5.5 Smoke extraction operation
The KUBAIR F400 ECOWATT
®
is approved for extraction of hot gases and smoke in the event of a fire.
This mode of operation is automatic and does not require any setting: In the case of extraction of gas at a
temperature > 200°C, the roof fan will automatically switch to high speed with its internal thermal protec-
tions inhibited.
The smoke extraction mode must be triggered manually with a BDRA type control unit.
The CAV/VAV/COP modes are no longer accepted.
