It`s not the size which determines the power, but rather each individual component.
What makes the difference between a good and an excellent technical solution? Reliability, the power of innovation, with such a head start - anyone can name the result. But how can this be achieved? Is there a formula which can be transferred to all industries? We think there is.
The quality of a total solution is determined by the quality of its components. A fault in a component which only costs a few cents can paralyse everything. Perfection down to the smallest detail is therefore a basis of our philosophy as a supplier of mechatronic components. Another is attuning the individual elements optimally to one another. Therefore, we see ourselves as our customers` active partner when it comes to developing new products.
Our record proves we are right. For many years, mechatronic elements by Cherry have been synonymous with the highest quality and reliability. This principle has also made us one of the leading suppliers of electronic components. Regardless of whether you use our products in household appliances, industrial applications, in the automobile industry or for input systems - you can rely on safety and comfort in addition to reliable functionality.
Philosophy

Customer satisfaction grows with quality. And quality with proximity to the customer.
With ever-shorter product cycles, the development time for new products is also being reduced. In order to guarantee maximum quality nevertheless, close cooperation among all partners is important. We interpret the term ,,close cooperation" in an old-fashioned way - and insofar as possible, we prefer personal contact with our partners.
To be as close to our customers as possible was the principle of Cherry Electrical Products Corporation, which was founded in the USA in 1953. In 1964 we established a subsidiary in Germany and in 1972 in England. In the meantime, our locations in Europe include France and the Czech Republic, and they employ approximately 2,000 people. Proximity on location allows us to react quickly to regional or individual requirements. And this is a part of our recipe for quality, which enabled Cherry to generate revenue of EUR 200 million in Europe in 2005. Further locations will also depend on you. With our flexible production network, we are in a position to react to customer and market requirements.

Success doesn`t come from the clear blue sky. It`s the result of ideas and foresight.
Growth and success across more than 50 years are no accident, but the result of a sustainable company strategy. A strategy which is applied equally to customers, employees, our own products and the environment. And this guarantees that our innovations will fall on fertile ground in the long and short term and it will ensure growth for us and our partners.
Quality and environment: For us, environmental consciousness is more than the fulfilment of a duty; we live it every day. Therefore, years ago we introduced an integrated management system based on the ISO 9001, ISO 14001 and TS 16949 standards, whose quality and environmental standards have become second nature for our employees. In order to comply we must fulfil and even exceed the requirements of our customers, suppliers, investors, employees and, last but not least, the public, through consistent process orientation. Cherry Auerbach was awarded the title ,,Factory of the Year 2005" as a testimony to this acheivement. Global values Cherry Corporation associates are focused on achieving the Global Vision through: · Documentation, communication, and implementation of the Global Vision to all stakeholders including customers, suppliers, employees, investors, and any interested parties · Establishment and review of measurable goals and objectives that support our Global Vision and Values · Continual improvement in everything we do as a means of reducing cost, improving quality, and delivering superior customer service, all with the goal of providing enhanced value to our customers · Uncompromising compliance with all applicable worldwide and local health, safety and environmental requirements and regulations with a focus on pollution prevention · Encouragement of open and active participation by stakeholders worldwide to ensure success Global vision: The Cherry Corporation is committed to the design of innovative products which meet or exceed our customers needs, the delivery of world class product and service quality, total customer satisfaction, and a safe and healthy environment for our employees and our global community.

Expertise in high-tech. And in the household.
A multitude of appliances make housework easier today. Cherry is a leading international supplier with many years` experience in developing and manufacturing electronic components and switch solutions for the household appliance industry. Whether for cooking, baking, dishwashing, washing clothes or in the sanitary sector discrete Cherry components, switches and controls help in many applications.
Leading manufacturers in the household appliance and consumer goods industry are among our customers. One of our special strengths is innovative input units: backlit, splash-proof operating panels with precisely-defined tactile response and free arrangement of the keys. The largest standard selection of pathless operated touch control controls in patented infrared technology with integrated, modern combinatorial circuit parts. Rotary selectors on an inductive contactless basis, which detect the switch setting and enable a completely free layout on the switching point number and angle. From this and with our expertise in the areas of cooking, baking, washing and drying clothes and dishwashing, we develop and manufacture application-specific regulation electronics and program controls.
For example, you will find our products in modern vitroceramic cooktops with contactless operation and integrated display, which make cooking safer and more comfortable. The infrared touch control controls all necessary processes and prevents faulty operation with intelligent sensor evaluation. The integratable automatic pot detection disables heating without a pot, thus making your household safer and saving electric energy. Additional areas of application for our products are tumble-dryers. With the input unit, various drying programmes can be selected. Displays inform the user about the current programme status and the remaining time. The modern microprocessor control evaluates sensors and input information and ensures an efficient, smooth, timeoptimised programme flow.
Cost-effective and reliable radio wave technology as in the keyboard sector is making increased inroads into our products; for example, there is a remote control for inputting and displaying the water temperature of a sink heater. Our expertise profile is rounded out with electronic 3-phase induction motor controls according to the space vector modulation process as they are used in modern washing machines.

