Rotary control

Used to edit values and navigate through the configuration menus.

It also has a multi-coloured LED display, which indicates the status of the oven. For more information, see chapter 2.1.2.

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.

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

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.

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.

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.

This colour indicates that the oven is not cooking or cleaning. The oven's not working.

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.

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:

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.

When you change any parameters of the user programs, the manual program is automatically selected to avoid modifying the data of the original program.

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.

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.

In order to prolong the life of your oven, it may automatically reduce the maximum cooking chamber temperature.

The table below summarizes the characteristics of each of them.

Table 4: Cooking modes in MyChef ovens.

In all cooking modes it is possible to humidify the chamber at will. To do this, press the HUMIDITY button until the blue humidity graph bars on the left side of the LCD display light up. In the case of steam cooking, the SMARTCLIMA icon disappears and intelligent humidity control is deactivated by passing the steam injection control to the user.

2.1.5 Cooking control

2.1.5.1 Cooking by temperature and time control

The temperature and time control mode is the simplest, we simply choose a temperature and time by rotating the circular knob after pressing the TEMPERATURE and TIME buttons respectively.

When the START/STOP button is pressed, the oven will start heating the chamber and stop after the set time has elapsed. At this point, the timer will display the keyword "End", the oven will beep for one second and the door opening icon will light up until the user finishes cooking by slightly pressing the START/STOP button.

Example of cooking at 90º for 10 minutes:

Figure 7: Example. Cooking 90ºC in steam mode for 10

minutes.

Figure 7: Oven temperature.

2.1.5.2 Temperature cooking and time control with temperature adjustment

The temperature and time firing control mode with temperature setting is very similar to the previous method. In this mode the oven automatically brings the temperature in the chamber to the value selected by the user so that when the opening and loading of

the feed occurs, therefore the start of cooking, the temperature in the chamber is equal to the selected one. The oven automatically calculates the ambient temperature in the chamber and decides whether a heating or cooling process should be carried out depending on the desired value.

To use this mode, as in the previous case, we choose the temperature and cooking time by pressing the TEMPERATURE and TIME buttons respectively. This time, instead of pressing the "START/STOP" button to start the process, press the SETUP key.

This key has two small visual indicators to the left and right, one blue and one red. Depending on the light that comes on, a cooling (blue) or preheating (red) will be carried out.

Before cooking begins, the process indicator for the required process according to the temperature of the chamber will blink indicating that pressing the button initiates a preheating or cooling process. When pressed, the indicator will stop flashing and will remain permanently lit indicating that the process has started.

You can cancel the preheating and continue cooking by pressing the START/STOP button.

Once the oven reaches preheating temperature, it will indicate to the user that the oven can be charged by an audible and visual warning: the door opening icon will light up and the charge arrow will flash.

To avoid excessive overheating, this state is maintained for a maximum of ten minutes.

When you open the door and load the oven, the preheating program will end and the firing program will be executed.

Example of cooking at 90º for 10 minutes with preheating:

Figure 9: Example. Cooking 90ºC in steam mode for 10 minutes.

Figure 8: Oven temperature.

2.1.5.3 Temperature cooking and core probe control

The core probe controlled temperature control mode terminates cooking when the temperature in the food core is equal to the selected temperature. The chamber temperature is kept constant and equal to the value selected on the temperature display.

To use this mode, select a chamber temperature and a desired temperature at the heart of the food by pressing the TEMPERATURE and PROBE buttons respectively and adjusting them with the rotary knob. When the START/STOP button is pressed, the oven will start to warm up and stop when the core probe temperature is equal to the setpoint temperature of the probe. At this point, the timer will mark "End" until the user finishes cooking by briefly pressing the START/STOP button.

If the probe is not connected, the oven will indicate this by means of the corresponding icon flashing, and acoustically. In this case, connect the probe and press START/STOP. If the probe is connected, and the probe reading is higher than the desired temperature, the probe icon will remain fixed and cooking cannot begin. Decrease the temperature at the probe, or change the desired end temperature.

