3.3 SSR output connection
The SSR control output of the DSPR400 provides a 12V DC signal that can
control up to 5 SSRs in parallel. Connect terminal 7 to the positive pole of the
SSR (terminal 3 on
Auber’s SSR
s). Connect terminal 6 to the negative pole of
the SSR (terminal 4 on the Auber SSRs). Please make sure the SSR is installed
on the heat sink with proper current rating.

Figure 3. Display modes of DSPR400
Display mode 1 (Normal operating mode):
When power is turned on, the top
display window shows the current sensor temperature reading. When timer is
activated, the top display will be switched between the current temperature and
current time alternately. In mashing mode, the bottom display will show your set
temperature. In distilling mode, the bottom display will show the current power
output in percentage (e.g. 50 for 50% power output). Please check section 5 for
how to adjust set temperature/power.
Display mode 2 (Time reset & Operation mode selection):
This display mode
allows you to reset the timer, or to switch between the mashing and distilling
operation mode.
A short press of the knob will enter this display mode.
1) The display will show “rSt” on top and “n” at the bottom. This is
the exit menu.
If you enter this mode by accident, you can press the knob again to exit this
display mode without changing anything.
2) Rotate the dial clockwise for one click will change the bottom display to “y”.
This menu is to reset the timer. Press the knob will reset the timer. It has two
purposes. A) If you want to use the timer as regular timer without correlation to
the temperature, you can start the timer at any time by the reset button. B) After
timer is timed up and process ended, you can restart the process again by the
reset button instead of power off the system and power it on again.
3) Rotate the knob with two clicks, the top display will change to “Mode” and
bottom will show “Mash*”. Rotate the knob again, the bot
tom display will change
to “
dStL
”.
These two menus are for setting the controller to either mashing control
or distilling control mode. Press the knob will set the controller to the operation
mode displayed. Please check section 5.1 for details.
Display mode 3 (Parameter settings):
Press down and hold the knob for 5
seconds to enter the display mode 3. Please check section 6 for details.

Operation
5.1 Operation mode selection
This controller offers two operation modes, mashing and distilling. When the
mashing mode is selected, the controller functions as a temperature controller.
It automatically adjusts the power output to hold the temperature at set point.
When distilling 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. The temperature resolution for mashing mode is 1 degree;
for distilling mode is 0.1 degree. Figure 4 shows how to select and switch
between these two modes.

Press the knob once. The display will show
“
rSt
”
. Rotate the knob with two clicks,
the top d
isplay will change to “Mode” and bottom will show “
Mash*
”.
Press the
knob will set the controller to mashing mode. When mashing mode is selected,
the yellow indicator on the top left corner of the panel will lit. This indicator will
be off if the distilling mode is selected.
Note*: due to the limitation of 7 segment LED display,
the letter “M”
is displayed as “
m
”.
5.2 Mashing Operation
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 mashing mode when powered off last time, the controller will
start in 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”
. The bottom LED displays your set temperature. To adjust its value, just
rotate the knob. Once the value of the setting is changed, a small dot on the right
bottom corner will be flashing. It tells you that the setting has been changed but
not confirmed. After you adjust the temperature to the desired number,
push the
knob to confirm the change
. After confirmation, the new setting will remain on
the display and the dot will be turned off. If you forgot to push the dial, the display
will return to original set temperature after 2 seconds. The set point will remain
unchanged. This mechanism is for preventing temperature set point change by
accident.
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