Comfort and safety, which can no longer be dismissed from your thoughts. In all areas of life.
Our electronic components enable not just more functionality, time, energy and resource efficiency in the household; they also contribute to greater comfort and security. In industry, data technology and in automobiles, our expertise is the basis for many innovative solutions.
Dynamic bus systems with distributed intelligence simplify the construction of flexible controls. Position control systems with memory function enable multi-axis control of comfort seats in automobiles, in the furniture industry and for adjustable sickbeds. To replace circuit boards, proven, plastic-coated metallic lead frames are used for the three-dimensional construction of components. They integrate the function of the bearing housing parts with the electric connection of the components and the plug connections. Alternatively, we solder electro components such as sensors directly onto flexible printed circuits (FPC). Intelligent access control systems prevent the unauthorised use of computer systems and access to rooms.
Building blocks for the digital signature and thus the highest data security are magnetic and smart card readers and fingerprint recognition, which combine easy access with maximum security. More comfort is also a feature of our newest keyboards, which in addition to ergonomically-optimised operation and new additional functions also offer other components, e. g. integrated solar cells or touch pads with which they can be equipped, and which stay in contact with the PC via radio (currently up to 2,4 GHz).

Our products have already survived a lot. Especially in our test laboratory.
In a multitude of tests, our new developments must prove their reliability and long service life. In special test stations, we conduct qualifications of components and materials with respect to their suitability for our products as well as development-related measurements and tests of complete products.
Environmental simulation
Functional tests and lifespan tests for heat, cooling and humidity as well as vibration and shock tests.
Reliability and lifespan tests Reliability and lifespan tests
Electrical and mechanical durability tests under normal and increased operational requirements also with ageing simulation, e. g. due to temperature loads, monitor adherence of the calculated values for reliability and lifespan (MCBF -> MTBF). Here all partial functions are regarded: whether IR diodes or switch transistors. Authorisations and certifications for safety and EMC: Test for approval by the global testing stations and for customer-specific certifications (VDE, KEMA, UL, CSA, etc.) Creation of the prerequisites for applying the CE seal of approval.
Tests of the electromagnetic compatibility (EMC)
Whether line-related or externally-produced fields and impulses, our components must work surely and reliably even under the influence of electromagnetic interference. Therefore, we conduct ESD, burst and surge tests as well as power failure tests in-house. On the other hand, our components may not interfere with other devices. Therefore, we make exact emission measurements.

As flexible and efficient as our products: our production
Our mechatronics manufacturing: the components are produced on modern assembly lines. Latest generation SMD insertion robots place finepitch components on circuit boards with absolute precision. The panels are automatically separated on equipment integrated into the line.
We master new technologies such as chip-on-board without a problem. Conventional, wired components are wavesoldered in nitrogen for a controlled, highquality result. Linked assembly lines with integrated material handling systems, laser labeling equipment, testing and measurement stations deliver outstanding, consistent results. 100 % performance testing extended to include in-circuit testing, helps to guarantee the quality of the delivered product. The high degree of automation is the basis for economical production and thus for a competitive price level.
The most important success factors are, now as before, our employees, who work in self-guided, autonomous manufacturing groups Ongoing training ensures that we always work according to the most modern methods and knowledge. Flexible work schedules enable on-demand production and increase our ability to react with respect to delivery times and last-minute modifications. Our employees are themselves entirely responsible for the quality of their work, they optimise the process flows individually and they always strive to improve.

