these Factory Settings.
NOTE:
The probe has been
factory calibrated. If a
contr oller board is
changed it is
r ecom me nd ed t ha t t he
previous calibration be
checked and entered on
the new bo ar d.
If thi s is not possi bl e, or if
a new probe is used,
cali brati on should be
completed as at right:
Factory Settings Menu
• "Infl Rate:" - Inflow Rate. The inflow rate i s factory set at 0.75 gall ons

• "Calibration". To access the calibration program, press the 4th key
when "Calibration" is displayed. The probe i s factory set and should
not ne ed resett i ng, un less the co ntr o l ler board or pr obe is chang ed .
See Calibration Instructions below for detailed i nstructions.

T his to tal is not re -settable.
Calibration Ins tructions:
1. Turn brewer on and allow to heat to proper temperature, and the
heat light will go out.
2. Turn brew er off .
3. Access the programming mode, go to Factory Settings, go to
Calibration and press the 4th key to access calibrati on.
4. Usi ng an accurate thermometer, determine the actual tank
tem per a tur e by me asuring th e tem per ature of t he water comin g out
of the faucet. It is important to run the water over the thermostat long
enough to get a proper reading. (An alternate m ethod of establishing
water temperature i s to remove the top cover of the brewer, then pull
out the level sensor. Insert the thermometer into the brewer. Allow
tim e for the thermometer temperature to stabilize.)
5. Once the actual tank temperature has been established, look at the
values on the screen. As an exampl e, it may read "199F Corr. + 0"
This woul d indicate that the water temperature in the tank is 199ºF
with no correcti on (or calibration) of the probe. If the actual
temperature according to the thermostat was:
a. HIGHER by 3F (i.e. 202ºF i n thi s exam ple), press the 6th key 3
tim es until the screen reads as follows: "202F Corr. + 3".
b. LOWER by 3F (i.e. 196F i n this exampl e), press the 5th key 3
tim es until the screen reads as follows: "196F Corr. - 3".
6. Make sure the temperature on the left of the screen agrees with the
actua l tempe ratu re of the wate r determ ined with the accurate
thermostat. Once this has been completed the SS2 wi ll maintain the

PROGRAMMING PROCED URES (cont inued )
PULSE BREW PRE-INFUSION CAPABILITY
BYPASS SYSTEM
Applications:
1. Pre-infuse (or Pre-soak) the Bed of Coffee or Tea.
The brew valve can be opened for a -short peri od of time to
allow the bed of coffee or tea to be pre-i nfused. After a delay
while the pre-soaking is taking place, the brew valve can be
opened to start and complete the brew.
2. Extend Contact Time With the Coffee.
The brew valve can be programm ed to "pulse" by opening
and closing for programm ed periods during the brew. This
ca pability will allo w for longer contact with the coffee or tea if
higher extraction rates are required.
3. Prevent Brew Chamber Overflow.
The pulse feature allows the delivery time of the water to be
extended. Over flow pr ob le ms can als o be ex p er ie nced if
particul arly fi ne grind coffee i s used. The SS2 can be
programmed to extend the delivery of the water over a longer
period of time, thus preventing any overflow problems.
Access the Pulse System:
1. Se lect th e Brew Vo lu me that will be us in g t h e "pu lse" br ew
system. (i.e. Brew Volume 1, 2, 3 etc.)
2. With the selected volume on the screen (e.g.: BrewVoI1:),
chan ge v ol um e if necessar y (must not be "0 ") and pr ess t he
4th ke y (whi le in to tal valve time displa y) to go to the Pulse
Programming options (as opposed to pressi ng the 3rd key
which would bypass Pulse Programming).
3. T he fi rst three menu item s below wi ll appear in this order.
a. InitVlv Time: Initial Val ve Time (seconds) to open before
pulse cycle(s) begin.
b. Pulse Delay: Number of seconds valve i s closed
beginning pulse cycle(s).
c. Pulse Valve On: Number of second's valve is open
during pulse cycle(s).
d. Total Valve: Total num ber of seconds valve i s to be open
(pulse + initial). This determines your total volume out of
brew chamber, which must be set i f total vol ume changes
from fa ctory se ttings.
e. D r ip O ut T im e: T ime after va lve is closed be for e all wat er
drips through brew cham ber as brewed product and the
brew is complete.
Pre-infusi on is used to pre-wet
the bed of grounds or tea leaves
prior to the actual brew. T his may
be used to improve the brew
quality in certain situatons.
Pul si ng the delivery of brew water
exten d s the time th e water is i n
contact wi th the coffee grounds or
tea leaves. This can be adjusted
to optimi ze extraction rates.
Pul si ng the delivery of brew water
a llows more time for the wat er to
drip out of the brew chamber.
This can be set to prevent brew
chamber overfl ow when very fine
grind coffee i s used.
Bypass System delivers a portion
of th e total volume of wa te r
directly to the container. This i s
used in situations where del i very
of all water through the coffee
grounds or tea leaves would
result in too strong a product.

