The Gardena irrigation timer connects to the faucet and automatically controls the watering of your garden, such as the operation of a sprinkler or a drip irrigation system like the Gardena Micro-Drip-System. You can set watering times from five to 120 minutes. The irrigation timer starts watering immediately and automatically stops the water flow after the set time has elapsed. For continuous water extraction, it can also be set to permanent flow. A battery is not required for operation.
