Sixth meat probe temperature (lev. A)
Prb6
First cavity temperature
CEL1
Second cavity temperature
CEL2
First boiler probe

Second boiler probe
boL2
Bypass probe

HuM
KS contactor is activated for 15 s and the lambda probe is
fed and after a while the cavity humidity will be displayed
If one of the probes is detecting the same temperature of the ntc probe (PCB temperature), the
meanings are the following:
1) Probe in short circuit
2) Probe not connected (for example
Prb
on a lev. A oven)
3) Probe at the same temperature of the ntc probe
•
If the led “open door” is switched on in parameter programming mode, it means that the safety level
probe of the boiler is detecting water
•
If the led “scale alarm” is switched on in parameter programming mode, it means that the working level
probe of the boiler is detecting water
10. Selection of the language for the recipe menu (lev. A)
Starting from firmware release 2.30 on lev. A ovens it is possible to select a language for the menu of the
recipes. To select the language, set parameter
LanG
to the correct value for the desired language (see the
relevant parameter list).
11. Cleaning cycle (lev. A ovens)
Each cleaning cycle can be divided into the repeating of 3 fundamental phases
3
:
Phase A
- Washing phase controlled through the parameters
CLt1
(time of detergent injection) and
CLt2
(time of
det water injection)
Phase B
(like Phase A but with the final sub phase with 20 seconds of water)
-
Washing phase controlled through the parameters
CLt1
(time of detergent injection) and
CLt2
(time of
det water injection)
Phase C
- Rinsing and drying phase controlled through the parameters
CLt3
(time of rinse aid injection) and
CLt4
(time of water injection)
The cleaning cycles are composed according the following table:
Cycle
Name of the program
Composition of the phases
SOFT CYCLE
CLEAN 1/SOFT
A+C
MEDIUM CYCLE
CLEAN 2/MEDIUM
2A+C
STRONG CYCLE
CLEAN 3/STRONG
2A+2B+C
EXTRA–STRONG CYCLE
CLEAN 4/X-STRONG
2A+4B+C
At the end of a cleaning cycle (at the end of the acoustic signal) the oven enter a stand-by state (from
firmware 2.40), i.e. the boiler heating elements are not fed, the user interface shows only the time and the
ON-OFF button led is the only lit up led. The exit from this stand-by state takes place with an action from the
user: pressing of a button of the user interface or opening the oven door.

At the beginning of each phase the cavity is brought at a certain temperature with a COOLING phase without water or with an hot air
cycle
