How do I reset the DT-553 Trident Valve Controller after it enters lockout mode?

[LaWyatt]

If your DT-553 Trident Valve Controller has entered lockout mode, here's how to reset it and return to active operation. This typically happens if the center button is accidentally held too long. To reset the device, follow these steps: First, exit the lockout period by pressing and holding the Center Button for about 12 seconds. This action will reset the sensor, taking it out of the lockout and back to active mode. Once reset, the sensor will resume normal operation, checking for water every 15 seconds.
