Calibration is failing.
Top Causes
● Debris is in the filter under nozzle obstructing water flow. FlexPipe was not flushed properly before installing head. Remove filter to clean/flush.
● Water pressure (PSI) at the head is too high and needs pressure regulation; could also be low and unable to run an Irrigreen system. We recommend installing a pressure regulating valve inline.
● Flow meter (if installed) is either incorrectly configured in System Setup or failing. Turn off the flow sensor and then on after calibration.
● Calibration fails due to another error that interferes with it (would be presented on the Zone screen).
● Head may not have a pressure sensor and needs manual calibration (enabled in System Setup).
Measure your pressure and ensure you have CONSTANT pressure between 40-80 PSI, unscrew the nozzle and remove the filter below and clean any debris out of filter. Re-calibrate.
