Figure 16. DSPR320’s display when a program is ended. The OUT indicator is
on as the controller still tries to maintain the temperature at set-value.
Once the program has ended or stopped, pressing the RUN key won’t start the
program again. The user needs to reset the controller, by either going to
RST
in
the Quick Access Menu or cycle the power supply to the controller, before the
program can be started again.
5.9.
Use Relays to Assist the Brewing Process
The DSPR320 is equipped with two build-in relays, Relay 1 (labelled as AL1) and
Relay 2 (labelled as AL2). They are identical in terms of their capability and
specifications. There available Relay Mode settings are:
ALAM
,
BEEP
,
ALBE
,
RAMP
,
HEAT
,
COOL
,
STEP
, and
EXTN
. Please see section5.3 and 7.5 for more
details.
The functions of the relays can be divided into three main groups:
a)
Temperature alarms: ALAM and ALBE.
b)
Event
remainder:
BEEP.
c)
Program-section control: RAMP, HEAT, COOL, STEP, and EXTN.
For the first two groups, temperature alarms or event reminder, the main
application is to use the relay to drive an external buzzer.
With the functions in the third group, the controller can complete more complexed
home brewing automation tasks, such as turning on an additional heater during
the ramp-up section of certain steps, turning on the wort pump during all mashing
steps, or turning on a circulation pump for chiller during ramp-down sections when
wort needs to be cooled down. An example of how to use the replay to control
pumps are given in the section 10.1 of this manual.

Quick Access Menu
The Quick Access Menu has three functions as shown below.
RST
-- reset the program

Functions
(Rotate the knob to browse, press the knob to confirm the
selection.)
RST
N
No effect. Return to the normal operation mode.
Y
Reset the program, stop all outputs. The user
can start the program again by press down the
RUN key.
STEP
1 ~ 9
When a program is running, select a valid step
number to jump to the selected step.
Selecting the current step number has no
effect.
Selecting non-valid step number, i.e., a step
that doesn’t exist in the current program or a
step has been set to SKIP, has no effect.
MODE
MASH
Stop all output and switch to MASH mode if
current mode is BOIL.
No effect if current mode is MASH.
BOIL
Stop all output and switch to BOIL mode if
current mode is MASH.
No effect if current mode is BOIL.
To bring up the Quick Access Menu, simply press the knob shortly. When the
controller is not executing any program, i.e., the controller is at the END or the
STOP status, press the knob will bring up the
RST
function. If a program has been
started, press the knob will bring up the
STEP
function. The user can rotate the
knob to select the desired function. To confirm the selection, press the knob again.
The table below listed the details of each function in the Quick Access Menu.

Main Menu
Program settings and parameters are grouped into 6 submenus.
mPRG
– the program of Mash Mode.
bPRG
– the program of Boil Mode.
mSET
– settings for all mashing (temperature-control) steps.
bSET
– settings for all boiling (power-control) steps.
RELY
– settings for relay AL1 and AL2.
SYST
– system parameters.
To bring up the Main Menu, press down the knob for 3 seconds. Then the top
window will show “
GOTO
” (go-to) and the bottom window will show the first item
in the menu list, which is “
mPRG
” (mPRG). Turn the knob to find the correct sub-
menu, and then press down the know to select the item. The parameters in each
sub-menu are listed and explained below.
7.1.
mPRG – Mash Program
The user can enter or edit the Mash Program in this sub-menu. Only the settings
for Step 1 is listed and described in Table 11. Steps in the rest of the program are
identical to Step 1.

Note 1
. Set-value can be a percentage value or a temperature value,
corresponding to a boiling step or a mashing step respectively. The unit of set
temperatures is decided by the
C-F
setting in the
SYST
menu.
Note 2
. When the temperature has reached the timer-start-point of a step, the
controller will start the step-timer or execute the special command. The special
commands are explained below:
CONT
– Continue executing the Boil Program when the Mash Program is over.
END
– End the program.
HOLD
– Hold the program at the current step till the user press the RUN key.
SKIP
– Bypass this step.
However, the special command
SKIP
is an exception. If a step-timer is set to
SKIP
,
this step will be bypassed when running the program, and the step number will
become invalid in the current program. For example, in a 4-step mashing program,
if the user changes the
m2-t
to
SKIP
, the controller will only execute Step 1, 3, and
4, and the user can’t not jump to the Step 2 of this program.
The command
CONT
is only available in MASH program mode. To select
CONT
,
turn the knob counter-clockwise for a full turn when you see
END
. If the step-timer
is set to
END
or
CONT
, the controller won’t ask the user to enter settings for the
rest of steps. And so, the rest steps don’t exist to this particular program.
