4.) Fermenter (jacketed)
5.) Glycol fluid high and low
That leaves me with one station which might become a controller for the brew room running off it's own zone from the furnace.
I'm chilling my wort with the same system that will chill & warm my fermenter. I'll use glycol, a heater, and a chiller stripped from an old dehumidifier.
Now imagine I get bored with that and add another fermenter.
Oh I forgot:
6.) BK fluid level sensor
7.) Glycol fluid level sensor
Looks like I'm getting the additional controllers
Yes, the BCS is EASILY expandable, and extremely cheap to do so. Much cleaner and versatile than having separate PIDs and temp. controls. It is fun to set up your processes and just hit start and let it change temps., turn pumps on and off, all using different parameters to do so. You can run it manually from the PC, or you can use the full automation and let it handle the brew session for you. It is an amazing amount of control for $180!
