A1
Memory Location Buttons
Each button is a quick memory location where a program or wash
cycle can be stored by long press. To start the stored program,
press slightly.
Table 1: Panel Control description.
The LCD display is a very important part of the oven interface. The meaning and
usefulness of each icon is explained below:
Figure 4: LCD screen.
Icon
Function
This icon shows the selected cooking program, the digits on the left show
the program number; 1,2,... 99. The flashing PROG icon indicates that the
program is being edited and shows the two digits. By contrast, if the digits
are held steady and flashing, the program is being selected and it is possible
to navigate through the programs using the rotary knob.
This icon shows the firing phases of the programs. The first digit shows the
phase in which you are while the second digit shows the total number of
phases. Like the previous icon, if the STEP icon flashes, the firing phase
indicated in the first digit is being configured. However, if the digits are
flashing and the icon remains fixed, it is possible to navigate through the
different phases using the rotary knob.
This icon shows the 4 self-cleaning programs of the oven. The digit shows
the program number and blinking indicates that you can navigate through the
various cleaning programs with the rotary knob.
If the oven does not have self-cleaning, there is only one manual program
with cleaning assistance.
This icon shows that the rinse program of the oven chamber has been
selected.
If the oven is not self-cleaning, there is no such function.
There are two displays of this type. Both display temperature and time
values as well as other keywords that define the oven's behaviour. In normal
operating mode, the display on the left of the control indicates the
temperature set for cooking. The one on the right shows the remaining time
if a time firing has been chosen or the core probe temperature if a core

10
temperature firing has been chosen.
This icon indicates that cooking has started.
This icon indicates that an automatic or assisted manual cleaning cycle is
being performed.
This icon marks the setting mode. Allows you to display and edit the oven
configuration parameters.
This icon illuminates whenever the TSC, Thermal Stability Control, is
activated.
When this icon illuminates, the oven is in ECO mode. In this mode the oven
consumes a fraction of its usual power. The ECO mode is automatically
activated in situations where the oven requires little power, and
automatically deactivated in situations where full power is required.
This icon flashes when the oven does not detect any connected probe and
needs it to start or continue a firing cycle. If the probe is connected, the icon
will remain fixed when, without being in the firing process, the desired core
temperature is lower than the temperature read by the probe.
This icon lights up during the assisted manual cleaning process of the
camera. When this icon is lit and blinking, it indicates that liquid with
detergent must be introduced into the interior of the camera using a spray
gun.
This icon lights up during the manual cleaning process assisted by the
camera after the previous one. When this icon turns on and blinks, it
indicates that the shower faucet must be inserted into the interior of the
camera and rinsed.
This is the error icon. Lights up when an error occurs and is accompanied by
the error number on the right display.
This is the alarm icon. Lights up when an alarm occurs and is accompanied
by the alarm number on the right display.
This icon indicates if the door is open. The icon illuminates whenever the
oven door is not closed regardless of the operating moment.

11
This icon indicates that the oven needs to be charged to continue the firing
cycle. When it turns on and flashes, the door must be opened and charged to
continue.
If a self-cleaning process is being performed, the icon indicates that the
detergent tablet must be inserted into the camera.
This icon indicates that a cooking process may be finished. When it comes
on and blinks, open the door and unload the trays with the cooked products.
This icon is used to indicate humidity inside the camera.
The DRYOUT icon is associated with the red icons at the top of the graph.
These icons indicate the degree of moisture removal in the camera. There
are five levels and grow from left to right illuminating one more bar each
time a level is raised.
Similarly, the SMARTCLIMA icon and blue bars indicate the degree of steam
generation. In this case they increase from right to left to maintain the same
representation model.
Table 2: Description of LCD display icons.
2.1.1 Switching on the equipment
The equipment is turned on or off using a switch on the control panel to the left of the
panel.
In order to protect the oven from possible overheating, some protective
elements may work even if the oven is switched off. When the oven is at a
safe temperature, they will turn off automatically.
2.1.2 Rotary knob LED indicator
The rotary knob has an illuminated circle indicating the operating status of the oven.
This indicator changes colour depending on the state of the oven, allowing the user to
check easily and quickly and even while at a certain distance from the oven if a process
has been completed, etc.
The possible colours of the indicator and their meaning are given below:
Mode
Temperature
This colour indicates that the oven is not cooking or
cleaning. The oven's not working.

12
This colour indicates that you are cooking.
This colour indicates that a cleaning or rinsing process
is in progress.
This colour has three different meanings.
If the oven is cooking or washing, it indicates that the
cooking is about to end: if there is 1 minute left to finish
a time cooking or cleaning process, or, if a probe
cooking is taking place, it will light up when 5ºC is
missing for the final temperature.
It also indicates whether the oven is performing a
temperature setting process, both preheating and
cooling.
Finally, it is also used to indicate that the oven is in
setup mode.
This colour indicates that a cooking or cleaning process
is complete.
Table 2: Colour description rotary knob.
2.1.3 Cooking programs
There are 99 programs that can be edited and retrieved at will. All of them can have up
to 5 cooking phases.
There is also a manual mode that allows you to modify the cooking parameters
(camera temperature, humidity, time, etc.) without saving them in any program. This
manual mode is displayed as "PROG -" in program selection.
In user programs, it is possible to change any cooking parameters (temperature,
humidity, time, cooking mode, etc.). To do this, press the button corresponding to the
parameter to be modified and adjust the parameter value by turning the rotary knob.

13
For example, pressing the humidity button defined in Table 1 will flash the moisture
display and you can adjust the humidity level.
To leave a program in continuous mode, press the time button and turn the rotary knob
counter clockwise until "Cont" appears on the time display.
When you change any parameters of the user programs, the manual program
is automatically selected to avoid modifying the data of the original program.
There are several safety measures that prevent abnormal operation of the equipment,
of which the user must be aware during use.
In case of any error, the unit will stop and display its code (see chapter 1.6).
The oven will not operate if the door is open.
2.1.4 Cooking mode
There are three cooking modes: convection, mixed and steam. To select a particular
mode, click on the corresponding button.
Figure 5: Cooking mode selectors.
The convection mode acts as a forced convection oven without adding or removing
moisture from the firing chamber.
The combi convection mode enables intelligent, oven-controlled regulation of moisture
removal or moisture input in the cooking chamber. To do this, press the humidity
button and turn the knob to the desired value. This value is shown through the graphic
that appears in the following image, allowing 11 values; 5 for humidity contribution to
the firing chamber (the blue inferior bars labelled SMARTCLIMA, intelligent control of
water injection), 5 for humidity extraction (the upper bars labelled SMARTCLIMA red
with DRYOUT, intelligent control of humidity extraction) and a neutral value (all graphic
off).
Figure 6: Humidity setting in mixed mode.
The steam mode saturates the cooking chamber with moisture.
