12. Cleaning cycle

Each cleaning cycle can be divided into the repeating of 3 fundamental phases
Phase A
- Washing phase controlled through the parameters CLt1 (time of detergent injection) and CLt2 (time of
detergent + 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
-
detergent + 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
SOFT CYCLE
MEDIUM CYCLE
STRONG CYCLE
EXTRA–STRONG CYCLE
At the end of a cleaning cycle (at the end of the acoustic signal) the oven enter a stand-by state 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.
NB: To check the correct water installation, make sure the rotating wash arm does not turn below 100 rpm
(120 rpm max.)

9. Cycles, utilities, important parameters

Hot air cycle: Only the cavity heating elements/burners are working. The maximum temperature is 300 °C
(572ºF); if the set point is over 250 °C, the maximum working time that can be set is given by parameter
dutM. If a humidity value is set, the lambda probe will control only the cavity flap.
Steam cycle: The maximum set point temperature is 130 °C (266ºF). Boiler heating elements/burners are
controlled with the lambda probe for a set point of 100 °C (212ºF); for set point lower than 100 °C (212ºF),
the boiler is controlled with the cavity probe.
Combi cycle: Boiler and cavity heating elements/burners are working. Cavity heating elements/burners are
controlled with the cavity probe; boiler heating elements/burners are controlled by the lambda probe. The
maximum set point is 300ºC (572 ºF) for a maximum of 20 minutes. After that the oven drop automatically to
280ºC (536ºF)
Regeneration cycle: In this cycle boiler and cavity heating elements/burners work alternatively during the
first rising till the set point is reached. After the set point is reached, boiler and cavity works in parallel to
maintain temperature and humidity.
DELTA-COOKING cycle: This cooking cycle is used with the meat probe and hot air, steam or combi cycle.
For this cycle it is set a Delta temperature (let's call it D) and not a cavity set-point. The cavity will be
thermostatically controlled to have in any moment a cavity temperature that is D °C over the meat probe
temperature.
COOL: The cavity-cooling mode takes place with the fan running and water injection from the temperature of
180 °C (parameter trMA) to the temperature of 40 °C (parameter trMn). Passing from a cooking cycle to a
steam cycle, an automatic cooling phase will take place if the cavity temperature is over 3 °C from the set
point of the steam cycle.
Boiler automatic drain: The automatic boiler drain takes place each ¼ of hour of working of the boiler
heating elements/burners (parameter dbon) and if the water temperature is lower than 50 °C (parameter
tcdb). Then the boiler is automatically filled.
Board cooling: The cooling fan is activated starting from the temperature defined in parameter Sbc.

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
