1 Pcs Automatic Digital Pressure Controller 220v Water Pump Pressure Switch Controller with Automatic Protection Against Water Shortage

Use water shortage protection introduction: It is not controlled by the water shortage protection function for 3 minutes when it is turned on; that is, when it is turned on or reset, regardless of whether there is water or not, it will be used for 3 minutes, and then check after 3 minutes.
