11 Cleaning cycles (lev. A)

Each cleaning cycle can be divided into the repeating of 3 fundamental phasesTPF3FPT:

Phase A

-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 to the following table:
CycleName of the programComposition of the phases

SOFT CYCLE

CLEAN 1/SOFT

A+C

MEDIUM CYCLE

CLEAN 2/MEDIUM

2A+C

STRONG CYCLE

CLEAN 3/STRONG

4A+C

EXTRA–STRONG CYCLE

CLEAN 4/X-STRONG

6A+C

At the end of a cleaning cycle (at the end of the acoustic signal) the oven enter in a stand-by state, i.e. 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.)

12 Cycles, utilities, important parameters

Hot air cycle(Lev. A, B, C): Only the cavity heating elements/burners are working. The maximum temperature is 300 °C; if the set point is over 250 °C, the maximum working time that can be set is given by parameter dutM. If on a lev. A oven a humidity value is set, the lambda probe will control only the cavity flap.

Steam cycle(Lev.A, B): The maximum set point temperature is 100 °C (130 °C from firmware 2.6). Boiler heating elements/burners are controlled with the lambda probe (lev. A ovens) or with the by-pass probe (lev. B ovens) for a set point of 100 °C; for set point lower than 100 °C, the boiler is controlled with the cavity probe. If the set temperature is over 100 °C, also the cavity heating elements/burners are switched on.

Combi cycle(Lev.A, B, C): Boiler and cavity heating elements/burners are working (Lev. A, B). Cavity heating elements/burners are controlled with the cavity probe (Lev.A,B,C); boiler heating elements/burners are controlled by the lambda probe (lev. A ovens) or by the by-pass probe (lev. B ovens). In the Lev.C water is sprayed directly in the cavity fan with the umidifier. The maximum set point is 250 °C. From firmware 2.6, for a set point lower than 100 °C, to obtain the required steam the humidifier is used (not the boiler).

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 Δ) and not a cavity set-point. The cavity will be thermostatically controlled to have in any moment a cavity temperature that is Δ °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 the set point of the steam cycle.

Boiler automatic drain: The automatic boiler drain takes place each 15 minutes of working of the boiler heating elements/burners (parameter dbon in quarter of hour) 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.

3TP PT 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
