NOTES:
* All single element controllers are capable of running multi-vessel systems if you are willing to swap element and temp probe cables when kicking off the boil.
** This feature uses a mechanical switch or relay to completely disconnect both hot legs of the element output so no voltage is present at the element or cable when OFF.
*** In the case of an electrical fault, this breaker should trip but it is not a replacement for the use of a GFCI protecting breaker in your main electrical panel.
^ Boil Acceleration is a feature that avoids boil-overs even when unattended but still allows the ramp up to boil temps to happen at full 100% element output.
^^ The Brew Buddy I supports two connected elements at the same time, but a panel selector switch determines which one will receive power at any given time. The Brew Buddy II supports two simulataneous elements but requires 50amp input.
