Watering Schedule (Days)

You can choose how often to water your lawn in one of three ways: 1) by Specific Days of the Week
(MO, TU, WE, etc.), 2) by Day Intervals (Every day, Every 2 days or Every 3 days), or 3) by a choice of
MO, WE and FR or TU, TH and SA. A schedule of Specific Days of the Week is especially useful if you
live in an area with local water restrictions that limit you to water, for example, on Mondays and Fridays
only.

Start Times

You can program your timer to start watering up to three times in one day. For example, you could set
watering Start Times of 3 a.m.,6 a.m., and 6 p.m. The system would then turn on the lowest numbered
station at 3 a.m., and would sequentially turn on the next station when that one has finished. Only one
station is watered at a time. The same cycle would repeat, beginning at the next scheduled Start
Time, in this example at 6 a.m.
Watering Duration
Each "station" can be scheduled to water for a different length of time, from 1 to 99 minutes. For exam-
ple, you might program Station 1 (your front lawn) to water for 5 minutes and program Station 2 (your
flower bed) to water for 10 minutes at each Start Time.
