Note 5. Timer Function: t, tSP, EO
This timer function allows the controller to show the mashing 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 the t parameter for mashing mode. The unit is hour: minutes.
When timer function is enabled, the timer counting will be started by timer start
temperature, tSP. 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 knob 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, EO. 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 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 6. 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 7. 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
