heater. The more foams there is, the easier it is to boil over. The vigorous the

boil is, the easy it is to boil over. To preventing the boiling over, operator should

skim the foam out and reduce the power as the temperature approaching the

boiling. Since the heater power and liquid volume varies between each

application, we suggest the bAST to be set at least 5 degree (Fahrenheit) below

the boiling point for the first time use. As you getting familiar with your system,

you can change this setting to higher or lower. The bOUT is the power used

during initial heating phase. The unit is in percent of power. It should be set to

100% unless you have a very powerful heater with very small amount of liquid.

The bOUT setting does not limit the power regulation range for boiling phase. If

you don't need to use this feature, set bAST to 0, so this controller will

work as a manual mode controller over the entire temperature range.

Note 8: Timer and event settings (boil mode): nE, bot1 ~ bot9

A timer event is defined as an action of adding an ingredient at a specific time

point during the wort boiling process. An event timer starts from the moment that

the ingredient is being added to the wort; it stops when the wort-boiling process

comes to an end. There can be multiple events during the wort-boiling process.

Each event should have a different starting time point, but they all end at the

same time, which is when the boiling process ends.

To start activate the timer event, you need to 1) change the timer status from

"stop" to "run" by pressing Key A momentarily. 2) the reading temperature must

be higher than bTSP (section 6.3, note 9). When the timer starts, the top display

will show the reading temperature and total the remaining time (before the end

of last event) alternately. The temperature and time display can be easily

differentiated with their appearance. The temperature reading has two or three

digits. For example, 212 degrees will be displayed as "212". The timer display

has four digits with flashing colon in the middle. For example, "01:20" for 1 hour

20 minutes. The bottom display will show the power output percentage and

current step number (e.g. P-1 for step 1) alternately.

Please see Figure 9 for a schematic diagram showing the relationship between

multiple events and the alarm relay status.

nE, total number of timer events. An event can be associated with an activity

such has adding hops or special ingredients. Each event has its own timer. nE

can be set to a number from 1 to 9. The built-in buzzer will be triggered at the

beginning of all events except the first event, and at the end of the entire boiling

process. So nE is equal to the total number of times you want the buzzer to ring.

You can also set the external relay synchronized with the built-in buzzer (section

6.4.2, note 12). For example, if you only add one hop at the very beginning of

the boiling process, and add another hop in the middle of boiling, which is

considered as the second event, you need to set nE = 2, and the buzzer will go

off when the second even starts.

Event timer: botX (i.e. bot1, bot2, bot3, ..., botX), the time duration of each

event, where X is the event number (1 ~ 9). X is decided by parameter nE. Time

duration of an event, botX, is the boiling time of an ingredient to be added to the

boiling wort. bot1 is the first event timer which starts from the moment that the

first ingredient is added until the end of boiling, bot2 is the second event timer

which starts when the second ingredient is added until the end of boiling, and so

on. The buzzer will be triggered at the beginning of all event timers (bot1,

bot2, ..., bot9). The buzzer will be also triggered when all the event timers are

ended.

An event timer that starts later should be no longer then the event timers that

start earlier, i.e., bot1 ≥ bot2 ≥ bot3 ≥ ...≥ botX. When an event timer is equal

to its prior event timer, this event timer will be ignored. For example, if you set

bot1 = bot2, timer bot2 will be ignored.

Example: If the first ingredient (bot1) needs 60 minutes, the second ingredient

(bot2) needs 10 minutes and third ingredient (bot3) needs 1 minutes of boil, you

set Bot1 = 1:00, Bot2 = 00:10, Bot3 = 00:01. Assuming the timer will start at 0

minute (add first ingredient here). 50th minute from the beginning, controller will

beep and let you add second ingredient. 59th minute from the beginning,

controller will beep again to remind you it is the time to add the third ingredient.

(nE = 3).

Note 9: Boiling mode timer function: tF, btSP, bEO

tF. The timer event function (for boil mode) is controlled by a master

parameter tF. When it is set to ON, the timer event function for boiling mode is

enabled. When tF is set to OFF, the timer function for boiling mode is disabled.

When timer function is enabled, the timer counting will be started by timer start

temperature, btSP. When reading temperature reaches timer start temperature,

the timer starts to count, and the controller will generate three short beeps. After

timer started counting, it will continue even if the temperature drops below this

start temperature. The timer can be reset to start from beginning again. To reset

the timer, press the knob momentarily, the display will show rSt on top and "n"

at the bottom, rotate the dial clockwise will change the bottom display to "y".

Press the knob again to reset the timer.

When time counting ends, the controller will generate eight long beeps. Both

displays will flash "End" alternately. After timer ends, the power output can be

configured either to continue heating, or shut off. It is controlled by the parameter

called ending options for boiling mode, bEO. Set it to ON for continue heating,

set it to OFF to turn off the output.
