To adjust steam settings, press the corresponding arrows to enter the new values. The steam
timer cannot be adjusted during bake operation.
You can adjust the time remaining with the arrows. The set time remains unchanged unless you
“0” out the remaining time.
If the door is opened at any time during the baking cycle, the TEMP, BAKE TIME, STEAM and
AIRFLOW DELAY settings will pause. Close the door to resume all functions.
The AIRFLOW DELAY option minimizes airflow at the beginning of the baking cycle. The heat
is off while the AIRFLOW DELAY is activated.
The oven monitors the heating system by comparing the current oven temperature to the set
temperature. If a problem arises in the heating system or there is a heating system failure, both
temperature displays will flash. If the problem continues, contact your authorized Hobart Bakery
Systems service agency.
BACK-UP CONTROL OPERATION (OPTIONAL)
If the main control panel ceases to function properly, baking can continue with the use of the Back-up
Controls, if equipped. The Back-up Controls are located behind the control door on rear wall of the
component panel.
To activate the Back-up Controls, flip the toggle switch to BACK-UP position. Temperature and steam
are now controlled by the thermostat dial and steam rocker switches, located on the back-up control
panel. Set the thermostat dial to the desired temperature. Once the oven has reached temperature,
steam can be injected by pressing and holding the steam rocker switch up to a maximum of 20 seconds.
More than this will cool down the oven and steamer excessively. Venting the oven must be done
manually by opening the door. The rack carrier will stop and lower when door is open. Close door after
venting is complete for rack carrier to lift and resume rotating.
SAFETY ALARM (STANDARD FEATURE, NO PARAMETER SETUP REQUIRED)
If the temperature at the probe is in the range of 570 - 600 degrees Fahrenheit for 10 seconds, the unit
will do the following:
1. Shut off all features.
2. Sound an alarm.
3. Flash the OVEN TEMP display (actual temperature is displayed).
4. Display the letters ‘SHdn’ in the BAKE TIMER display.
The oven will remain in the shutdown mode until the 120VAC power is removed from the controller.
