“ TEMP ” indicates the control cabinet temperature has
exceeded 155°F (68°C) causing the unit to shut down. If this
occurs, the unit must be turned off for at least 20 minutes so
it can cool off and reset. If this condition occurs again, con-
tact your maintenance person or Authorized Service Agency.
The Control Board monitors the control cabinet ambient tem-
perature and records the highest temperature. Your
service technician could find such information very useful
when troubleshooting the unit.
To determine the control cabinet’s highest temerature since
the last reset:
1. Turn the unit off.
2. Turn the unit back on while pressing both the UP and
DOWN ARROW buttons at the same time.
3. Read the highest control cabinet temperature shown
on the display and release the arrow buttons.
4. Turn the unit off again to preserve this record.
To clear/reset this record, press both the UP and DOWN
ARROW buttons simultaneously (before turning the unit off)
and the display will show 33°F — indicating that record has
been cleared
—
and then turn the unit off.
TEMP
“ LOW ” will be displayed until the Generator temperature
exceeds 250°F (121°C).
LOW
“
ERR
” will be displayed if there is a programming parameters
error. If this message appears, you will have to clear the
current parameters. To clear the unit’s current programming
and reset the unit to its factory settings:
1. Turn the unit off.
2. Press and hold the
SINGLE SHOT and PROGRAM
buttons simultaneously and continue to hold them while
turning the unit back on until you hear the beep stop.
3. Check the display:
• If the Display shows “ERR” again, repeat steps 1
through 2. If “ERR” still appears on the display,
contact your maintenance person or Authorized
Service Agency.
• If the Display appears normal, try a single shot
before attempting to reprogram the unit.
Review the Programming section of this manual and then
program the Menu Channel buttons according to your
cooking requirements.
