PROGRAMMING PROCEDURES (continued)
The factory settings
menu can only be
accessed by going into
the programming mode,
and pressing the 1st key
until "Machine Settings"
is displayed. Then press
and hold the 3rd and 6th
keys for three seconds
until "Factory Settings" is
displayed.
IMPORTANT:
Only qualified personnel
should make changes to
these Factory Settings.
NOTE:
The probe has been
factory calibrated. If a
controller board is
changed it is
recommended that the
previous calibration be
checked and entered on
the new board.
If this is not possible, or if
a new probe is used,
calibration should be
completed as at right:
Factory Settings Menu
• "InflRate:" - Inflow Rate. The inflow rate is factory set at 0.75 gallons
per minute. This value is required to calculate the water volume.
Generally the .75 setti ng will be quite accurate unless there i s
unusually low or high water pressure and volume, in which case the
Inflow Rate can be changed.
• "Calibration". To access the calibration program, press the 4th key
when "Calibration" is displayed. The probe is factory set and should
not need resetting, unless the controller board or probe is changed.
See Calibration Instructions below for detailed instructions.
• "TotaiVol:" - Total Volume. Total water volume is stored in the
Factory Settings menu as well as in the Service & Counters menu.
This total is not re-settable.
• "BrewCvcs:" - Brew Cycles. Total brew cycles is stored in the
Factory Settings menu as well as in the Service & Counters menu.
This total is not re-settable.
Calibration Instructions:
1. Turn brewer on and allow to heat to proper temperature, and the
heat light will go out.
2. Turn brewer off.
3. Access the programming mode, go to Factory Settings, go to
Calibration and press the 4th key to access calibration.
4. Using an accurate thermometer, determine the actual tank
temperature by measuring the temperature of the water coming out
of the faucet. It is important to run the water over the thermostat long
enough to get a proper reading. (An alternate method of establishing
water temperature is to remove the top cover of the brewer, then pull
out the level sensor. Insert the thermometer into the brewer. Allow
time for the thermometer temperature to stabilize.)
5. Once the actual tank temperature has been established, look at the
values on the screen. As an example, it may read "199F Corr. + 0"
This would indicate that the water temperature in the tank is 199ºF
with no correction (or calibration) of the probe. If the actual
temperature according to the thermostat was:
a. HIGHER by 3F (i.e. 202ºF in this example), press the 6th key 3
times until the screen reads as follows: "202F Corr. + 3".
b. LOWER by 3F (i.e. 196F in this example), press the 5th key 3
times until the screen reads as follows: "196F Corr. - 3".
6. Make sure the temperature on the left of the screen agrees with the
actual temperature of the water determined with the accurate
thermostat. Once this has been completed the SS2 will maintain the
calibrated setting.
7. Once calibrated, press the 3rd key to continue in the Factory
Settings menu, press the 1st key to return to Brew Settings menu, or
press the 2nd key to exit programming.
