3.0 System overview

3.1 General about district heating substations

The heating system of the property is connected to the district
heating network with the substation. Hot district heating water in
the district heating network runs through the heat exchangers in
the substation. District heating water does not enter the internal
network, just heat is transferred through the heat exchanger. The
substation distributes heat into the heating and domestic hot
water circuits.
All substation functions are controlled with an electronic con-
troller. The outdoor temperature is measured and the controller
adjusts the flow temperature to keep the room and domestic
hot water temperatures in the desired level. With the controller
you can change the property related settings (e.g. heating curve,
temperature limits), check the temperatures, change the settings,
create schedules etc.

3.2 DSA 2 MAXI Substation

Up to a certain point DSA 2 MAXI substation is standardized.
The final selection of components and the dimensioning of the
heat exchangers is done based on the requirements given by the
customer. This Installation Guide includes general instructions.
The more detailed information of the order can be found in the
product related documentation.

Warning of hot surface
The substation has got hot surfaces which can cause skin burns.
Please be extremely cautious in close proximity of the substa-
tion.
Warning of high pressure and temperature
The maximum temperature and pressure always have to be
checked on the product data label attached to the product.
Be aware of the installation's permissible system pressure and
temperature. The risk of persons getting injured and equipment
being damaged increases considerably if the recommended
permissible operating parameters are exceeded.
The substation installation is equipped with safety valves which
must always be mounted in accordance with local regulations.
Warning of transportation damage
Prior to installing substation, please make sure that the substa-
tion has not been damaged during transportation. Be extreme-
ly careful when lifting or moving big and heavy substation.
