PROGRAMMING - PROCEDURES (continued)
Calibration
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. However this may not
always be possible, or if a new probe is used, calibration should
be completed as follows:
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 stablize.)
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:
HIGHER by 3ºF (i.e. 202ºF in this example), press the 6th key
3 times until the screen reads as follows: “202F Corr. + 3”.
LOWER by 3ºF (i.e. 196ºF 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
E-Max™ 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.
