with the safety notes and all instructions in this
②
manual.
The local regulations for health and safety at work
and general safety regulations also apply.

Correct use
CAV controllers of Type EN-Ex are used for con-
stant volume flow control in ventilation and air con-
ditioning systems. They can be used for supply air
and extract air systems in the following areas with
potentially explosive atmospheres:
II 2G Ex h IIC T6 Gb
II 2D Ex h IIIC T80 °C Db
Test certificate
Do not use the CAV controller with an electric
actuator!
Do not use CAV controllers in extract air systems in
commercial kitchens unless the extract air has been
cleaned as much as possible with high-sufficiency
aerosol separators; see VDI 2052.
The installation of air terminal devices in humid
rooms, areas with potentially explosive atmos-
pheres or rooms with dust-laden or aggressive air
has to be assessed for each individual case.