Figur3 9: Probe icon.

For this cooking mode, the multipoint probe or the sous-vide probe must be connected.

If we try to start a heart-probe-controlled program, and it is not connected, the oven will sound and visually warn and the program will not start.

When the oven is in the process of cooking controlled through a core probe, the chamber temperature display shows the temperature to be reached in the chamber, and the core probe display shows the actual temperature of the food.

Example of cooking at 90º until the temperature in the heart of the food is 55º:

Figure 12: Example. Cooking 90ºC in steam mode and core temperature 55ºC.

Figure 13: Oven temperature (blue) and core probe (yellow).

If we are performing a core probe controlled cooking cycle, the time/sound display will indicate the actual probe temperature. By pressing the PROBE button, the display for the probe will indicate the desired core probe temperature and can be modified by rotating the encoder if desired.

2.1.6 Programs edition

Programs 1 to 99 can be modified by pressing the PROG button for a few seconds after the program to be edited has been selected by rotating the knob. When an acoustic signal sounds and the "PROG" icon to the right of the LCD flashes, the firing parameters can be edited.

The first number in the phase indicator indicates the current phase and the second number indicates the total of existing phases.

To add or remove phases in programs 1 to 99 before, enter program editing mode.

If we are editing a program that has not been saved, the temperature and other values will appear empty in the display screens and the LEDs will guide us to define all cooking parameters. The indicator will blink along with the segments of the display that represent the value associated with each parameter.

If we are editing an already stored program, the values will be set and the indicators will show the parameters of the program. When selecting a parameter by pressing the corresponding button, the segments associated with it will blink and the value can be changed using the knob.

In any case we can edit the cooking mode, chamber temperature, humidity in combined mode, cooking time or probe temperature depending on the selected end condition and fan speed.

To save the program after this process is complete, press the PROG button until the acoustic signal sounds again and the program number stops flashing.

2.1.7 Step Edition

The editing of the phases can be done directly in the manual program (---) or phases can be added to the user programs. If you want to modify the phases in any user program (programs 1 to 99), you must first enter the program editing mode of that program. The editing process follows the same pattern as before using the flashing segments and indicators to edit the parameters of each phase.

Navigation between steps

To navigate between the various phases, press the STEP key slightly. The digits to the right of the STEP icon showing the current phase and the total number of existing phases will flash and can be skipped from phase to phase using the rotary knob.

2.1.7.1 Add a Step

To add a step, enter the program editing mode. If the program has only one phase, the program icon will blink and pressing the STEP button will add a new phase. If the program already contained more than one phase, press the STEP button to navigate through them until you reach the last one. At this point, pressing it again will add one more phase. After adding all desired phases, press the PROG button for a few seconds until the acoustic signal indicates that all changes have been saved.

Once a phase has been added, the firing parameters of the phase can be modified as specified in the previous subchapters.

2.1.7.2 Delete

To delete a phase, enter program editing mode. Briefly pressing the STEP button will take you from one phase to the next until you want to delete it. This will be deleted by pressing the "Convection”, “Combined" or "Steam" button (depending on the mode selected in the previous phase) whose light indicator will flash. Pressing it will erase the current step and all subsequent steps allowing you to complete the program again from the step you wanted to delete.

An example to clarify this elimination process would be to delete the second phase of a three-phase program. To start, press and hold the PROG button with the selected program until you enter edit mode. The STEP button should then be pressed to navigate from the first phase to the second. At this point, press the convection button that would blink in the upper left corner of the panel (since the second phase is supposed to be a convection phase in the example) removing all values from step 2 and step 3 altogether.

2.1.8 Starting the cooking cycle

Once the cooking parameters have been selected, either manually or in a specific program, we can start the process.

To do this, press the START/STOP key, and its indicator on the LCD will light up.

