• 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 fea-
ture 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 28) .
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 stations to run in the Program watering cycle .
