Main SpecificationsWorking voltage: DC3V2*AAA batteryQuiescent current consumption: less than 50uABattery life: Normal use is more than 3 monthsWorking temperature: +5 degrees ~ +60 degreesWorking water pressure: 0.02Mpa-0.8MpaFlow characteristics: 0.1Mpa)=16L/minInstructionsBefore using the electronic timer, you must:1 Put in 2 AAA batteries, and pay attention to aligning with the +/- signs. 2. Connect the electronic timer and faucet3. Set irrigation parameters a) Set the parameters required for automatic irrigation, FREQUENCY sets the irrigation interval time, RUNTIME sets the irrigation running time, and the irrigation start time is one interval after the current setting before working.Note: The interval must be greater than the irrigation running time, otherwise it is invalid. b) Under normal circumstances, the indicator light will flash once every 4 seconds, indicating that it is working normally. If the light flashes frequently, it indicates that the battery is low and the battery needs to be replaced in time.
