The Mini-Clik can keep the irrigation system from starting or continuing after rainfall quantities of 1/8", 1/4", 1/2", or 3/4". To adjust it to the desired shutoff quantity, rotate the cap on the switch housing so that the pins are located in the proper slots. Do not forcibly twist the cap as this might break the pins. The time that it takes the Mini-Clik to reset for normal sprinkler operation after the rain has stopped is determined by weather conditions (wind, sunlight, humidity, etc.)
These conditions will determine how fast the hygroscopic discs dry out, and since the turf is also experiencing the same conditions, their respective drying rates will roughly parallel each other. So when the turf needs more water, the Mini-Clik is already reset to allow the sprinkler system to go at the next scheduled cycle. There is an adjustment capability on the Mini-Clik that will slow down the reset rate. By turning the “vent ring” to completely or partially cover the ventilation holes, the hygroscopic discs will dry more slowly. This adjustment can compensate for an “overly sunny” installation location, or peculiar soil conditions. The experience will best determine the ideal vent setting.
