using Auto Adjust. NEXT RUN times will return to zero after
each watering day’s cycles are complete. Use the NEXT and
BACK buttons to review the NEXT RUN time for each zone.
6.3.2 DEFICIT
Deficit is the amount of water (displayed in inches) that needs
to be replaced for your plant material due to water loss
through evapotranspiration – evaporation from soil and tran-
spiration from plants. Your SmartLine
®
controller will calcu-
late the water deficit each day at midnight based on data
communicated to it by the SLW series weather station at
11:50 pm of the prior day. The water deficit will continue to
accumulate until the next scheduled watering cycle and will
return to a zero reading when watering is finished. The
SmartLine
®
controller uses an internationally recognized for-
mula called the Hargreaves formula for calculating evapo-
transpiration.
When Advanced Functions
is displaying DEFICIT, use
NEXT and BACK buttons to
view deficit for each zone.
The NEXT or BACK buttons
will also return you to the
DEFICIT level. When dis-
play is at the DEFICIT level,
you can then use the UP
arrow button to move to
NEXT RUN readings.
If you wish to reduce the deficit numbers, press and hold
down either the ▲ or ▼ arrow button for 5 seconds. This
allows you to use the ▼ arrow button to reduce the latest
deficit for the zone to as low as 0 inches.
Deficit is only available for review when you are using Auto
Adjust mode.
6.3.3 TEMPDATA
TEMPDATA provides the daily high/low temperature readings
in Fahrenheit (Celsius for export) from the SLW weather sta-
tion for the past 5 days. Press NEXT to view readings for the
prior day. Press NEXT again to view the readings from one
day before the prior day followed by the daily high and
daily low. Continue pressing NEXT to view up to 5 days of
temperature history.
6.3.4 TOTL RUN
TOTL RUN is the total run time for each zone since the date
shown (default date in the SmartLine
®
controller is January 1,
2000 shown as 01/01/00). You can review TOTL RUN for
either the Standard or Auto Adjust modes. After you select
TOTL RUN with the UP arrow button, use NEXT to view the
date when TOTL RUN accumulation began. Use NEXT again
to view the total run times for each zone.
You can use the NEXT and BACK buttons to move through the
zones. After you go through all the zone positions, use the NEXT
button one more time to take you back to the TOTL RUN screen.
