2.4 MEC System – overview
Transparent, efficient, smart
The MEC System (Master Energy Control) is a platform
for planning individual and customer-specific energy
supply systems. With the MEC system, you can combine
and control different plant types and field devices to
achieve an efficient energy system via user interface. The
MEC system is used in commercial, industrial and
communal sectors and is sold as system solution with
Bosch heat sources.
Activation
The MEC system controls different plant types
(e. g. boilers, CHPs) and the required system field
devices (e. g. pumps, valves). For this purpose, it
provides a large range of interfaces and, besides
integration of Bosch devices, it allows for integration
of existing and third-party products.
System control
The system control is the core know-how of the MEC
systems. As manufacturer of energy generation plants,
Bosch used its entire expert knowledge for developing
control and allows in consequence for optimum system
control with adherence to the system's operating
conditions.
Control for energy generation
The MEC system integrates for energy generation as
standard the following plant types:
• Warm water boiler
• Hot water boiler
• Steam boiler
• Biomass boiler
• CHP modules
• Solar
• Heat pumps
• Buffer storage tanks
• External heat
Further systems and plants are available on request.
Control for heat distribution
The range of functions for control of heat distribution
comprises:
• Local heat network
• Heating circuits
• Fans
• Heating circuits
• DHW heating
Further functions and control of systems and devices are
available on request.

System access
The MEC system gives humans and machines access to
the entire system:
• Via an integrated local web server, the user can
access the system using any terminal device
(such as PC, notebook or tablet) in the network with
a standard web browser.
• With the modern and intuitive user interface, the user
can access the complete system and each individual
plant.
• Having a large number of interfaces, the MEC system
allows for integration in super-ordinate systems, such
as building control systems, process control systems,
energy management and virtual power plant systems.
• Using MEC remote, the user has the opportunity to
access the local system from the Internet via a safe
connection.
Web and IP technologies
Web and IP technology have the following benefits:
• HMI scalable to different screen sizes
• Mouse and touch screen operation
• Unlimited number of terminal devices for visualisation
• Location-independent for terminal devices and
controller
• Simple network building with standard components
for large factory sites
• Easy integration in corporate networks
Comprehensive HMI functionality
The modern and intuitive HMI of the MEC system has
many benefits:
• Coloured, clear visualisation of states, temperatures
and performance
• Visualisation of device, system and operation
• User management
• Alarm management with alarm history
• Appliance configuration via HMI system
• Search
• Dashboard function
• Energy monitoring
• Diagram displays
• Export and print-out of graphs
• Transmission of alarms via e-mail, text message, fax
• Run time prognosis of CHP module
New HMI standards
The MEC system uses new standards for visualisation:
• The concept of operation is tuned to the end
customer's requirements
• Intuitive and new operation
• Structured and clear design
• Modern design
