Brew-Boss® V2.06 Operation Manual
Note: The temperature can be defined as Fahrenheit or Celsius in the system parameters. It is
important that the temperatures entered in the steps below use the same temperature units as is defined
in the system parameters.
There are five (5) unique brew step types that allow you to define nearly any brew process or session.
Yes, only 5 step types allow you to define any brew session!
All 5 steps require the same parameters be entered, although some steps do not use all parameters. The
parameters corresponding to the columns in the spreadsheet are defined below.
Step Parameters
Step Type
– This is a number from 1 to 5 indicating the step type as defined below.
Prompt
– This is the text that will be displayed by the application to identify to the user what
step is being executed. It is also the prompt that will be verbally enunciated if the TTS option is
enabled for that step.
Note: The Prompt parameter cannot include any commas or
quotation marks!
Setpoint
– This is the temperature that the controller should heat to and/or maintain for the step
being defined. Enter zero if the heater is not required for the step being defined. Temperatures
must be in the same units as is defined in the system parameters.
Step Timer
– This is the time for this step and only applies to step type 4 as that is the only step
that incorporates a timer. The time should be entered in minutes. So 1.5 hours would be 90
minutes.
Boil Flag
– This parameter tells the controller that we are trying to boil the contents of the kettle
and is only used for step types 3 and 4. As the temperature that a wort will boil is dependent on
the specific gravity of the wort and the barometric pressure, the temperature that the wort will
boil is unknown.
Please note that water does not boil at 212F (100C) everywhere
! It only
boils at 212F (100C) at seal level on a standard pressure (29.92 in Hg) day! If you are at a
higher altitude or barometric pressure is low, your wort may boil at as low as 205F. It is
important that the controller knows the boil temperature to maintain, otherwise it would stay at
full power through the entire process and would not know when boiling commenced. This flag
set to 1 tells the controller that it should detect boiling, once detected, store the temperature
value where the wort boiled for the following steps and then proceed to the next step. It is best
to set the setpoint for any step where you set the Boil Flag to 1 to a value of 220F or 105C,
guaranteeing it reaches boil. Set this value to 0 when setpoints for mashing, etc. are set. This
flag tells the application that we are not trying to reach a specific setpoint, instead, we want it to
determine automatically what the boiling temperature is for the current conditions. The
application looks at the slope of the temperature rise curve and determines when that slope
levels off, which is the point where the temperature ceases to rise. That indicates that the kettle
