There is a guy on the site that can probably tell you what is wrong with your controller and how to fix it.....Make a fake facebook profile and then delete it if you want to avoid contamination.
Check out the Brew Boss Electric Brewing Users Group on Facebook and join. The moderators have software to share and are very knowlegable about the system and particularly the controller versions.
I just started saving yeast a few months ago. I make a starter a day or two before each brew day. I use 3 quart jars of wort I made in a canner heated to 250 degrees in a pressure canner (to make sure no botulism spores are present). This means I don't have to make and boil wort for a starter...
I put my 20 gallon brewboss in the basement right next to my ferment chamber and kegerator. I got the condenser attachment and do not have an exhaust hood. The condenser works fine and I don't need a fan. Brewboss is out of business as of Jan 2022.....but it may just be a temporary closure...
The Brewboss website is still down and I believe Darin has gone out of business. I hope it is temporary and that he is OK and not ill. I have a 20 gallon brewboss system and belong to the "Brew-Boss Electric Brewing Brewing Group" Facebook Group. No one in that group has received a response...
