Unfinished Watering
With a large system and dry weather, it is possible that the No Water
Times and Day End settings that are too short to complete all the
watering calculated for the zones.
When the No Water Time interrupts watering, the display shows Water
Window Pause. This means there is still unfinished watering that will
resume after the No Water Time ends.

DAY END STOPPED!
STATION 06
CHECK HISTORY
Do not move the dial from the Automatic position while the unit is in
Pause mode.
When the No Water End is passed, the system will resume irrigating
where it stopped at the start of the No Water Window, and attempt to
complete all watering.
If the Day End is reached with Day End Stop set to Y, and there is still
unfinished watering, the system display will show Day End Stopped!
and Check History. Check the watering histories to see which zones
were missed, for special attention.
Rain Setting
The Rain Setting position determines how much natural rainfall is
required to stop irrigation. A minimum amount is preset, and it is not
necessary to adjust anything at this dial position for initial setup.
The ET Sensor is equipped with a “tipping bucket” style rain sensor.
Rain is not used directly in the calculation of ET, but it can be used to
a) shut off the irrigation, and b) adjust the next application of irriga-
tion, by deducting a percentage of the naturally occurring precipitation
(some rainfall is assumed to run off before absorption into the soil,
and a loss factor is included).
dial is turned to any other position, watering will be terminated and
will not resume!
Day End
Day End is normally set to midnight (12:00AM). Watering that starts
on a legal watering day is often allowed to cross over midnight, and
when this is desired, set Day End Stop to N (no).
If Day End Stop is changed to Y (yes), the watering is not allowed to
cross over into the next day, and all further watering will be cancelled
until the next legal watering day.
You can also change the Day End time, if watering must be stopped
before midnight.

This can actually create two separate water windows within a day.
For example, if you are allowed to water until 10 PM but not after:
Use the arrow buttons to move to the Day End setting, and use + or –
to change the day end time to 10:00 PM.
Use the arrow buttons to move to Day End Stop, and use + or – to
change to Y.
START: 03:00AM
NO WATER TIME: 08:00A
NO WATER END: 8:00P
DAY END: 10:00PM
DAY EMD STOP?: Y
You must set Day End Stop to Y, to prevent watering past the end
time!
Watering will then be permanently stopped for the day at 10 PM.
