Hi everyone. I need help..... I have a BCS-462 system. Most of the components came in a kit from eBrewSupply. I have their 3 wire, Male XLR connectors mounted in the panel, and Auber Instruments Tri-Clamp Liquid tight RTD Sensor, with their braided cable. Here's a link to the sensor...

Anyways, I called eBrewSupply and asked how to wire their 3 wire to the BCS. I really didn't the easiest answer, but more or less was told wire one red to the temp input, and the clear jacketed wire to ground. So I kept it consistent throughout wiring all 8 (fermenter, brite tank, glycol chiller, 3 vessel BH, plus room for 2 more fermenters Hook up my fancy tri-clamp sensors, and nothing. Do some digging and find out I need to change coefficient A,B, & C to match the non BCS sensors. Get that nailed down, and it got it working, sort of. Temp sensors GENERALLY read 20ish degrees high, and they fluctuate in 5.3* increments. So as for today, ambient temp was 85 or so, and they kept fluctuating between 104.3 and 109.6.
I swapped which wire was input, which was ground, swapped the reds, wired the reds together, no go. It keeps reading the same, and making the same big swings.
I put one in a 35* beer, and it read, you guessed it, 104.3.
I don't know what to do. Im beyond frustrated that this is holding me back from being able to brew... Any ideas on solution? And yes, I do have a ground wire going from the temp probe block of the BCS to the ground of its power source.
FYI, the coefficients I'm now using are:
A: 0.0369
B: -0.009117832
C: 0.0000895868
I even had an engineer verify them!
Thanks everyone
Caleb