IR touch control controls for household appliances
Cooktop controls
IR sensor technology
Cherry`s patented sensor system for the touch controls sends infrared light through the vitroceramic surface. During operation, the infrared light is reflected, a microcontroller evaluates the reflection. Software detects whether the operation is intentional. Faulty operation, e. g. caused by cleaning, children, pots which have boiled over, pets or foreign light is excluded by intelligent software. Based on the optical principle, the controls are not sensitive to humidity, electromagnetic or other influences. Cherry IR touch controls calibrate themselves automatically after they are connected to the mains supply. During operation, the sensors adjust independently to changed light conditions, and thus remain operable at all times.
Slider technology
To make the operation of cooktops still easier and more comfortable, Cherry has developed a completely new generation of operating sensors for cooktops based on infrared technology. With the slider technology, a new type of IR sensor line enables both, the selection of the heater and the choice of the heat setting with the single touch of a finger. By sliding a finger on the operating line, the heat setting can be varied constantly without having to enter repeated commands to turn the heat up or down. The patented technology is thus not just easy but self-explanatory for the user. It was just as important to the developers to ensure the robustness with respect to foreign light and temperature and the excellent sensitivity of the sensors for which Cherry is known.
Application
Our standard comfort modules were developed for the contactless operation of vitroceramic cooktops based on infrared technology. The differences among the various modules consists in the number of heaters, the functions available and the operating philosophy. Thus there is an optimal module for each use case.
Portfolio overview
Basic Standard Comfort
IR touch controls
With many years of experience, Cherry develops and manufactures IR touch controls as electronic switch solutions for the household appliance industry. We count all famous manufacturers among our customers. Areas of application for our touch controls in the hot sector are all types of vitroceramic cooktops and ovens for which the greatest degree of comfort and safety is offered. Applications are offered standard and customer-specifically. All of our company`s services are secured by a DIN ISO 9001-certified quality management system.
Mechanical and electronic construction
Cherry cooktop controls distinguish themselves especially through their modular, freely-configurable construction. The hardware and firmware equipment of each module can be adjusted to suit customer requirements. This individual programming permits, e.g. instead of the control of a heater, the realisation of a two-zone switch or a timer. Another innovation is the new fastening concept. With snap-in technology, the Cherry controls can be fastened into the cooktop easily and without screws.

Pot detection
Zone control
The pot/pot size detection is based on the inductive principle. The sensors of the control detect precisely and with stable temperature the smallest changes in inductivity, caused just by the setting-down or removal of pots and pans. When setting down on a two or three-zone heating element, the control also detects the pot diameter and adjusts the heat diameter to the pot or pan automatically. This patented process is not just comfortable; it also helps to reduce energy consumption and ensures greater safety when cooking. Up to 16 cooktop configurations can be stored in the control`s memory, which makes the module universally applicable.
· Opto-coupled serial interface for communication with cooktop · Connection of up to 6 heaters equipped with inductive pot detection sensors · Sensor connection with cost-effective ,,twisted-pair" cabling and RAST 2.5 contacts · Open communication protocol · Programmable detection switch thresholds for all common heating elements with inductive pot detection sensors · ,,Ready to Use" with the Cherry standard comfort modules SCM I, SCM II, SCM III, SCM VI as well as the Multi Module MM II
Dual/Triple Zone Switch
The zone switch was developed for multizone heating elements. The module is used in connection with rotary selection switches. The zone switch is activated with an additional contact on the rotary selection switch. After there is mains power, the module conducts a basic calibration. During operation, the IR sensor adjusts itself automatically to changing light conditions. By activating the sensor, an additional zone is switched on or off. With a three-zone cooking zone, first the middle and then the outer zone is activated by activating the sensor repeatedly. If it is activated again, then first the outer and then the middle zone is deactivated again. Faulty operation is detected by the implemented software and prevented. Possible variants for a cooktop · Dual zone switch · Triple zone switch Combinations and other versions on request.
Warming zone switch
This module enables the complete control of a warming zone in a combination or touch cooktop. If the warming zone control unit is activated, it is switched on by touching the zone sensor. Light-up displays provide the user with clear information about the selected operating state. Another comfort feature of this control is the detection and prevention of faulty operation with the corresponding software.

The module also has an individual residual heat display: this function calculates the residual heat and displays it independently, that is, even after the cooktop is switched off. An operation time limit switches the warming zone off automatically after 8 hours of continuous operation for safety reasons. The warming zone control is fully isolated from the mains, has a low standby consumption (< 1 W) and corresponds to the latest specifications. The module is delivered with the new snap-in fastening technology, which enables screwless mounting in your cooktop.

