2 PRODUCT DESCRIPTION

The ECO 305 eBus Gateway is a powerful interface of the latest generation that acts as a link between your

heating system and the ebusd* software. It allows you to access your heating system, independent of the

manufacturer, read and write and perform optimizations.

The eBus Gateway has been optimized especially for the communication with the software "ebusd "* and

supports the extended command set (Enhanced Mode) of ebusd*.

In addition to the eBus functions, the eBus gateway has an access point and a web server to enable easy

operation and configuration. You can communicate via the LAN interface using the ASCII text protocol with

up to 2 data connections.

The ECO 305 is a new eBus coupler with a standard eBus data interface and "Enhanced Mode" extension

for the ebusd software. The gateway does not perform any data analysis or evaluation itself.

The fully automatic level adjustment takes place in a few seconds on your eBus, so that a cumbersome

manual adjustment is no longer necessary.

You can conveniently change device settings, perform software updates and view device data via the web

server. The web server can be accessed via the LAN and via the access point (activated at the push of a

button).

The ECO 305 eBus Gateway is a low maintenance industrial device because it does not use Linux. It has

been programmed natively and no unknown libraries are used.

Extensive software support is available via ebusd** on the web. Additionally, we provide the free eConfig tool

for debug purposes.

Please note that the ECO 305 is not supported by the Vaillant vrDIALOG software.

4 ECO 305 eBus Gateway

The ECO 305 eBus Gateway offers several advantages that result in potential savings of

up to 25%* in heating costs and an increase in living comfort.

Here are some ways the gateway can help:

•Optimization of heating control

By accessing your heating system and being able to read and write to it, you can control and adjust

heating parameters more precisely. This allows you to operate your heating more efficiently and

reduce unnecessary energy consumption.

•Improved control of the room temperature

The ECO 305 gateway in combination with the ebusd software allows you to control and adjust the

room temperature more precisely. You can set up individual schedules and temperature profiles to

improve home comfort and save energy at the same time.

•Remote access and control

Thanks to the gateway's web server and access point function, you can conveniently access and

control your heating system from anywhere. This gives you flexible and easy remote monitoring and

control to optimize home comfort while minimizing energy consumption.

It is important to note that actual heating cost reduction and improvement in home comfort depend on

various factors, such as the efficiency of your heating system, building insulation and your individual usage

patterns. However, the ECO 305 eBus Gateway, together with the ebusd** software, offers you the

possibility to better control and optimize these aspects for potential savings and improved comfort.

*The stated heating cost reduction of up to 25% is for illustrative purposes only and may vary depending on

individual circumstances. It is not a guaranteed savings.

**ebusd is not software by ESERA GmbH. We do not assume any liability, promise of function or support for

this software.

DATA INTERFACE

The ECO gateway is equipped with an Ethernet interface that allows a speed of 10/100Mbit. It supports

different data protocols like TCP/IP or UDP. Up to 2 data connections can be used in parallel, which

enables efficient communication and data transfer. The Ethernet interface provides a reliable and fast

connection for data exchange between the gateway and other devices or systems.

ASCII TEXT PROTOCOL

The ECO 305 gateway ensures a direct and unaltered transmission of the data transmitted via the

eBus. It outputs the data in its native form via the data interface without evaluating or analyzing it. The

gateway forwards the data without any additional processing or interpretation. This ensures that the

received data is transmitted to the user unchanged and true to the original.

SELF-SUFFICIENT MANAGEMENT

The eBus gateway ECO 305 enables the independent reading of communication data of the eBus and

also offers the possibility to transfer commands to the eBus. This allows various actions to be carried

out, such as triggering a heating system or transmitting parameters to the central heating system. With

the help of the gateway, data can be written to and read from the eBus heating bus to control the

heating center or peripheral components such as pumps, mixers or a living room control unit. However,

it is important to note that the correctness of the command data is always the responsibility of the user.

The gateway itself does not perform any write or read actions independently.

DESIGNED FOR ALL eBus HEATING SYSTEMS

The eBus is a cross-company bus system used in heating construction. The ECO 305 eBus gateway

enables the connection with all heating systems which have this heating data bus. Please check

whether your heating system is also supported by the ebusd evaluation system. For more information,

please visit the ebusd website at www.ebusd.de.

VOLTAGE SUPPLY

For the power supply, the ECO 305 is equipped with an integrated power supply unit that supports a wide-

range voltage input of 100VAC - 240VAC. This makes it ideally suited for stationary operation in a control

cabinet or control box. This voltage input option allows flexible installation of the gateway in different

environments and ensures a reliable power supply for the operation of the device.
