The Output indicator will stay on solid right after powered up. This mean the

controller is heating up the kettle at maximum speed. Once the temperature is

getting close to the set point, the output indicator will start to flash at slower rate

or take a pause. It indicates the controller is trying to modulating the power to

hold the temperature stable.

For how to set up the timer in mashing mode, please read section 6.2.

5.3 Boiling Operation

When first powered up, make sure the controller is in the boiling mode: the

mashing mode indicator on the upper left corner is off and bottom display has a

"P" on the left. If not, change the control mode to boiling mode as discussed in

section 5.1 above. If you were using the controller in the boiling mode when

powered off last time, the controller will start in boiling mode.

The top LED displays the current temperature reading from the sensor. If

temperature sensor is not connected, it will show "orAL". The controller will not

turn on the heater if the sensor is not connected. The bottom LED displays the

boiling output in percentage of the power. For example, if you use a 5500

Watts heater, "P50" mean the heater is running at 50% of power, or 2750

Watts (5500 x 50% = 2750). The symbol "P" on the left is for making sure that

the display does not get confused with temperature setting of the mashing

mode. You can rotate the knob to adjust the output value. The new setting will

take effect automatically. There is no need to push the knob to confirm as the

temperature setting change in the mashing mode. For the first time use, while

the controller is still in the acceleration phase, you should set the boiling output

to a value below 60%. Once the controller finished the acceleration, it will

switch to this power level automatically. After getting familiar with your system,

you can set to a higher value that produce a rolling boil without boiling over.

When the controller is powered up, the output indicator will stay on solid. This

mean the controller is in the acceleration phase. Once the temperature rise

above the acceleration phase, the power output will be reduced to the value as

shown on the bottom display. The Output indicator will start to flash at slower

rate.

Note, when adjusting the boiling output setting while the controller is still in the

acceleration phase, the new setting will be shown on the bottom display.

However, it will not take effect until the acceleration phase is finished. If you want

to manually control the power output during the entire boiling process, set bAST

to zero (see section 6.3 for details).

For how to set up the boiling mode, please read section 6.3.

6. Control Parameters

Parameters are divided into four groups (figure 5): MASH for mashing control,

BOIL for boiling control, ALAM for alarm settings and SYST for system

configuration. The same type of parameter may have slightly different names

when used in different mode. For example, the timer setting in mashing mode is

called "t", while this parameter is called "bt" in the boiling mode.

To enter parameter setting mode, press and hold the knob for at least 5s. Then

you will see "GOTO" on the top display. Rotate the knob, you will see the bottom

display changes with three different names: MASH (for mashing parameters,

figure 7), BOIL (for boiling parameters, figure 8), ALAM (for alarm settings,

section 7) and SYST (for system settings, figure 6). The parameter values are

stored in the controller memory. All the settings remain unchanged if you power

it off.

Push the dial to enter the selected parameter group. Then top display shows the

current selected parameter name, and the bottom display shows its

value/options. Rotate the knob clockwise to increase the value, and rotate it

counter-clockwise to reduce the value. Faster rotating speed will change the

value rapidly. Once finished, press knob again to confirm and go to next

parameter. You can press the knob repeatedly to exit the setting quickly.

Note 1. Timer settings: tF, tdIr

tF. The timer function is controlled by a master parameter tF. When it is set to

ON, the timer function (for both mashing and boiling modes) is enabled. When

tF is set to OFF, the timer function is disabled.

tdIr: Timer direction parameter. Set it to up for timer counting up and dn for timer

counting down.

Note 2. 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, will make the controller display 0ºC.