It`s not the size which determines the power, but rather each individual component.
What makes the difference between a good and an excellent technical solution? Reliability, the power of innovation, with such a head start - anyone can name the result. But how can this be achieved? Is there a formula which can be transferred to all industries? We think there is.
The quality of a total solution is determined by the quality of its components. A fault in a component which only costs a few cents can paralyse everything. Perfection down to the smallest detail is therefore a basis of our philosophy as a supplier of mechatronic components. Another is attuning the individual elements optimally to one another. Therefore, we see ourselves as our customers` active partner when it comes to developing new products.
Our record proves we are right. For many years, mechatronic elements by Cherry have been synonymous with the highest quality and reliability. This principle has also made us one of the leading suppliers of electronic components. Regardless of whether you use our products in household appliances, industrial applications, in the automobile industry or for input systems - you can rely on safety and comfort in addition to reliable functionality.
Philosophy

Customer satisfaction grows with quality. And quality with proximity to the customer.
With ever-shorter product cycles, the development time for new products is also being reduced. In order to guarantee maximum quality nevertheless, close cooperation among all partners is important. We interpret the term ,,close cooperation" in an old-fashioned way - and insofar as possible, we prefer personal contact with our partners.
To be as close to our customers as possible was the principle of Cherry Electrical Products Corporation, which was founded in the USA in 1953. In 1964 we established a subsidiary in Germany and in 1972 in England. In the meantime, our locations in Europe include France and the Czech Republic, and they employ approximately 2,000 people. Proximity on location allows us to react quickly to regional or individual requirements. And this is a part of our recipe for quality, which enabled Cherry to generate revenue of EUR 200 million in Europe in 2005. Further locations will also depend on you. With our flexible production network, we are in a position to react to customer and market requirements.

Success doesn`t come from the clear blue sky. It`s the result of ideas and foresight.
Growth and success across more than 50 years are no accident, but the result of a sustainable company strategy. A strategy which is applied equally to customers, employees, our own products and the environment. And this guarantees that our innovations will fall on fertile ground in the long and short term and it will ensure growth for us and our partners.
Quality and environment: For us, environmental consciousness is more than the fulfilment of a duty; we live it every day. Therefore, years ago we introduced an integrated management system based on the ISO 9001, ISO 14001 and TS 16949 standards, whose quality and environmental standards have become second nature for our employees. In order to comply we must fulfil and even exceed the requirements of our customers, suppliers, investors, employees and, last but not least, the public, through consistent process orientation. Cherry Auerbach was awarded the title ,,Factory of the Year 2005" as a testimony to this acheivement. Global values Cherry Corporation associates are focused on achieving the Global Vision through: · Documentation, communication, and implementation of the Global Vision to all stakeholders including customers, suppliers, employees, investors, and any interested parties · Establishment and review of measurable goals and objectives that support our Global Vision and Values · Continual improvement in everything we do as a means of reducing cost, improving quality, and delivering superior customer service, all with the goal of providing enhanced value to our customers · Uncompromising compliance with all applicable worldwide and local health, safety and environmental requirements and regulations with a focus on pollution prevention · Encouragement of open and active participation by stakeholders worldwide to ensure success Global vision: The Cherry Corporation is committed to the design of innovative products which meet or exceed our customers needs, the delivery of world class product and service quality, total customer satisfaction, and a safe and healthy environment for our employees and our global community.

Expertise in high-tech. And in the household.
A multitude of appliances make housework easier today. Cherry is a leading international supplier with many years` experience in developing and manufacturing electronic components and switch solutions for the household appliance industry. Whether for cooking, baking, dishwashing, washing clothes or in the sanitary sector discrete Cherry components, switches and controls help in many applications.
Leading manufacturers in the household appliance and consumer goods industry are among our customers. One of our special strengths is innovative input units: backlit, splash-proof operating panels with precisely-defined tactile response and free arrangement of the keys. The largest standard selection of pathless operated touch control controls in patented infrared technology with integrated, modern combinatorial circuit parts. Rotary selectors on an inductive contactless basis, which detect the switch setting and enable a completely free layout on the switching point number and angle. From this and with our expertise in the areas of cooking, baking, washing and drying clothes and dishwashing, we develop and manufacture application-specific regulation electronics and program controls.
For example, you will find our products in modern vitroceramic cooktops with contactless operation and integrated display, which make cooking safer and more comfortable. The infrared touch control controls all necessary processes and prevents faulty operation with intelligent sensor evaluation. The integratable automatic pot detection disables heating without a pot, thus making your household safer and saving electric energy. Additional areas of application for our products are tumble-dryers. With the input unit, various drying programmes can be selected. Displays inform the user about the current programme status and the remaining time. The modern microprocessor control evaluates sensors and input information and ensures an efficient, smooth, timeoptimised programme flow.
Cost-effective and reliable radio wave technology as in the keyboard sector is making increased inroads into our products; for example, there is a remote control for inputting and displaying the water temperature of a sink heater. Our expertise profile is rounded out with electronic 3-phase induction motor controls according to the space vector modulation process as they are used in modern washing machines.

