DSA HOME
Wall Mounted Station
General description and application
Maximum operating parameters
Danfoss district heating substations provide the link between district heating suppliers and cus­tomer installations. They contain all the necessary equipment to adjust the heat supplied for the needs of the object premises as specied in the heating supply contract. In this respect they must comply with all applicable standards and with the supplier’s technical connection conditions. Indirect connections (in which district heating and in-house systems are hydraulically isolated) incorporate components that separate the sys­tems (heat exchanger), limit the ow volume to that specied in the contract, regulate the sec­ondary supply temperature and measure energy consumption.
The DSA HOME is designed for use in high-param­eter district heating networks. It is suitable for heating single family houses. It is an alternative solution to oil or gas boilers. The DSA HOME is prepared for heating or heating and domestic hot water applications. Its wall-mounted con­struction saves space needed for installation and servicing.

Function The DSA HOME platform can be used for various
applications such as heating or heating with domestic hot water based on customer request and the needed application(s). The wall-mounted construction allows easy access to all components for maintenance and servicing purposes. Standard assembly accessories signicantly reduce the time needed to place the substation on the wall.
Heat transfer between the district heating net­work and the building installation is achieved by way of a micro plate heat exchanger, which ensures better heat transfer, higher energy e­ciency and reduced pressure loss. In addition to

the standard controller functions, the ECL310 oers easy remote access via an internet page with data logging possibilities and energy opti­misation functions such as weather compensation and auto-tuning (adaptive settings for domestic hot water parameters). For customer which are not required advanced functionality of ECL310, there are available DSA HOME with ECL110 which oers basic functionality of substation.
The primary modules allow for the upgrading of the compact module with an additional dieren­tial pressure controller, measuring devices, strain­ers or a heat meter to full all of the supplier’s technical connection requirements.
