10) 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
1
, a corrective value can be stored in the parameter OCA1.
11) Set parameter cort to 1.
12) Set the altitude above sea level of the site on parameter SEAL
4. Lambda probe calibration (only for lev. A ovens)
The calibration of the lambda probe is necessary (from firmware 2.6) for the right working of the oven in
case of cycle with set point under 100 °C. With this procedure we have to find the point of 0% of humidity.
The procedure is done in a way similar to the by-pass calibration. These are the steps:
1) Set an hot air cycle, 150 °C, time over 15 minutes, open flap;
2) Start the cycle pressing together the left and middle service buttons and the START button. The
oven will give a long beep;
3) Wait around 10-15 minutes to dry completely the cavity;
4) Close the flap and wait around 20 seconds to stabilize the humidity inside the cavity;
5) To store the value press together the 3 service buttons. The oven will confirm with a long beep.
6) Stop the cycle with the START button.
This calibration is very important and has to be done with care. If the dry point (0% of humidity) is not
correctly stored, the reading of the relative humidity could be overestimated or underestimated.