Figure 10: cooking indicator

2.1.9 End of step

At the end of a cooking cycle, the equipment visually and acoustically signals this state. Specifically:

- The visual indicator on the rotary knob lights up in green

- 3 beeps of 2 seconds are emitted, with an interval of 10 seconds.

- The keyword "End" appears on the time/sound display of the LCD display until

the user finishes cooking.

To finish cooking, press START/STOP.

2.1.10 Fast cooling

Rapid cooling is a particular use of the temperature setting mode (preheating or cooling) explained above. If a quick cooling process is desired, the preheating or cooling firing start mode must be used. To do this, select a low temperature value in manual mode, e. g. 30°C or "Off", and press the SET button.

In this mode the convection fan is switched on and the resistors are switched off. In this particular case, even if the oven door is opened, the process will not stop and the

Note that in this mode, the convection fan works when the door is open. Take appropriate precautions.

In order to be able to regulate the temperature in the chamber correctly, in certain situations (low temperature, etc.) the oven can automatically select the reduced convection speed.

Set the oven date and time when recording HACCP data.

fan will continue to rotate. This way, and with the door open, the temperature of the chamber can be lowered in a few seconds.

Once in this mode, the display for the camera probe shows the temperature of the camera probe continuously. To exit the quench mode, briefly press START/STOP.

2.1.11 Speed selection

In any cooking mode, the user can select the speed of the convection fan that best suits his needs. To do this, press the fan speed button.

If the speed indicator is off, the oven will operate at maximum convection speed. If, on the other hand, it is switched on, the oven will rotate the convection fan at a reduced speed.

Figure 15: Maximum and reduced speed.

The fan has 3 operating speeds. Low speed with pulsed operation, low without pulsed and high operation. The first one is only used for temperatures below 40ºC, the second one only for temperatures above 40ºC and the last one for temperatures above 60ºC.

2.1.12 HACCP data recording

The equipment allows the recording of temperatures and events occurring during normal use. To record data, insert a memory into the USB connector in the lower right corner of the oven.

Figure 16: USB connector housing.

This data can be retrieved using the HACCPManager software (optional). They can also be viewed from a computer.

For the use of the washing processes in as much as for the handling of the products used in the process, appropriate protections must be used.

Figure 11: HACCPManager.

2.2 Cleaning the cooking chamber

Depending on the oven model, there are two types of processes for cleaning the firing chamber: manual assisted and automatic.

The assisted manual programs are predefined in ovens that do not have a self-cleaning system. Those that do have this system have predefined the different automatic programs.

You can change the cleaning type by accessing the configuration parameters.

2.2.1 Manually assisted cleaning

This chapter applies only to ovens without self-cleaning system (optional).

Before manual cleaning, make sure you have all the necessary equipment. This material can be purchased from your local mychef dealer.

- Cleaning shower

- Spray gun for spraying cleaning products

- Distform DA21, detergent liquid and brightener in one, or equivalent:

Combination of substances, including:

o potassium hydroxide 10 - <25% o Complex mixture of glycols, sequestrants, surfactants and alkalis. o Physical appearance: Oily liquid

When the appliance is in operation, open the door slowly and carefully to avoid possible burns from the steam or hot air that may come out of the cooking chamber.

o Density 1.1 gr/cc. approx. o pH: >13

Then remove any solid food scraps/rests that may be inside the chamber manually. Do not use the manual shower faucet accessory to remove food scraps from the cooking chamber, remove them beforehand and prevent them from coming out of the drain. Do not place trays or grills during the washing process. It should always be carried out without load, to ensure proper cleaning of the equipment.

Once this is done, the assisted manual cleaning process can be started. To start the process press the CLEAN button and then press the START/STOP button to start the process.

Meanwhile, refill the spray gun with Distform DA21, degreasing liquid and polish in one. After 20 minutes of starting the semi-automatic cleaning process, the following icon will illuminate. This indicates that the door must be opened, the chamber sprayed with the spray gun and the door closed again.

