Intelligent solutions for managing the heating system and connecting to the remote monitoring system

Danfoss solutions are comprehensive in every way and tailored to the specific application. We cover almost all application possibilities in this area. Solutions with Danfoss “Intelligent” controllers provide superior control and management of heating systems. We not only supply controllers, but also unique software that enables remote monitoring and control of district heating systems. There are many good reasons to choose a solution that allows you to remotely monitor, control and, if necessary, service your system, regardless of whether the system regulates heating in urban buildings or rural communities. Danfoss offers the optimal solution for each of your applications.

Systems for remote monitoring, management of heating systems and data acquisition are nowadays a necessity and a technical standard – a standard that contributes both to energy efficiency and energy saving, as well as to the optimal exploitation of your installation. Our solutions cover all traditional forms of district heating and its alternatives, such as biomass plants. The Danfoss platform will provide better and simplified control over the system, which not only optimizes management processes, but also brings savings and protects the environment. In district heating networks, you often have high-capacity consumers that consume energy in an irrational way, which leads to significant energy consumption and waste. Here, it is important to optimally manage the district heating system, both at the heat sources and at the end user. The Danfoss electronic controller ECL 310 and ECL 210 will not only simplify the management of the plant, but also save energy and help achieve the required comfort.

Act proactively in service delivery, thanks to an effective monitoring and alarm system that can isolate and eliminate problems – even before the user knows they exist. For example, if the starting temperature is too high, the system will automatically activate an alarm to warn of excessive energy consumption.

ECL Comfort allows you to easily optimize performance and system operation, leading to energy savings and longer system life. A properly installed and commissioned electronic controller is a prerequisite for a stable and functional heating system. Simple installation and an intuitive interface allow the ECL Comfort controller to be installed correctly for maximum benefit for both the user and the heat energy supplier.

For the end user, ECL Comfort controllers primarily help to achieve comfort with the minimum possible energy consumption. Lower energy consumption can be registered by the Sonometar™ calorimeter connected to the ECL Comfort regulator. Savings on the heating bill will return the investment within a reasonable time. The level of comfort is of course still the same, and the setup is made easier by the user-friendly interface, which is modernly designed and adapted to the application.
