4-Zone Control The irrigation timer provides four independently programmable outlets. You can customize the start time, frequency and duration to meet the watering needs of your garden, lawn and swimming pool area. Sequential Logic Outlets run sequentially, one at a time. This prevents simultaneous starts, avoids water pressure loss and flow diversion, and keeps the output pressure stable for every zone. Rain Delay and Child Lock Rain delay can be set from 0 to 15 days to prevent overwatering during storms. A child lock mode can be activated by pressing the minus key for 5 seconds in automatic mode, protecting children and pets from triggering and reducing water waste. Smart Control The control logic uses frequency greater than duration to prevent overwatering that can saturate soil or cause root rot. A real-time countdown makes the watering plan clear and helps save water, supporting healthy plant moisture management.
