The pressure sensor inside of the sprinkler is failing either due to damage or inconsistent pressure. The sprinkler will continue to work, but real-time pressure adjustment mechanisms may be damaged.
Top Causes
● This error may throw unexpectedly, but if it persists, the internal pressure sensor is broken.
● Inconsistent pressure; CONSTANT pressure between 40-80 PSI is required
Ensure you have constant pressure. If you do not, regulation is required with a pressure regulating valve.