Figure 12: Spraying detergent icon.

At the end of the second phase, after 20 minutes, clean the camera with a cloth to avoid damaging it. Afterwards, rinse the chamber with the shower faucet until no detergent remains. The icon below will illuminate to indicate that rinsing is required.

Figure 13: Rinse icon.

The last phase, also 20 minutes, corresponds to a drying of the chamber. If any moisture remains, wipe the inner chamber dry with a cloth.

2.2.2 Self-Cleaning System

2.2.2.1 Self-cleaning and rinsing programs

Using the MyCare cleaning system makes it possible to automatically clean the cooking chamber and has 4 wash programmes plus a rinse programme.

Automatic cleaning programs are only enabled if the oven is equipped with this option.

Use MyCare Cleanduo in ovens equipped with automatic washing system, and DA21 in ovens with manual washing system assisted. The use of other products voids the warranty.

For the use of the cleaning processes as well as for the handling of the products used in the process, appropriate protections must be used. Never touch the detergent with your hands.

Before starting any cleaning process, make sure that the water flow to the unit is open.

Cleaning programs are specifically designed to use MyCare cleanduo detergent. The special formulation of this product stands out for having twice the concentration of active product than that of most similar products available on the market. It also includes a polishing additive for a perfect all-in-one finish. This makes it possible to use only one MyCare Cleanduo tablet per wash, with the consequent savings and ease of use.

The time required to carry out each program and the use and usefulness of each program are listed in the table below.

Table 3: Self-cleaning and rinsing programmes

Before the self-cleaning cycle, remove any solid food scraps/rests that may be inside the chamber manually. Do not use the manual shower faucet accessory to remove food scraps from the cooking chamber, remove them beforehand and prevent them from coming out of the drain. Do not place trays or grills during the washing process. It should always be carried out without load, to ensure proper cleaning of the equipment.

Never place the detergent with the convection fan moving.

The automatic cleaning cycle can then be started. To do this, select one of the cleaning programs or rinse process on the control panel depending on the dirt in the chamber. To do this, press the CLEAN button and navigate through all four programs with the rotary knob. If you want to perform a short rinsing process instead of cleaning, press the RINSE button.

Before inserting the MyCare CleanDuo tablet, check that the cooking chamber temperature is not too high. If the blue temperature adjustment indicator blinks, it indicates that the temperature in the chamber must be lowered before the detergent is introduced into the chamber. In this case, press the SET button to lower the cooking chamber temperature.

Figure 20: Setting the required temperature

The oven will begin a cooling process that can be done with the door open to make it faster.

When the oven indicates this with the corresponding icon, the temperature from which it is safe to introduce the detergent into the firing chamber has been reached.

Figure 21: Cooling completed. Introduce MyCare detergent.

At this point it is important to stop the fan using the START/STOP button, open the door and insert the detergent into the dedicated housing. Once entered, close the door again to start the cleaning program.

If cooling is not required, you can place the MyCare detergent directly in its assigned space and start the cleaning or rinsing cycle by pressing the START/STOP key.

Before starting any cleaning or rinsing process, check that a temperature adjustment of the cooking chamber is not necessary.

Before starting any cleaning process other than rinsing, make sure that the detergent tablet has been placed in the oven.

To insert the detergent tablet into the chamber, it is essential to stop the fan. It is important not to introduce the detergent while it is running in order to prevent the detergent from being drawn into the air stream and endangering the health of the user.

The duration of the self-cleaning programs specified in Table 5 does not take into account any cooling of the chamber.

Never open the door of the cooking chamber during an automatic cleaning process.

Figure 22: Housing for MyCare detergent.

Once you have started the automatic process do not open the door under any circumstances, as chemicals used for cleaning and steam may escape. This situation would pose a significant risk of corrosion and burns.

