Drain Interval: Controls how often the drain triggers (e.g., every 1 to 60 minutes).
Drain Duration: Controls how long the valve stays open per cycle (e.g., 1 to 10 seconds).
How to Adjust: Hold the SET button on the digital panel, scroll using the Up/Down arrows to the drain parameters (typically F55 / F56 or dI / dt), press SET to modify, adjust the values, and press SET again to save.
