1 Safety
1.1 Correct use
The electronic control component type BC0-Compact is
used in combination with a TROX air terminal unit for
variable volume flow rate control in ventilation and air
conditioning systems.
The Compactregler is designed for use indoors to con-
trol clean indoor air.
Supply air area of application:
–The usual conditioning in ventilation and air con-
ditioning systems allows use in the supply air
without additional dust protection measures.
Extract air area of application:
– Extract air with a low content of dust or lint (e.g.,
office) allows use without additional dust protec-
tion measures.
– For dry extract air with a higher proportion of
dust or lint, a suitable filter must be used in front
of the VAV terminal unit.
– For extract air with a high content of dust, lint or
sticky components, or extract air with aggressive
operating fluids, use a TROX controller with a
static differential pressure transducer.
– Do not use VAV terminal units in extract air sys-
tems in commercial kitchens unless the extract
air has been cleaned as much as possible with
high-efficiency aerosol separators; see
VDI 2052.
In unspecified applications, or when combined with con-
taminated air (e.g., dust) and moisture, a TROX con-
troller with static differential pressure transducer should
be used.
Incorrect use
WARNING!
Danger of injury or risk of damage to property
due to incorrect use!
Misuse of the control component can lead to dan-
gerous situations.
Never use the control component/device:
–in explosion-proof areas
– in aircraft
– outdoors without sufficient protection against the
effects of weather
– in humid air (even temporarily, i.e., in wet areas,
such as bathrooms with showers)
– for areas of application that are not described in
this manual
Modifying the unit or using replacement parts that have
not been approved by TROX is not permitted.
1.2 Safety signs
The following symbols and signs are usually found in
the work area. They apply to the very location where
they are found.
WARNING!
Danger due to illegible signage!
Over time, stickers and signs may fade or become
otherwise illegible, meaning that hazards cannot be
identified and necessary operating instructions
cannot be followed. There is then a risk of injury.
– Ensure that all of the safety, warning and oper-
ating information is clearly legible.
–Replace illegible signs or stickers immediately.
Electrical voltage
Only skilled qualified electricians are allowed to work in
areas marked as having electrical voltage.
Unauthorised people must not enter areas, open cabi-
nets or work on components where an electrical voltage
is present and which are hence marked with this
symbol.
1.3 Residual risks
The VAV terminal unit is state of the art and designed in
accordance with current safety requirements. Residual
risks cannot be excluded, however, and you should pro-
ceed with caution. This section describes the residual
risks that have been identified in a risk assessment.
Always follow the safety notes in this manual to reduce
health hazards and prevent any hazardous situations.
