One tap, one or several zones — and a battery that must not die · review
Eight programmes and fifteen frequencies on an LCD, a stated 0 to 8 bar range, and it works at no pressure at all.
The bottom line The only timer on this shelf that publishes a working pressure range — 0 to 8 bar — and states it runs at zero pressure, which is the difference between a timer that works on a rain butt and one that does not. Eight programmes, fifteen frequencies, an LCD showing state, time and battery, and a ¾" tap connection.
Eight watering programmes are available, with fifteen different frequencies selectable. Water pressure 0 to 8 bar, and the maker states the timer also runs well with no water pressure. It connects to any tap with a ¾ inch thread. An LCD display shows the operating state, the time and the battery condition, and the maker states the timer can be used with unclear water. It is waterproof, and the cover should be screwed on when used outdoors. A German manual is available as a PDF download.
0 to 8 bar. One listing out of five on this shelf publishes one, and it is the figure that decides whether the timer suits your supply.
The sentence beside it matters more: “with no water pressure the timer also runs well.”
A great many timer valves are pressure-assisted. They use the pressure of the supply to help the diaphragm seat, and on a gravity-fed water butt — which delivers about a tenth of a bar per metre of height — they either fail to open or fail to close.
A timer that works at zero pressure is the one that can sit on a barrel. That is a genuinely different product and almost nothing says which it is.
Stated, and unusual. Rainwater from a butt carries roof grit and organic matter, and a valve with a fine seat jams on it.
A timer described for unclear water is a timer with a coarser tolerance — which matters on exactly the application the pressure statement above suits.
More combinations than anything else on this shelf without an app.
What that costs is the interface: an LCD with a handful of buttons and a programming sequence you will look up every spring. The simplest timer here has fourteen lights and three cycles; this one has a screen and a manual.
A PDF download rather than a booklet in the box, stated in the first feature line. That is a real consideration on a device programmed once a year, and the maker says so.
An IP code. “Waterproof with the cover on” is a description; a code is a defined test, and on a device screwed to an outdoor tap for five months it is the specification that matters.
From 29 € to 32 €, that being the spread across the German, French, Italian and Spanish Amazon stores on the day of the survey.
Beyond the euro zone, the British Amazon store prices it in its own currency, which the spread above sets aside.
Nothing came back from the American Amazon store at all; the buy button there runs a search rather than opening an empty page.

Because many timer valves are pressure-assisted: they need mains pressure behind them to open or close properly. A gravity-fed water butt gives about a tenth of a bar per metre of height, which is not enough for those valves. A timer stated to work at zero pressure is the one that works on a barrel.
The pressure range it is built for. Eight bar is well above any domestic mains supply, so the upper figure is headroom rather than a limit you will meet; the lower one is the useful half.
The maker states it is waterproof and that the cover should be screwed on for outdoor use. That is a condition rather than a rating — there is no IP code here — and it means the cover is not optional.
A rain butt or a low-pressure line, where the timer has to open with almost nothing behind it
