DOS shows 200mL

When you see 200mL every 30 minutes, that indicates the DOS outlet was in the ON position and not Auto. When the DOS is set to ON, is runs 8 min on and 22 min off and repeats and delivers 25ml a minute. (25*8=200)

I recommend not having the DOS outputs on the dashboard to prevent this from accidentally happening by moving the outputs to the unused tile bin.