Comfort and safety, which can no longer be dismissed from your thoughts. In all areas of life.
Our electronic components enable not just more functionality, time, energy and resource efficiency in the household; they also contribute to greater comfort and security. In industry, data technology and in automobiles, our expertise is the basis for many innovative solutions.
Dynamic bus systems with distributed intelligence simplify the construction of flexible controls. Position control systems with memory function enable multi-axis control of comfort seats in automobiles, in the furniture industry and for adjustable sickbeds. To replace circuit boards, proven, plastic-coated metallic lead frames are used for the three-dimensional construction of components. They integrate the function of the bearing housing parts with the electric connection of the components and the plug connections. Alternatively, we solder electro components such as sensors directly onto flexible printed circuits (FPC). Intelligent access control systems prevent the unauthorised use of computer systems and access to rooms.
Building blocks for the digital signature and thus the highest data security are magnetic and smart card readers and fingerprint recognition, which combine easy access with maximum security. More comfort is also a feature of our newest keyboards, which in addition to ergonomically-optimised operation and new additional functions also offer other components, e. g. integrated solar cells or touch pads with which they can be equipped, and which stay in contact with the PC via radio (currently up to 2,4 GHz).

Our products have already survived a lot. Especially in our test laboratory.
In a multitude of tests, our new developments must prove their reliability and long service life. In special test stations, we conduct qualifications of components and materials with respect to their suitability for our products as well as development-related measurements and tests of complete products.
Environmental simulation
Functional tests and lifespan tests for heat, cooling and humidity as well as vibration and shock tests.
Reliability and lifespan tests Reliability and lifespan tests
Electrical and mechanical durability tests under normal and increased operational requirements also with ageing simulation, e. g. due to temperature loads, monitor adherence of the calculated values for reliability and lifespan (MCBF -> MTBF). Here all partial functions are regarded: whether IR diodes or switch transistors. Authorisations and certifications for safety and EMC: Test for approval by the global testing stations and for customer-specific certifications (VDE, KEMA, UL, CSA, etc.) Creation of the prerequisites for applying the CE seal of approval.
Tests of the electromagnetic compatibility (EMC)
Whether line-related or externally-produced fields and impulses, our components must work surely and reliably even under the influence of electromagnetic interference. Therefore, we conduct ESD, burst and surge tests as well as power failure tests in-house. On the other hand, our components may not interfere with other devices. Therefore, we make exact emission measurements.

As flexible and efficient as our products: our production
Our mechatronics manufacturing: the components are produced on modern assembly lines. Latest generation SMD insertion robots place finepitch components on circuit boards with absolute precision. The panels are automatically separated on equipment integrated into the line.
We master new technologies such as chip-on-board without a problem. Conventional, wired components are wavesoldered in nitrogen for a controlled, highquality result. Linked assembly lines with integrated material handling systems, laser labeling equipment, testing and measurement stations deliver outstanding, consistent results. 100 % performance testing extended to include in-circuit testing, helps to guarantee the quality of the delivered product. The high degree of automation is the basis for economical production and thus for a competitive price level.
The most important success factors are, now as before, our employees, who work in self-guided, autonomous manufacturing groups Ongoing training ensures that we always work according to the most modern methods and knowledge. Flexible work schedules enable on-demand production and increase our ability to react with respect to delivery times and last-minute modifications. Our employees are themselves entirely responsible for the quality of their work, they optimise the process flows individually and they always strive to improve.

