this step and current step number (e.g. P-1 for step 1) alternately.
2) When
MASH indicator is OFF
, the controller is in
boiling mode
. The top display will
show reading temperature, and it may also flash the total remaining time of timer
events alternately (see section 5.3.1). The bottom display will flash current output
power percentage (e.g. P50 for 50% power output) and current step number
alternately.
Display mode 2 (Step program reset & Operation mode selection):
This
display mode allows you to reset the timer (mashing and boiling modes), or to
switch between the mashing and boiling operation mode.
A short press of the knob will enter this display mode.

It functions the same if you press and hold the Key B for 5 seconds.
3) Rotate the knob with two clicks, the top display will change to “Mode” and
bottom will show “Mash”, which is for step ma
sh mode. Rotate the knob again,
the
bottom display will change to “Boil”, which is for boil mode.
These two menus
are for setting the controller to either step mashing control or boiling control mode.
Press the knob will set the controller to the operation mode displayed. Please

Operation
5.1 Operation mode selection
This controller offers two operation modes, step mashing and boiling. When the
step mashing mode is selected, the controller functions as a temperature
controller with steps. It automatically adjusts the power output to hold the
temperature at set point in that step. When boiling control mode is selected, the
controller functions as a power regulator. It allows the user to manually adjusting
the power to control the strength of the boil. Figure 4 shows how to select and
switch between these two modes.

5.2 Step Mashing Operation
5.2.1 Introduction
When first powered up, make sure the controller is in the mashing mode: The
yellow colored mashing mode indicator on the upper left corner should be on,
and the bottom display has no “P” on the left. If not, please change the control
mode to mashing mode as discussed in section 5.1 above. If you were using the
controller in the step mashing mode when powered off last time, the controller
will start in the step mashing mode.
After controller is powered up, the top LED displays the current temperature
reading from the sensor. If temperature sensor is not connected, it will show
“orAL”.
When the step mashing timer is triggered and counting down, the top
display will start to display the current temperature and the remaining time for
the current step alternately. The bottom LED displays your current set
temperature, and it may also flash current step status alternately
, including “run”,
“hold” and “stop”.
