6 Adjusting temperature offset — Sub Set Point Menu
A. Follow the instructions in Step 4. to enter the Sub-level program. After Sub Set Point is displayed, pressing the temp.
button will access the following temperature features:
SCALE (F or C), HI TEMP, LOW TEMP, OFFSET (+ or -), MANUFACTURE MODE (Clear or Active).
•Do not change SCALE after it was set in step 4A, or settings will reset to default
values.
B. To adjust the temperature offset, access the OFFSET display in the Sub Set Point Menu. If cavity temperature is
above the set temperature, decrease (down button) the offset value. If cavity temperature is below the set
temperature, increase (up button) the offset value. The amount of offset needed should be the difference between
the cavity temp. and the set temp. Allow oven to reach set temp. and verify cavity temperature. Readjust offset as necessary.
C. HI TEMP and LOW TEMP are not normally changed unless requested by the customer. Accessing these displays and
pressing the up or down buttons will change each indicated setting accordingly.
D. MANUFACTURE MODE is not normally used, so this feature should be set to 'clear'.
