3 By-pass calibration (only for lev. B, not required on lev.C)
In order to calibrate the by-pass probe on lev. B ovens. Follow these steps (During the procedure, the word
“CAL” appears on the time display):
1) Switch on the oven
2) Enter in parameter programming and set parameters cort and OCA1 to 0
3) Exit from programming and switch on again the oven
4) Select a steam cycle (100 °C)
5) Select continuous time (indication “cont” on time display)
6) Press and hold down the left service buttons (A&B) and then press the START button (fig. 14); the
oven will give a long beep.
7) Release the three buttons and wait for the preheating of the boiler. Then wait for the stabilization of the
temperature reading by the by-pass probe (check at intervals the by-pass temperature pressing the
buttons A&B)
8) When the temperature has stabilized, press the three service buttons (A&B&C) together in order to
memorize the value (fig. 15); the oven will confirm the storing with a long beep
9) Allow the oven to work for several minutes in steam mode checking the oven cavity temperature, which
should stabilize at the water boiling point. If this reading is greater or less than the correct water boiling
point
