Special Note
1)
This parameter
rLP
imposes a hard constraint on at which steps the relay
function is enabled. However, whether the relay will be actually activated
depends on the relay mode (
rL
) setting and whether the activating condition is
met. This parameter applies to all relay modes.
2)
The “step” here refers to the “extended step”, which includes a step and the
ramp section prior to the step. Please see section 5.4.
Note 5
.
LAT
, latching mode, determines how should a relay returns back to its
deactivated status once it is activated. It only affects the relay if the Relay Mode
rL
is set to
ALAM
or
ALBE
. This parameter can be set to
N
(normal/non-
latching) or to
PUL
(pulsing).
When
LAT
=
N
(normal), the relay will be activated when the alarm condition is
met, and it will be deactivated when as the alarm condition is removed. When
LAT
=
PUL
(pulsing), once the alarm is triggered, the replay will stay in the activated
status for a pulse duration that is defined by parameter
AP
(please see Note 10 in
this section). This function is useful in situations where the user only needs to
energize the buzzer for a short period of time once the alarm is triggered.
Note 6
.
SIL
, alarm-silence/suppression, determines whether to suppress the
Absolute Low Alarm (
AL
) when the controller just starts running the program and
the water or wort temperature is still lower than the Absolute Low Alarm (
AL
). By
default,
SIL
is set to OFF. If
SIL
= ON, controller will suppress the relay action at
the very first time that the Absolute Low Alarm (
AL
) is triggered. If the Absolute
Low Alarm (
AL
) is turned off, the
SIL
setting has no effect on the relay actions.
Note 7
.
AH
(Absolute High Alarm) and
AL
(Absolute Low Alarm), defines the
high and low temperature alarms that applies to the entire control process from
the beginning of a program till the end of a program. When the temperature is
higher than
AH
, the alarm relay will be activated; it will be deactivated when
temperature drops below (
AH
-
HY
). Similarly, when the temperature is lower
than
AL
, the alarm relay will be activated; and it will be deactivated when the
temperature rises above (
AL
+
HY
). However, please note, absolute alarms
won’t work in situations where a program is ended or stopped.

Note 8. dH
(Deviation High Alarm) and
dL
(Deviation Low Alarm), defines the
how much temperature deviation from the set temperature (
SV
) is allowed before
the alarm is triggered. For mashing steps, the set values are temperatures. When
the temperature is higher than (
dH + SV
), the alarm relay will be activated; it will
be deactivated when temperature drops below (
dH
+
SV
-
HY
). Similarly, when
the temperature is lower than (
SV
-
dL
), the alarm relay will be activated; it will be
deactivated when the temperature rises above (

-

+
HY
).

Figure 18. Deviation alarms.
Special Note
: deviation alarms only applies to mashing steps and only when the
step-timer has started; it doesn’t apply to the ramp sections of a program nor
applies to boil-steps.
Note 9. HY
, hysteresis/differential band, determines the difference between the
temperatures of activating and deactivating an alarm. By default,
HY
= 1.
Note 10
.
AP
, alarm pulsing duration, determines the time duration of which a
relay should stay activated if a relay’s
LAT
is set to
PUL
. The unit is in second,
and the range is from 1 to 100 seconds.

Note 1
.
Pb
, probe offset.
Pb
is a value added to the probe reading to
compensate the error produced by the sensor or input signal itself. Normally it
should be left at zero. For example, if the controller reads 33ºF from a probe
immersed in well prepared ice bath which is supposed to be 32°F. Set
Pb
= -1.0
and so the controller should show 32°F. The resolution of Pb is 0.1°F or °C,
which enable the user to calibrate the probe reading with high resolution
thermometers.
Note 2
.
C-F
, temperature unit, can be set to °F (Fahrenheit) or °C (Celsius).
Changing the temperature unit only affects the probe reading. The numerical
values of set temperatures and other temperature related settings will not be
changed or converted.
Note 3
.
PUS
, power-up setting, determines how should the controller start the
program and send out control signal. When
PUS
=
INST
, controller starts
executing its program once it is powered up.
PUS
=
DELY
, program won’t be
executed until the user press the RUN key to start the program.
Note 4
.
ART
, auto-return time, determines how long should be the controller
wait, if no key is pressed, before it returns from the menu list to the normal
operation mode. The unit is in seconds, and the default value is 30 seconds.
Note 5
.
KNOB
, knob operation, determines whether the controller allows the
user to change the set-value and the step-timer using the knob from the main
interface while the program is running. When
KNOB
= Y, this operation is
allowed. When
KNOB
= N, this operation is not allowed.
