COMPACT Control System

Clean Air Control

The Clean Air Control function is used in ventilation sys-

tems where the aim is to regulate the airﬂow according to

the content of emission/impurities in the room air.

One VOC sensor (Volatile Organic Compound) is mounted

as standard inside COMPACT Air & Heat units. For COM-

PACT Unit & Top units, the VOC sensor (TBLZ-1-60) is an

accessory and must be ordered separately.

The VOC sensor measures the content of emissions/impu-

rities in % VOC.

When an occupant emits CO

, this creates a proportional

amount of emissions/impurities which are measurable by

the VOC sensor. For an approximate translation of the %

VOC to CO

content, see the diagram.

When the VOC sensor measures contents of emissions/

impurities that are lower than the preset value; the air

handling unit’s supply air and extract air ﬂows are then

equivalent to the preset min. ﬂows. When the VOC sen-

sor instead measures contents of emissions/impurities that

are higher than the preset limit value, the supply air and

extract air ﬂows are variably increased until the preset

value or max. ﬂow is reached.

Example:

800 ppm is equivalent to approx. 30% VOC.

If inﬂuenced by other emissions/impurities in the air, such

as cooking odours, cigarette smoke, etc., the VOC con-

tent increases in relation to the CO

content.
