How often can it water?

Intervals run 1, 2, 3, 4, 6, 8, 12, 24, 48, 72 or 168 hours. Each cycle runs for 1, 3, 5, 10, 15, 20, 30, 60, 90 or 120 minutes.

Will it work from a water butt or tank?

It is listed for faucet, bucket or tank supply and rated 0–6.9 bar. A gravity tank gives low pressure, so check that your drippers open at that head.

Two AAA batteries. There is no mains lead, so mount it where you can reach the battery bay.

It has a 3/4-inch threaded connection, the common garden hose size. Check your tap or adapter before buying.

Yes. A start-delay function holds the schedule so you can set it up before a trip.

No. It has one outlet and one schedule, so two zones need two timers or a valve splitter with matched flow.
