To enter a Temperature Offset, carry out the following
steps:
1.
With the oven in Control Mode, press the Menu
Key twice. This will bypass the program edit
mode and bring up the Temperature Offset (“0
CAL”) display.
2.
To change the offset value, use the Up Arrow
Key (to increase) or Down Arrow Key (to
decrease).
3.
Press the Menu Key when the appropriate value
is shown in the Actual Display.
4.
Further menu items will begin to appear. Press
the Menu Key three additional times for the con-
troller to again display the Set and Actual tem-
peratures (control mode).
Once the Temperature Offset is changed, the actual dis-
play will reflect it. Allow the oven additional time to stabi-
lize. Compare the Actual Temperature display to the ref-
erence temperature. The displayed temperature is the
result of algebraically adding the actual temperature to
CAL value.
Thus, if a CAL value of 3 degrees is being used, a meas-
ured temperature of 50 degrees will be displayed as 53
degrees. Repeat steps 1 through 4 above if necessary.
Units (°C/°F)
The next menu item selects the desired temperature
units. The controller will display and program in units of
°C or °F. To determine the current units or to change the
current units follow the instructions below:
5.
With the oven in Control Mode, press the Menu
Key three times. This will bypass the program
edit and temperature offset calibration mode and
bring up the Units (“C C_F”) display.
6.
Use the Up or Down Arrow Key to change the
temperature units from °C to °F or vice versa.
Press the Menu Key when the desired units are
in the Actual Display.
