Avoid unexpected start times
It is possible to set a second start time that begins before the watering
cycle from the first start time has finished. When this happens, the start
of the second cycle is delayed until the first is complete; so the start
time may not occur when you expect it. In addition, increasing run time
with the water budget feature may cause an overlap that delays the next
scheduled start time.
Avoid watering on a non-watering day
A watering cycle that continues beyond Midnight will run to completion
regardless if the next day is scheduled for watering.
Avoid excessive watering
By default, Programs A, B and C can be scheduled to run concurrently
(overlap). This feature can be restricted by selecting the Program
Stacking option (see page 13). Start times entered for any program will
begin automatically when that time occurs. Using multiple programs
enables valve stations to water on different schedules or to provide
additional watering if one program is not enough. If you need extra
water, use more than one start time and/or use the Water Budget feature
to increase the valve station run time.
Avoid Creating a low water pressure condition
Start times assigned to different programs are independent. If you set
identical or overlapping start times, more than one valve station can run
at the same time. The total flow may exceed the available water supply.
To avoid this situation, allow more time between start times to reduce
the number of valves running at one time, and make sure that multiple
Programs do not have the same start times.
Establishing new lawns
Having short, multiple watering cycles each day is especially useful when
establishing a new lawn.
Help with electrical problems
The Rain Dial-R will display the station number and the word “FUS” if a
short-circuit on a valve station is detected. The detected station will be
bypassed, allowing the remaining operable stations to run in the Program
watering cycle.
