Figure 4 – VCS control unit internal structure
Other controls (technological)
For basic control (triggering, mode switching)
from a technology or a very simple manual button / switch
control, you can use "Other Controls". External control via one
or two non-voltage contacts.
Control from parent system
When integrating HVAC with the VCS control unit into complex
building management systems (BMS), it is also possible to
connect to these systems. Subsequently, it is possible to
control and monitor the HVAC through them. e ModBus,
LON, and BacNet standards can be used.
The different types of control must be designed when
designing (confi guring) VCS into the project and especially in
production - the usability of remote control and connectivity
to the BMS are dependent on the use of the corresponding
controller.
Detailed descriptions of all controller types, control and their
use - see separate sections / chapters of this manual.
Power Part
e power part, like the control part, is always "tailored" for
a specifi c air-handling unit.
