If you want to use the timer as a regular timer without correlating to the

temperature setting, you can set the tSP below the ambient temperature (or

zero). The timer will start as soon as the regulator is powered up. You can use

the reset button (rSt) to reset the timer at any time.

Note 7: Alarm Function: ALH

EZboil has a built-in buzzer that can be programmed to beep when temperature

reaches the alarm set temperature, ALH. The alarm will generate four short

beeps every time the temperature rise from below ALH to higher than ALH. The

alarm function can be used to notify the operator when temperature is approach

the boil. The alarm function does not affect the heating or the time function, it

only provides the alarm sound.

Note 8: Temperature Control Tuning Parameters: oScr, AttE

The mashing control mode utilizes AI algorithm instead of the commonly used

PID or On/off control algorithm. The program is optimized for beer mashing. For

most system, there is no need to tune. It allows the system to heat up at

maximum speed, then hold the temperature stable with one-degree precision. If

you are not satisfied with the control result, these two parameters will help you

to fine tune the system. The overshot correction, oScr is for adjusting the

temperature overshot during the initial heat up. For example, if the temperature

overshot 3 degrees, set oScr = 3 should remove the overshoot. This parameter

has no effect after the temperature reach the set point. The attenuation

constant, AttE is for adjusting the temperature stability during mashing. The

value is from -2 to +2. The default value is 0. If the temperature fluctuates more

than one degree, user can increase the value. If the controller takes too much

time to correct the temperature drop, user can reduce the AttE to make the

system more responsive.

6.3 Boiling Parameters

For the easy of discussion, we divide the boiling mode into two phases, the initial

heating phase and boiling phase. During the initial heating phase, power

output is set high to accelerate the temperature rise. During the boiling phase,

the power output is lowered to prevent the boiling over. We name the output

setting for the boiling phase as "Boil Output" setting. Its value is always

displayed on the bottom LED display and can be adjusted by turning the knob.

The acceleration power output setting is not displayed at bottom display during

initial heating, because it rarely set to less than 100%.

Note 9: Acceleration heating function: bAST, bOUT

EZboil accelerates heating speed of the initial heating phase by running the

heater at high power, then reduce the power once the temperature is getting

close to the boil. The heating acceleration is controlled by two parameters,

Boiling acceleration set temperature, bAST and Boiling acceleration output

power, bOUT. The bAST set the temperature limit that below this temperature,

the controller will output at a power determined by the bOUT. When temperature

rise to the bAST, the output will automatically reduce to a lower level to prevent

a messy boiling over. The boiling over is caused by several factors including the

amount of foam on the surface and the power of the 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 10: Timer Function: bt, btSP, bEO

This timer function allows the controller to show the boiling time. It makes a

beeping sound when timed out and will display the process is ended. It can also

automatically shut off the controller's power output after time out. The time

duration is set by bt parameter for boiling mode. The unit is hour: minutes.

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

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

timer starts to count. 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 dial again will reset the timer (Figure 4)

After the timer starts, the top display will be switched between the current

temperature and current time alternately in every 6 seconds. 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.

When time counting ends, the controller will generate six long beeps. The top

display will switch between the current temperature and "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, bEO. Set it to

ON for continue heating, set it to OFF to turn off the output.

If you want to use the timer as a regular timer without correlating to the

temperature setting, you can set btSP below the ambient temperature (or just

zero). The timer will start as soon as the regulator is powered up. You can use

the reset button (rSt) to reset the timer at any time.

Note 11: Alarm Function: bALH

EZboil has a built-in buzzer that can be programmed to beep when temperature

reaches the alarm set temperature, bALH. The alarm will generate four short

beeps every time the temperature rise from below ALH to higher than ALH. The

alarm function can be used to notify the operator when temperature is

approaching the boil. The alarm function does not affect the heating or the time

function, it only provides the alarm sound.
