On Line 2 of this Temperature Overview display screen, brew group 1, represented as BG1, is
reading ‘LOW’. This indicates that BG1 is below the temperature probe’s set range of measurement
(170F-270F / 76.6C-132.2C). If the BG1 heating element is on (element breaker in the left position)
for longer than 15 minutes, and the indicator continues to read ‘LOW’, refer to the error indicator on
line 4. Check Error Log Codes on page 26 if needed.
The lowest programmable temperature is 180F (82.2C) and the highest programmable temperature
is 220F (104.4C). The factory set temperature is 203F (95C). To change brew groups’ factory set
temperatures, refer to page 21.
The steam tank reading on line 4 will normally read the factory default setting of 250F(121.1C). To
change this temperature, see page 23.
The [OK] on the right hand side of line 4 is indicating that there are no errors being detected by the
control system. If, in place of the [OK] you find an error code (EX: AABB##), refer to the Error Log
codes on page 26.
