The Digital Solution for Local Heat Supplyand District Heating Networks

AT A GLANCE

SAM DISTRICT ENERGY is a web-based solution formanaging, controlling and optimizing heating andcooling systems. All key data on connected controllers, utility meters and electric actuators are saved atone central location. A gateway is used to log theenergy consumption data and make them available
on the SAM DISTRICT ENERGY platform. Meter IDsand consumption data are clearly assigned to one

2another so that the heat consumption and billing information are logged correctly for every customer.
Making trips to read meters on site becomes a thingof the past. The large amount of logged data allows
you to analyze your local and district heating networks, increase their efficiency and achieve bettersystem transparency.

APPLICATIONS AND MARKETS

Energy suppliers and network operators– Detailed analysis of the district heating networks– Information on water flow times and routes– Reduced operating temperature, resulting inlower fuel cost and CO2 emissions– Data pool for analysis and operational plans

Property management companies and service
providers– Support in configuring, optimizing and monitoring
systems– Assistance in planning service jobs
– Strengthened customer loyalty through improved
service– Early alarm notification in the event of malfunctions

ADDED VALUE

Visual network analysis– Heat map in time-lapse mode
– Dynamic detection of a network’s point ofworst efficiency– Route management– Theoretical and actual hydronic balancing of
the district heating network– Connection of pressure sensors for upstream anddownstream pressures, safety circuits and pumps

Sensor sharing

Network pump control– Fewer sensors (e.g. outdoor sensors) required,shorter mounting times and less corehole drilling– Data exchange between controllers within abranch– Forwarding of demand– Remote switching of pumps (e.g. feed pumps)– Reduced pump output– Control based on differential pressure and/or
control signals issued by heating controllers– Centralized overview– Easy installation thanks to cross communication

Data export to third-party ERP systems– Historical data for documentation, certification
and analysis– Heat consumption of individual meters or entire
branches recorded by virtual devices– Event and alarm tracking– Overview of states and network behavior– Opportunity to create new business models– SAP– Oracle®
– FTP etc.

4Maximum transparency

The bigger picture– Lower temperature in the district heating networkby reducing the safety margin– Fewer network losses– Optimized service– Easy isolation and opening of entire pipeline
sections– Improved utilization of network pumps thanks
to flexible analysis of pressure sensors– Energy limitation

Unlimited scalability

Secondary use– Unlimited number of users– Unlimited number of stations– Integration of existing plants– Integration of stations away from the existing
infrastructure– Individual access authorization for
key account users– Consumption readings in real time
– Export function– Detailed user administration– Active assistance for customer support staff

24/7 customer support– Only one point of contact for both connectivity
and district heating– Alarm management– Remote access saves unnecessary trips to the field5

TOPOLOGY– Browser-based app with responsive
web design (suitable for all devices,e.g. notebooks, computers and smartphones)

AVAILABILITYCUSTOMER SYSTEMS– Link existing systems over web services (API)– Flexible connection to the web portal– Combination of various connections
within a system– Connection of all relevant devices ina station, such as controllers, actuators, heat meters, differential pressure
meters, pumps, safety circuits, doorcontacts etc.
– Versatile use of heat meters, e.g. fortemperature monitoring

TECHNOLOGYACCESS

THIRD-PARTY SYSTEMSSAM DISTRICT ENERGY makes it easier to integrate
third-party systems, e.g. customer servers. Functions
include billing, data management, start-up, protocols and map data. An application programming
interface facilitates the integration of such functions.
– Synchronization of administration data
– Exchange of information excluding personal data
– Integration of ERP system protocols– Network route plans– Location IDs and names– Geographic coordinates

CONNECTIVITY

Three different types of technology are available
to link systems to SAM DISTRICT ENERGY:– DSL– Mobile phone network– SAM-LAN wireless technology
Rental instead of buying– SAMSON offers attractive rental models as partof an all-included service package for the term ofcontract.
– Package solutions are available for connectivity to
the web portal. Gateways and routers with M2M
SIM cards (including data rate) provide a high level of privacy and data security.
