*) The values must be configured according to the individual capacity graph lines.
1) All control systems integrated in the unit include as a standard feature at least two inputs for connecting electric signals resulting
from human activity such as handling light fixtures or other devices which automatically control the unit’s capacity levels. These
inputs must always be connected; alternatively, other types of sensors must be connected instead (e.g. CO
2
, VOC and RH).
For the detailed design of individual components use ATREA’s selection software.
