Simplified PID for BIAB
Hi guys,
There are some brilliant electrical control boxes out there for BIAB.
But I thought I wanted something simpler and smaller, one vessel brewery takes up a lot of space you know
So this is what I came up with….
- PID – Rex C100, Solid state relay, heat sink and probe from EBay R275
- Kitchen timer from EBay R38
- Enclosure from Communica R224
- Wires, plugs, switches, etc. I reckon around R200
- Piece if duct tape on the side (because I mounted the PID to close to the side) from Idiotville.com R100000000 in school fees.
Anyhow, the idea is;
- The Controller plugs into the wall and the urn plugs into the controller (on top).
- When the switch in in the 0 position the thing is not doing anything.
- When I switch it over to “Mash” the PID and the SSR does its thing, switching the urn on and off. Must say after I auto tuned it works brilliantly…… before auto tune… not so much
- When I switch it to “Boil” it cuts out the PID and goes straight full power to the urn.
- The kitchen timer is independently stuck on the outside, just giving a nice loud beeping when, it is time for me to do something. (I’m considering a different timer… smaller one… but I’m going to brew with it first to test the principal.)
- The clamp on top is to clamp it to the handle of the urn…
- Oh and the element light just lets me know there is power to the plug socket (urn).
Without further ado. Some pictures

Nice one, although I have no idea what's going on there
