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 specied 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 specied 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 signicantly 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 eciency and reduced pressure loss. In addition to

the standard controller functions, the ECL310
oers 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
oers basic functionality of substation.
The primary modules allow for the upgrading of
the compact module with an additional dierential pressure controller, measuring devices, strainers or a heat meter to full all of the supplier’s
technical connection requirements.
