Note 1. Input offset: Pb
Pb

is used to set an input offset to compensate the error produced by the sensor

or input signal itself. For example, if the controller displays 2ºC when probe is in
ice/water mixture, setting Pb = -2.0, will make the controller display 0ºC. The
resolution for Pb is 0.1 ° C or ° F. It can be used to match its reading with other
higher resolution thermometers.

Note 2-1. Temperature unit setting: C-F
C-F

determines the temperature unit. It can be set to

(Celsius, ˚C) or

(Fahrenheit, ˚F).

Note 2-2. Power up settings: PuS
PuS

determines the SSR power output status when the controller is powered up

for both mashing and boiling modes. It can be set to

inst

(instant power-up) or

dely

(delayed power-up). If

PuS

is set to

dely

(by default), the bottom display

will flash “stop” when the controller is powered up. The output is disabled. Press

key A momentarily to start the program and enable the output. If

PuS

is set to

inst

, the program will be started when the controller is powered up. The output

is enabled at same time automatically.

Tip: After you switch between mashing and boiling mode, the program will be

stopped and bottom display will be flashing “stop”.

Note 3: Mashing timer starting temperature: tSP

This parameter is defined as the temperature difference between the measured
temperature (PV) and set temperature (SV), or deviation from the set point. Its
default value is 1 degree. It means when program finished current step and start
to heating at the maximum output power set by parameter mOUT (see note 5-2)
to reach the next step, the timer will not start to count until the temperature is
one degree below the set temperature of the next step. When the controller
finished current step, the controller will make two short beeps, and another two
short beeps after a second. Then, the controller will turn the heater to full power
to reach the next set point.

During the heating up process, the bottom display will flash between the step
number and set temperature alternately. The top display will display the current
temperature. When the reading temperature reaches one degree below the set
point, the controller will make three short beeps. Then the top display will start
to display the current temperature and

the remaining time for the current step

alternately. In other word, the timer for step mashing mode is countdown timer.

Note 4: Timer Function: tSP, EO

When the

program is “end” (please check section 5.2.2 for the difference

between “end” and “stop”)

, 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 for step

mashing mode, EO

. Set it to

for continue heating, set it to

OFF

to turn off

the output.

Note 5-1: 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 to remove this overshoot. Some users may
want to set oScr as negative number to purposely force a temperature overshoot,
which can reduce the temperature response delay between the HLT and MLT.
Please note oScr only affects the initial heating phase and also the transition
phase between steps. It has no effect if the reading temperature is already
settled at the current set temperature.

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.

Note 5-2: Mashing acceleration output power: mOUT

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 set temperature. The heating acceleration in mash mode is
controlled by mashing acceleration output power, mOUT. It is the power used
during initial heating phase and also the transition phase between steps. The
unit is in percent of power from 0% to 100%. It should be set to 100% unless you
want to manually adjust/reduce the power output during the initial heating phase.
(For example, if you have a very powerful heater with very small amount of liquid.)
