methods】
In the following pages you will find how to connect different system applications to this heat
pump, based on your system design. It is of course many ways to do this and it is impossible
tocover every possible system design in the market. We therefore use the following as our
standard applications that is safe, workable and that we recommend. Other applications and
settings for this is possible, but we leave this design to the installer, according to his knowledgeand
understanding of this specific unit menu and possible settings. It is some basic specifications
that applies for all system drawings which is highlighted, and that we ask you read carefully when
considering which system application to use.
-Sensor locations
-System with or without buffer tank
-Internal and external water pump
Sensor locations applies differently for different applications. As a general standard, please refer
to the following.
Sensor locations applies differently for different applications. As a general standard,
please refer to the following.
Without buffer tank: For more stable running of the heat pump, we suggest to place the
sensors on the return line and adjust the heating curve or cooling
temperature accordingly, to fit the normal Delta T for your heating/
cooling system.
With buffer tank(s): For more stable running of the heat pump, we suggest to place the
sensors in the buffer tank(s). As general standard, you should place the
heating sensor in the upper part and cooling sensor in the lower part.
Circulation pump: This unit has a built in circulation pump that makes it possible to
connect the unit directly to a heating system using the internal
circulation pump to circulate the water in the heating system. For bigger
system or in systems with too big pressure drop, the capacity of the
internal water pump is not enough, and a secondary water pump for the
system is required. An external water pump can be controlled by the
heat pump. Please refer to the following pages for different system
applications.
Observe! It is always the installer's responsibility to control that the pressure drop in the
heating system is not higher than the internal circulation pump can handle.
