I have a few pictures showing my 2 son-in-laws new 10 bbl commercial brewery at the western edge of Denver using 2 BCS-462 controllers in 2 control panels I built and installed for them this past week that I would like share, but am at a loss on how to post the pictures in this forum?

Their first brew session was last Sunday night, with the heat side controlling zoned Belimo steam valves fed from a 400 MBTU steam boiler for the HLT, MLT tanks and Boil Kettle and the cool side controlling 3 initial and 3 future glycol chiller cooled fermenters via zoned motorized ball valves. Boil was at 197 degrees due to Denver's elevation.
The chiller is currently set to circulate 30 gallons of glycol thru the system at 25 degrees, with motorized ball valves opening and closing via the fermenter temperature probe set points.

Both BCS's worked flawlessly, and I see that I only need tweak the temperature probe calculations due to some variation in probe versus actual temperatures in the tanks and kettle, maybe 3-5 degrees, but they are monitoring it with analog probes as to not under-overshoot temps. I came home back to Chicago, and will travel back to Denver once they do more brewing so I can tweak the temps with the BCS program.

I would think that their brewery is only a handful of commercial breweries using a BCS-462 which is more than adequate and user friendly for my kids to revise future programming versus using an AB MicroLogix or similar PLC. I also had them install the Brew Buddy IPhone app so they can monitor and change temps on their phones which works pretty well too!

Joe,
I am using the BCS460 to control a an oven used in the barley maling process I have a 300 btu/h steam boiler to heat the air for drying how do you control the boiler temp? I am trying to repalce the honeywell t-stat but am not having much luck. I think it uses a 24v signal to the boiler any info you have would be helpful. Thanks.

CD, We use 24VAC George Fischer motorized ball valves to open and close the 2" steam supply to the boil kettle. The 10" probe in the boil kettle inputs to the BCS, and through a simple temp loop statement in the BCS, sends the output signal to a solid state relay board to open and close a plug in relay with NO/NC contacts to open and close 24VAC to the valve. The steam boiler temp control is built in and separate to fire the burners to make the steam and isn't controlled by the BCS except on E-Stop to open its control circuit.
Hope that help, I can send you a PDF of the control drawing if you like..
Thanks,
Joe

Joe,
Thanks for the reply. I found out that to control the boiler with the BCS I need to use a 24VDC relay controlled from the BCS outputs. Pretty simple boiler is either on or off based on temp input. I am guessing this will not give me the +/- 5 deg temp control I need but will have to evaluate this once up and running. Thanks again.
