want the buzzer to go off when the boiling is done, you will set nE = 1, that is
one event. But if you want to add another hop in the middle of boiling, this is
considered as the second event, the buzzer will go off when the second even
starts.
5.2) tdir , timer direction. This parameter appears only when nE = 1. It can be
set to “ dn ” (count-down), or “ up ” (count-up). When nE > 1, this parameter is
not available, and the timer will only count-down.

dn : count-down. The time duration is decided by t1 . At the end this single
event, the relay will pull in.

up : count-up. When tdir is set to up , event timer parameter t1 will be
disabled, and so the timer will not stop automatically nor activate the
relay. In this mode, the timer functions as two stopwatch timers by
continuously counting up, each display window shows one stopwatch
timer. Press the
START key will start or stop the timer in both top and
bottom display; press the RST key will reset both timers to zero; press the
MUT key will restart the timer in the top display window from zero, but it
won’t affect the timer in the bottom window. This function provides a time
reference for users during the mashing process if they want to take a
sample or do some tests of the wort.
5.3) Ad , alarm duration. It is the time duration that you want the relay contacts
to stay closed at the end of each event. The unit is in seconds. The alarm
durations of all events are the same.
Ad can be set from 0 to 200 seconds. The
number 0 and 200 are special cases. When Ad = 0, the timer will pause at the
end of each event and activate the relay. User need to press the START key to
resume the timer. When Ad = 200, the timer will continue to the next event,
while the relay contacts will close until user press the MUT key. When Ad is set
to any value between 1 and 199, the timer will continue run time while the relay
pulls in for a certain time duration decided by
Ad . For example, when Ad = 5,
the flashing buzzer connected to the output relay will be on for 5 seconds.

5.4) tx (i.e., t1, t2, t3, …, tn ), the time duration of each event, where x is the
event number, and n is decided by parameter nE . Time duration of an event,
tx , is the boiling time of an ingredient to be added to the boiling wort. t1 is the
first event timer which starts from the moment that the first ingredient is added
until the end of boiling,
t2 is the second event timer which starts when the
second ingredient is added until the end of boiling, and so on. Please refer to
Figure 3 for a schematic diagram of the event timers and the relay status. The
relay will pull in at the end of the event timer t1 and pull in at the beginning of
all other event timers ( t2 , t3 , and so on).
An event timer that starts later should be no longer then the event timers that
start earlier, i.e.,
t1 ≥ t2 ≥ t3 ≥ … ≥ tn . When an event timer is equal to its
prior event timer, this event timer will be ignored. For example, if you set t1 =
t2 , timer t2 will be ignored.
The top display window of JSL-73B will show the remaining time before the
next event timer starts; the bottom display window will show the remaining time
to the end of event timer
t1 , i.e., the end of all events.
6. How to Set Parameter nE and Ad
Press and hold SET key for 1 second, the top display will show nE . Use UP or
DOWN key to change its value shown in the bottom window to the desired
number of events. Press SET key again, the top display will show alarm
duration Ad . Use UP or DOWN key to change it to the desired value, then
press SET key again to save and exit.
7. How to Set Event Timer
Press SET key momentarily, display will show t1 , use UP and DOWN key to
adjust the timer to desired value and press SET key to confirm. Please note
that the settings will not be saved until SET key is pressed.
8. Application Examples
We have a buzzer connected to the timer relay and we want it to ring for 10
seconds when it’s time to add a new hop and when the entire boiling process
ends. The beer recipe requires Columbus hop being added at three different
time points for boiling:
1 oz. Columbus, boiling for 60 minutes.
2 oz. Columbus, boiling for 5 minutes.
2 oz. Columbus, boiling for 1 minute.
So the JSL-73B timer should be set like this:
1) Hold the SET key for 1 seconds, then set nE = 3, Ad = 10.
2) Short press SET key, then set t1 = 60, t2 = 5, and t3 = 1.
When we are ready to add hops, press the START key to start timer; then add
1 oz. Columbus hop in the hop bag and immerse the bag in the boiling wort.
After 55 min, the alarm buzzer rings, and the top window flashes “t2” to remind
us that the second event timer has started, and it’s time to add the 2 oz.
Columbus hops. We press the MUT key to temporarily mute the alarm. Then
add 2 oz. Columbus hops to the hop bag. After another 4 min, the alarm buzzer
rings again, and the top window flashes “t3”. We add another 2 oz. hops to the
hop bag. Finally, after another 1 min, the alarm rings and the top window of the
timer show “END”. We turn off the heater and are ready to cool the wort from
boiling temperature.
