If the valve is left on for any period of time, it can start filling the valve box with water. Das Paket enthält eine OpenSprinkler Regler (8 Zonen). This is the method that many prefer because most times when you open the manual bleed screw, it causes water to leak out into the valve box. To close the valve, turn the solenoid clockwise until the valve closes. The second way to open the valve is to grasp the solenoid (the black cylinder with the wires attached to it) and turn it approximately one-quarter turn counter-clockwise until the valve opens. The binding will automatically recover the device with the next status check (as usual). Depending on the device type this takes between 10 and 60 seconds.

OpenSprinkler hardware 1.4 or above has built-in RTC and backup battery, and the RTC option is turned on by default. This is because you can open a sprinkler valve without using the sprinkler timer. Opening the valve manually is very useful if you are checking out a sprinkler system. If your sprinkler timer has failed, or there is an issue with the wiring, it is still possible to turn on the sprinkler zone manually, by opening the valve with your hands.
