles before the Day End. It will show minutes
for the run time, but still show Unfinished if not all the cycles were
completed.
What Happens to “Unfinished” Stations
Unfinished zones will continue to accrue a watering deficit.
The ET System knows they did not replenish completely, and on the
next legal watering day it will try to replenish all lost moisture, includ-
ing the deficit from the previous Unfinished day. It will begin the next
legal watering with the zone that was interrupted last time.
However, it is possible in extreme conditions with severe watering
restrictions that some zones will remain starved for moisture, until the
restrictions are eased or the weather cools.
Unfinished Watering solutions
Verify that Start Times, No Water Time and No Water End times, and
the Day End are set correctly. These define how many legal watering
hours the system has to complete irrigation.
ET System automatically calculates Cycle and Soak periods for each
zone, based on soil type, slope, and precipitation rate of the sprin-
klers.
Set a lower ET Adjust percentage at the ET Setup dial position. ET Sys-
tem is shipped set to 80% of ET, and a lower setting will use a smaller
amount of evapo-transpiration loss to calculate new watering.
Slope setting: In extreme conditions, it is possible to “fool” the
system into insuring that all zones get at least some water, by
increasing the slope percentage for each zone.
This will cause more,
and shorter, cycles for the zones, increasing the chances that all zones
get at least some water.
ET System will calculate shorter Cycle times and longer Soak periods
due to the slope, and move on to the next zone. This will cause all
zones to have their total run times broken up into smaller cycles, and
may, with careful adjustment and observation, fit some water for each
zone into severely limited watering times.
Planting low water use plants is another possibility, if these conditions
are frequently encountered.
Soil amendment may also increase water infiltration and holding
capacity.
Keeping irrigation hardware (sprinklers, nozzles, bubblers, and drip
emitters) in good condition is vital in ET-controlled irrigation. ET
controllers assume proper sprinkler performance and there is no
