Introduction
DECS 2.0
The Danfoss Energy Control System (DECS) is a web-based SCADA software solution (Supervisory Control And Data Acquisition) for
district heating systems.
This SCADA solution is typically installed locally at the heating utility and will automatically congure its user interface and functionality
to support the application on the controller (for example Danfoss ECL Comfort 310).
The user of the DECS 2.0 system is able to remote control and monitor the parameters settings in the controllers and also monitor actual,
reference and historical values of sensors and meters connected to the controller.
Danfoss ECL Comfort 310, OPR0010 and OPR0020 controllers are supported by the auto-conguration features of DECS 2.0, but other
district heating controllers, e.g. the ECL Apex 20 controller, can also be supported by manually adding graphics and programs into DECS
2.0.
This user guide is intended for operators at district heating utilities who monitor district heating in cities and/or larger plants as well as
owners/operators of stand-alone district heating plants to ease the daily monitoring work. Data is constantly exchanged between
controllers and the DECS 2.0 server, and conguration reports and alarm reports are generated automatically. In addition the heating
station and substation installations can be controlled and monitored from everywhere, as the server provides an intuitive user interface
that is accessible from any standard browser on a PC, laptop or smartphone connected to the internet.
The present user guide contains detailed explanation of the features in the DECS 2.0 system. If you need further information on controllers
to be used together with the DECS 2.0 system, please see the below literature reference.
Additional technical literature related to the DECS 2.0 Danfoss Energy Control system:
* Data sheet on DECS 2.0 VD.HX.A1
* Quick guide for end users on DECS 2.0 VI.HX.B1
* Installation guide for technicians on DECS 2.0 VI.HX.C1

Important product information
This User Guide is associated with the DECS 2.0 software (order code no. 187B1503, 187B1504 or 187B1505).
The DECS 2.0 software can operate together with three types of District Heating controllers: OPR0010 using rmware V3.6, OPR0020
using rmware R4 to R7 and ECL Comfort 310 using P330 application key.
The DECS 2.0 visualization software can be used for three types of communication: LON, Modbus and Ethernet communication.
The DECS 2.0 system does not aect any other software or web application. DECS 2.0 does neither set requirements related to what is
installed, nor to the selection of web browser or hardware.
Basically, every web browser that supports SVG, JavaScript and asynchronous http requests should work, but based on some of the
build-in functionality, the following web browsers are supported:
* Firefox, Mozilla
* Internet explorer, Microsoft
* Chrome, Google
* Opera, Opera
For information on supported versions, please contact your system integrator or provider.
The DECS 2.0 server application is only built for 32-bit systems, running Windows XP or Windows 7.
Please see further detailed requirements in the DECS 2.0 data sheet.
If questions arise or problems occure, please contact your system integrator or provider of the DECS 2.0 system.

Accessing the DECS 2.0 user interface
To operate the DECS 2.0 software its user interface must be
accessed using one of the web browsers mentioned earlier.
Open the web browser and enter the IP address of the DECS 2.0
server in the address eld. The user interface will then be shown
in the web browser. If you need help re. the IP address, please
contact your network administrator.
Alternatively, the system integrator or IT administrator may have
assigned a domain name to the DECS 2.0 server. In this case the
domain name (URL) should be entered into the address eld of the
web browser instead of the IP address.
Language selection
All users have registered a default user language.
The language can though be changed simply by pressing the
‘Language selection’ button next to the date. This selection will
overwrite the originally set default user language.
There are 3 languages available: English, German and Italian.
All selections have to be made again if the language has been
changed during operation.
Language selection is independent of the default user language
settings, meaning that the default user language is only present if
language has not been selected by the user.

Controller overview
When pressing the ‘Controller - overview’ button, an overview of
the installation for this specic customer is shown.
The available information on the overview pictures might dier
depending on the installed district heating controller and on
which application the controller is running.
The default presented circuits for ECL Comfort 310 are depending
on the application that is installed on the district heating controller.
The default presented circuits for OPR0010 and OPR0020 are
depending on the settings generated in the DECS 2.0 software.
Using the DECS 2.0 solution, it might also be possible to make the
overview pictures for an ECL Comfort 310 t the real installation.
This is done under ‘Controller - settings’.
Before creating the picture dynamically, settings are read out from
the controller and used for default picturing.
NOTE:
Because of this the controller must be reachable before
implementing the controller in the DECS 2.0 solution.
Controller settings
To get an overview of the controller settings press the ‘Controller
- settings’ button.
The selected customer is shown in the list on the top of the display.
All attached controllers to this specic customer are shown in the
list.
The active selected controller is shown.
Controller number is added in the ‘Active controller’ section.
Default: The rst controller from the list is selected.
The controller settings are divided into 3 sections:
1. Setup
2. Time
3. Administration
The availability of this function depends on which controller is
selected.
