Danfoss DECS 2.0 Energy Control System User Guide
Thank you for buying a Danfoss product
Introduction
Operating the DECS 2.0 system
The Danfoss Energy Control System (DECS) is a web-based software program that enables the user to remote control and monitor the parameter settings in the controllers and also monitor actual, reference and historical values of sensors and meters connected to the controller.
This user guide is intended for private end users of district heating installations who want to monitor their heat consumption and make changes to the controller parameters. It describes the most common functions which a private end user will usually make use of. Please consult the DECS 2.0 Operating Guide for a description of all available features.
The heating installation can be monitored and controlled from everywhere as DECS provides an intuitive user interface that is accessible from a web browser on a PC, laptop or smartphone connected to the internet.
To operate the DECS 2.0 system, open the web browser and enter the public IP address of the DECS 2.0 server in the address field. 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 district heating utility 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 field of the web browser instead of the IP address.
Please use one of the following web browsers for full compatibility:
- Mozilla Firefox
- Internet Explorer
- Google Chrome
Web browser must comply with requirements of Atvise SCADA Client software.
For details about specific browser versions compatible with Atvise please visit