The process can be stopped in case of emergency with the START/STOP button. In doing so, the process will stop and the CLEAN and RINSE icons will flash on the screen to indicate that a button must be pressed to continue.

If we press the CLEAN button the process will resume normally. Pressing the RINSE button will perform a rinse to remove all chemical residue from the chamber and finish cleaning. If you press the second key to cancel the cleaning program, it is not necessary to remove any residue from the tablet that has not dissolved using chemical

If the cleaning process has been stopped without the cleaning process being completed automatically, it is mandatory to remove all undissolved pieces of detergent tablet from the chamber before proceeding with the final rinse.

Always run a self-cleaning or rinsing program when error 26 occurs.

protective gloves. Open the door, remove all the pieces, close it and then press RINSE for perfect rinsing.

If at the end of any of the automatic cleaning processes you detect that there are any detergent residue left in the chamber (even behind the fan cover plate), perform a rinsing program or perform a thorough manual rinsing of the cooking chamber.

If there is a power failure during the cleaning process, an error message will be displayed on the control panel (error 26) when the oven is turned on again. In this case, to prevent detergent and brightener residue from remaining in the chamber, run a rinse program.

All values shall be restored except for the oven type, the number of TSC channels, the self-cleaning type, the fan type and the statistical values of the oven.

2.3.1.3 Lock

It is possible to lock the programs by accessing register 4 "Lock" of block P1 and editing the stored value, where 1 is lock and 0 is not lock. This lock prevents the user from editing the oven programs.

2.3.1.4 Light

The "Light" record number 5 of block P1 shows how long the light will remain on since any control panel command was last pressed.

This parameter must be set to change the time. If the value is greater than zero, it indicates the seconds that the light will remain on, up to a maximum of 600. If it is -1, the light will remain on permanently each time the oven is turned on.

This function will only continue with cooking in the event of a power failure and subsequent recovery of the power supply.

Table 7: Block P2, Date and time.

Each register allows you to query and edit values to enter the date and time in the oven.

2.3.3 Block P3, Configuration SAT

This block allows to consult the internal configuration parameters of the oven and facilitates the diagnosis of faults and malfunctions as well as its solution to the technical assistance service.

Table 4: Block P3, Configuration SAT.

Parameters report a very wide range of features ranging from the type of oven to fan configuration, etc. and also allow the service technician to perform tests and tests to ensure perfect operation.

2.3.3.1 NightWatch

NightWatch allows the oven to automatically continue cooking after a power failure. This feature is especially useful for unattended cooking.

This function can be disabled by your dealer. Make sure that you fully understand the risks involved.

To minimize risks, analyze the food after such a low temperature warning when it is automatically recovered from cooking, or discard it (Error 28).

Use the HACCP data record to always check firings. See chapter 2.1.12.

This function is deactivated at the factory and must be activated by your dealer.

Please note that steam extraction only works in the final moments of cooking. Therefore, this action does not occur when the oven door is opened during cooking.

This function will only be activated in time-controlled cooking.

When a cut occurs and the power supply is subsequently restored, the oven recovers the current firing (if any) and continues it with the same parameters prior to cutting.

If it is not cancelled, the MyChef oven automatically checks the temperature of the cooking chamber. If the temperature is below 56°C there may be a risk of bacterial contamination. In this case, the oven will continue cooking but will display error 28 when pressing the START/STOP button to end the firing cycle. In this case, the final user shall decide the fate of the food, taking into account the risks of possible bacterial contamination.

2.3.3.2 Automatic steam extraction from the chamber

In order to avoid burns or steam discomfort when opening the door, MyChef ovens can remove steam from the chamber at the end of the cooking process. Even when in convection mode, this extraction can be useful to eliminate steam that may be released from food in the cooking chamber.

When the oven enters the steam extraction process, a large amount of steam can escape through the chimney, depending on the saturation level. The use of a condensing hood is recommended for MyChef ovens.
