Special extract
Rooms with special needs get their own extract that follows a trigger. Each state – low or high – has its own fan command and actions for supply and extract dampers.
- Trigger from a room switch, binary signal, humidity with setpoint and hysteresis, or AHU operation
- Fan controlled by 0–10 V or percent per state
- Supply and extract dampers set to closed, Vmin, Vmax or auto
- Interlock with the air handling unit and supervision of run feedback, fan fault and airflow deviation
