Multi-functional DC inverter air/water heat pump
GB
For the fi ve diff erent operating modes (see chapter 2 “System description“),
there is a variety of hydraulic integration options.
For the space-cooling modes, all water-carrying components must be insulated
impermeably and protected against corrosion.
The following application examples are only schematic diagrams. They must be
complemented by missing safety modules etc.
The safety-related equipment for DHW heating systems must be installed according to
DIN EN 12828.
In all systems the minimum volume fl ow in the heating circuit of the heat pump must be
adhered to. Non-observance can lead to failure.

The heat pump is equipped with a wired electronic control unit.
The control unit is installed inside the house. In order to avoid interferences, the connection
cable of the control unit should not be laid close to the main connection line.
You can request a variety of information from the control unit. Furthermore, users and
technicians are provided with all setting options required.
The control unit is used during installation and maintenance.
Under normal circumstances, the control unit does not need to be accessible for residents.
OEG heat pumps are equipped with high-quality components to avoid and reduce sound
emissions. However, operating noise cannot be entirely avoided. Depending on the
installation location and pump model, the following minimum clearances towards sensitive
areas (e.g. bedroom windows) are recommended for the operation during the night.
