    What do you do for separating hops and hot break from the wert? I see you have a setup to allow
    for whirlpooling but is that not opposite if what you want with a center drain?

    bornholtz,Below is the wiring diagram for multiple DS18B20's. With the onewire sensors, you can
    run 3 wires and insert a sensor wherever along the length and then continue the wires to the

    Unfortunately the rPi only pushed 3 volts on the gpio pins and this relay needs 5V to trigger.
    You will need a 5v supply, probably the same driving you pi, and then a transistor that is
    turned on by t...

    Can that thing handle the 240V of a standard water heater element?Depends on the Wattage of
    your element. I have a 5500 Watt element @ 240 volts. Which is 5500 / 240 = 22.92 amps, over
    twice what that...

    Protto, I think I get what you are saying. I believe the difference is not to have the K_i term
    set to zero if you are far away (5 degrees in your example), I think you want to zero out the
    error term...

    Br3ttb, Unfortunately I'm not making use of a brewtroller. Your name came up as an expert in
    the field. I am currently driving all this using a Raspberry Pi, a ruby PID library and GPIO
    pins. I am tak...

    Alien, thanks for the contact, I'll see if Brett can tell me why this is a bad idea.Protto, I'm
    running a HERMS. Basically a HEX in my HLT, all electric at about 5500 Watts. I circulate
    through the co...

    So, when playing around with setpoints, I find that my error integral gets wound up to a large
    value in that it dominates everything else. While working out the problem, I have been running
    on PD mode...

    I have a dilemma and would like to go fishing for opinions.I am planning on putting together a
    keggle single-tier system this spring. I am lucky enough to have a SWMBO that gifted me two
    chugger pumps...
