    Thanks Dave. Would you mind sharing your PIDs and Servo settings? How do you set your TOP valve?
    My question was a bit more specific: Is it WORTH it? I'm afraid that i used to small tubes. I used 15mm tubes which may introduce too much anti pressure, and there is next to no natural air flow when the fan is off, so a damper may not add any value?!?
    I sure can just try it out, as it's build pretty fast, but still want to hear your opinions.