IR touch control controls for household appliances
Cooktop controls
IR sensor technology
Cherry`s patented sensor system for the touch controls sends infrared light through the vitroceramic surface. During operation, the infrared light is reflected, a microcontroller evaluates the reflection. Software detects whether the operation is intentional. Faulty operation, e. g. caused by cleaning, children, pots which have boiled over, pets or foreign light is excluded by intelligent software. Based on the optical principle, the controls are not sensitive to humidity, electromagnetic or other influences. Cherry IR touch controls calibrate themselves automatically after they are connected to the mains supply. During operation, the sensors adjust independently to changed light conditions, and thus remain operable at all times.
Slider technology
To make the operation of cooktops still easier and more comfortable, Cherry has developed a completely new generation of operating sensors for cooktops based on infrared technology. With the slider technology, a new type of IR sensor line enables both, the selection of the heater and the choice of the heat setting with the single touch of a finger. By sliding a finger on the operating line, the heat setting can be varied constantly without having to enter repeated commands to turn the heat up or down. The patented technology is thus not just easy but self-explanatory for the user. It was just as important to the developers to ensure the robustness with respect to foreign light and temperature and the excellent sensitivity of the sensors for which Cherry is known.
Application
Our standard comfort modules were developed for the contactless operation of vitroceramic cooktops based on infrared technology. The differences among the various modules consists in the number of heaters, the functions available and the operating philosophy. Thus there is an optimal module for each use case.
Portfolio overview
Basic Standard Comfort
IR touch controls
With many years of experience, Cherry develops and manufactures IR touch controls as electronic switch solutions for the household appliance industry. We count all famous manufacturers among our customers. Areas of application for our touch controls in the hot sector are all types of vitroceramic cooktops and ovens for which the greatest degree of comfort and safety is offered. Applications are offered standard and customer-specifically. All of our company`s services are secured by a DIN ISO 9001-certified quality management system.
Mechanical and electronic construction
Cherry cooktop controls distinguish themselves especially through their modular, freely-configurable construction. The hardware and firmware equipment of each module can be adjusted to suit customer requirements. This individual programming permits, e.g. instead of the control of a heater, the realisation of a two-zone switch or a timer. Another innovation is the new fastening concept. With snap-in technology, the Cherry controls can be fastened into the cooktop easily and without screws.

Pot detection
Zone control
The pot/pot size detection is based on the inductive principle. The sensors of the control detect precisely and with stable temperature the smallest changes in inductivity, caused just by the setting-down or removal of pots and pans. When setting down on a two or three-zone heating element, the control also detects the pot diameter and adjusts the heat diameter to the pot or pan automatically. This patented process is not just comfortable; it also helps to reduce energy consumption and ensures greater safety when cooking. Up to 16 cooktop configurations can be stored in the control`s memory, which makes the module universally applicable.
· Opto-coupled serial interface for communication with cooktop · Connection of up to 6 heaters equipped with inductive pot detection sensors · Sensor connection with cost-effective ,,twisted-pair" cabling and RAST 2.5 contacts · Open communication protocol · Programmable detection switch thresholds for all common heating elements with inductive pot detection sensors · ,,Ready to Use" with the Cherry standard comfort modules SCM I, SCM II, SCM III, SCM VI as well as the Multi Module MM II
Dual/Triple Zone Switch
The zone switch was developed for multizone heating elements. The module is used in connection with rotary selection switches. The zone switch is activated with an additional contact on the rotary selection switch. After there is mains power, the module conducts a basic calibration. During operation, the IR sensor adjusts itself automatically to changing light conditions. By activating the sensor, an additional zone is switched on or off. With a three-zone cooking zone, first the middle and then the outer zone is activated by activating the sensor repeatedly. If it is activated again, then first the outer and then the middle zone is deactivated again. Faulty operation is detected by the implemented software and prevented. Possible variants for a cooktop · Dual zone switch · Triple zone switch Combinations and other versions on request.
Warming zone switch
This module enables the complete control of a warming zone in a combination or touch cooktop. If the warming zone control unit is activated, it is switched on by touching the zone sensor. Light-up displays provide the user with clear information about the selected operating state. Another comfort feature of this control is the detection and prevention of faulty operation with the corresponding software.

The module also has an individual residual heat display: this function calculates the residual heat and displays it independently, that is, even after the cooktop is switched off. An operation time limit switches the warming zone off automatically after 8 hours of continuous operation for safety reasons. The warming zone control is fully isolated from the mains, has a low standby consumption (< 1 W) and corresponds to the latest specifications. The module is delivered with the new snap-in fastening technology, which enables screwless mounting in your cooktop.
