Adjustable options:
+ How long you want to water (max. 60 minutes)
+ Every day, 2-day, 3-day, weekly,
+ How many times a day (up to 3 times)
+ At what time is to be irrigated (of the programming time is simply it expected the number of hours and then passes this on; Ex .: I program the clock by 12 clock, hire a delay of 6 hours, then the irrigation starts by 18 clock; the "drops" in the display goes always on, so you always know when it starts)
The clock can be retrofitted with a rain sensor, but we did not need, because our neighbors are determined off the clock during heavy rain :-)
Additional:
We have to irrigate 2 surfaces (front and back garden) and have connected a clutch below the clock. Goes smoothly, so that the more expensive dual clock can save yourself. However, then both valves at once.
From us a strong buy recommendation!
(PS: battery to keep 1 year, we will report!)
