Siemens Climatix S300 HRV - 5 Application functionalities; 5.1 Application use cases

5 Application functionalities
5.1 Application use cases
The application can be operated in two different use cases that
1. HRV system as the only influence on air flow:
Characteristics:
● Changes in fan speed have a direct influence on the air flow in the multiple
rooms.
● The fan speed is depending on fan speed control, special fan speed control,
temperature-, humidity- and air quality control.
● Commonly used with linear fan speed or air flow control.
Advantages:
● This configuration allows the full functionality described in chapter
"Configuration [➙25]".
2. Independent secondary controls maintain dampers or VAV boxes:
Characteristics:
● Changes in fan speed might have no influence on the air flow in the rooms, as
they can be compensated by the secondary controls.
● Commonly used with HRV duct pressure control.
Advantages:
● The influence of the room conditions on the HRV air flow can be limited
depending on the system’s functionality.
● 4 modes are available, in which the available functions and thus control
choices vary from mode to mode. For example, mode 4 can be selected for
VAV supply and extract:
Secondary control / Function Mode 1 Mode 2 Mode 3 Mode 4
