Question about Gardena Irrigation Control Select

Thanks for the info!

Unfortunately, no. The display is actually the control unit for the whole thing. The battery is also inside. The only security is that if the display is stolen, the water will not run indefinitely because it is blocked.
However, I don't think anyone would steal just a display because that alone is useless. The best thing is to steal the whole thing and it takes the thief a few minutes to do this because the screw connection is relatively tight and cannot be removed from the tap very quickly. I hope that helps. I am very satisfied so far (this is my second summer) and it saves me a lot of water.