Pulse Feature Operation:
When the pulse brew begins, the brew valve will be opened for
the number of seconds programmed for "Initial Valve Ti me"
(Ini t Vlv Time). The valve will then clo se f or the num be r of
seconds in "Pulse Delay", then open for the number of seconds
i n "Pulse Valve On". The pulse cycle (Pulse Delay plus Pulse
Valve ) will be repeated con tinuously un til the brew valv e has
been opened for the time program med as "Total Val ve ".
Water Outfl o w (Deliv ery) Rate s:
T he ou tflo w rate of wa te r from the sprayhea d is required to
calculate valve time for different volumes. Sprayhead outflow
rates are based on the standard 64-ounce coffee brew requi ring
approximately 117 seconds of the brew valve being open. T his is
an outflow rate of approximately .50 ounces per second.
To calculate Total Valve time, the total ounces required should be
divi ded by .50 oz/second. Each brewer may have a slightly
different flow rate based on whether the brewer is level, scale
bui ld up on lines, etc. Minor adjustments m ay be required to get
precise volume.
Bypass Valve System:
Access the Bypass System from the "Brew Setti ngs" menu,
"Total Valve" sub-menu (sam e as Pulse Brew).
1. Bypass delay: Number of seconds after brew starts valve will
open.
2. Bypass Valve Tim e: Num ber of seconds valve i s on.

F A UL T D ETECTI ON
Faul t De tection:
Software-level fault detection is performed usi ng the temperature
probe, and the water level sensor.
In the event of a fault, solenoid valves are closed, the heater
tri ac is turned off, all LEDs fl ash, an error message is displayed
and the system halts by entering Error Mode.
The system can be reset by removing the power to the system or
by holdi ng down the 8th (Left Stop Brew key) for 2 seconds.
These errors are moni tored at all times:
1. Probe/Heater Error
If the temperature of the water does not i ncrease 4ºF in 4
minutes with the heater on, then ei ther there i s a probe and/
or heating element failure, or the water is boiling. In either
case, the system halts with a "probe/heater err" message.
2. M aximum Temperature Reached
If the temperature exceeds a l imit, then an overheat error
message is produced. This error can occur if the heater triac
fails "on". The maximum temperature shoul d be set in the
menu system as to prevent boil ing.
3. Water Level Sensor Timeout
If the inflow valve is opened and water is not detected within
30 minutes, the message no water sensed is produced.
This can be caused by level sensor failure or water i nflow
valve failure . After the tank is filled to full capaci ty, the time
limi t varies with the state of the outflow val ves:
a. Two sides brewing: 5 minutes
b. One side brewing: 3 minutes
c. No brewi ng being performed: 1 minute
4. Internal Component Fault
The controll er is al so capable of verifying the proper
functioning of internal components:
a. "Keypad locked" message i ndicates that a key has been
hel d down for an extended amount of time. This i s
perceived as a faul t in the keypad controller.
b. "Valve faul t" message indicates that the val ves are not
responding properly.
Fault detectio n is perfo r m ed at
all tim e s, excep t in Off mode.
IMPORTANT:
The boiling temperature of
water will vary with al titude.
