I would check batteries I have never had a problem I love the raindrip water timer
I have used a lot of different hose-bib timers in a commercial setting... this is the only model that has held up. All the rest have either started leaking water into the mechanism itself, or have simply failed to work after just a few weeks. I have over a dozen of these in use, and none have failed me over several years of use. (Nine months of use each year) This model can indeed be set to irrigate twice a day, (and for three minutes to two hours each time), but the start times will be twelve hours apart. (It can be set to come on once every three days, two days, once a day, or 2, 3, 4, 8, 12, or 24 times a day, each with an equal time span between each watering during that 24 hr day)
It is designed to default to a closed setting.
No, I have 125 psi charging mine.
Here is a link to the Timer Guide. http://raindrip.com/images/timer-install-guide.pdf
It is recommended that the batteries be changed annually. Mine are set to come on twice a day... I use it nine months a year, and the batteries have never failed me during the year.
Perfectly water proof.
