It is used:
- For air quality measurement in offices, hotels, meeting rooms and convention centres,
apartments, stores, and restaurants, etc.
- For quantitative evaluation of room air pollution with contaminating gases (cigarette smoke,
body perspiration, exhaled breathing air, solvent vapours, emissions from building members
and cleaning agents)
- For adjustable sensitivity regarding the maximum air contamination to be expected
- For room ventilation as-needed, enabled by air changes only taking place when air is polluted
while conserving energy at the same time.
Room air quality is understood as subjective air quality, felt by human beings with their olfactory
organs. As perception varies from person to person and therefore, air quality is assessed differently, a general definition of criteria for room air quality is not possible.
By linearising and high operating temperatures, the air quality sensor achieves marginal drift
and good stability. The sensor is automatically self-calibrating.
The air quality sensor does not trace the concentrations of individual gases, but assesses the
mixed gas as such, i.e. gas concentrations are not measured selectively. Therefore, it is not
possible to specify gas concentrations by the unit ppm.
Detectable gases: mixed gas, vapours of alcanoles, cigarette smoke, automobile exhaust gases,
exhaled breathing air, combustion smoke (from wood, paper, plastics). In addition, compounds of
alkanes, alkenes, aromats, terpenes, halogenated hydrocarbons, esters, aldehydes and ketones
as well as native VOCs such as terpenes and isoprene are ranking among volatile organic compounds VOC. VOCs also evaporate from chemical products used in construction such as coating
compounds, adhesives, or sealing compounds, furnishing objects, cleaning and care products,
office chemicals and floor carpeting.
The sensor's service life is depending on the type of burden and gas concentration and is more
than 60 months under normal load conditions. The new design implies the alternative to choose
between three sensibility ranges by means of DIP switches, comparable to three measuring
ranges: LOW for low, MEDIUM (default, equivalent to the hitherto existing type of this device) for
medium, and HIGH for high noxious gas contaminations.

AERASGARD ® RLQ - UP
Room air quality sensor (VOC)
with active output, in-wall, panel switch programme
The room air quality sensor AERASGARD ® RLQ-UP is used to determine the air quality and qualitative estimation of room air pollution by diverse gas fractions (e.g. cigarette smoke, exhaled
breathing air, solvent vapours, etc.). Energy conservation is achieved by ventilation of rooms on an
as-needed basis. This in-wall version was developed for users with highest demands in respect of
design, as these sensors are available in line with all current panel switch programmes, e.g.
Busch - Jaeger, Berker, Feller, Gira, Legrand, Merten, Niko and Jung. The sensor's service life is
depending on the type of burden and gas concentration and is more than 60 months under normal load conditions.

Notes
Notes regarding RLQ
- This device may only be used in non-precipitating air without above-atmospheric or
below-atmospheric pressure at the sensor element.
- In the operating mode with current output, the device delivers an output current of either
0...20 mA or 4...20 mA (selectable via jumper). This device is not a transmitter.
- The voltage output is short-circuit proof.
- Applying overvoltage will destroy the device.
- In case of pollution, we recommend cleaning and recalibration in the factory.
- The air quality signal “good“...“bad“ is represented by the output signal 0...10 V.
- The device operating range covers 10...95 % relative humidity respectively 0...50 °C.
Beyond that range, mismeasurements or increased deviations will occur.
- The chemical sensor is a consumable. The lifetime of the sensor depends on nature and
concentration of the pollutant gas burden.
- If this device is operated beyond the specified range, all warranty claims are forfeited.
Air quality is measured through a VOC sensor (metal oxide). Due to its functional principle, the
lifetime of the sensor depends on nature and concentration of the pollutant gas burden.
The sensitive layer of the sensor element reacts with all volatile organic compounds and
is thereby modified in its electrical properties or “exhausted“. This process results in a
displacement of the characteristic curve. Such characteristic curve displacement however
amounts to less than 15 % ⁄ year under normal burden. In measuring air quality, the general
condition of air quality is detected. Whether air quality is “good“ or “bad“ is differently interpreted by each person.
Different pollution burdens and concentrations influence the air quality signal (0...10 Volt) in
different ways. Examples for this are cigarette smoke, deodorant sprays, cleaning agents, or
also various adhesive materials for floor and wall coverings as well as dyestuffs. Increased
burdens e.g. by solvents, nicotine, hydrocarbons, aerosol propellants etc. intensify consumption ⁄ aging of the sensor element. Particularly under high pollutant gas burdens – also during
non-operational idle state periods of the devices (transport and storage) – zero-point drift
will occur. Consequently, this must be corrected at site according to the respective circumstances or basic burdens.
Enclosure Frija
To open the enclosure, set a screwdriver (2.0) in
the groove at centre, press down, and lift up the
bottom frame slightly. Pull top cover forward and
hold it.
Air quality measuring instruments of different manufacturers cannot directly be compared
because of different functional principles, preset basic burdens (zero-point), and permitted
burdens (amplification ⁄ sensitivity). Devices are preset respectively calibrated ­a ccording to
the sensor manufacturer‘s specifications. Here, a zero-point and a final value is determined
and thus a maximum burden. In particular cases, exceeding measuring ranges or excessive
basic burdens on the devices will occur (outgassing floor carpeting, wall paint, etc.). In order
to enable distinguishing different air qualities, devices need to be adjusted by the customer
according to the ­c onditions existing on site that do not correlate to the factory-preset definition range and calibration. Please note that factory calibration is thereby lost and compliance
with technical data can no longer be guaranteed.
Automatic calibration of air quality (default), except for UP
The minimum initial value for air quality is memorized within a period of ca. 4 weeks. After that
period has lapsed, the output signal is standardised to zero-point (1.0 V). The maximum amount
of correction is thereby limited to 1 V ⁄ interval. In this way, long-term drifts and operational
aging effects of the sensor element are completely eliminated.
Manual calibration of air quality, except for UP
Manual calibration can be started independently from the position of jumper J3 by pushing
the button. After connecting the device, a period of at least 2 hours of continuous operation
of the device at „normal“ air quality is to be ensured. Manual calibration of the output signal
to 1 V (zero-point) is started be pressing the button „Manual calibration“ (for ca. 5 seconds).
Preparing for calibration is indicated by a blinking LED. Setting the output to 1 V at actual
ambient conditions follows automatically thereafter. During this phase, the LED is permanently
activated. After calibration is completed, the LED is deactivated.
Putting in operation
Upon energizing the device, a self-test and tempering takes place. Depending on ambient conditions, this process takes 3 to 5 minutes. During that time, the output analog voltage deviates
from the actual measured value.

Individual operation
Connection scheme
The output signal is to be tapped by a measuring instrument. Output
voltage is measured here against zero potential (0 V) of the input voltage!
When several devices are supplied by one 24 V AC voltage supply, it is to
be ensured that all ”positive“ operating voltage input terminals (+) of the
field devices are connected with each other and all ”negative“ operating
voltage input terminals (–) (= reference potential) are connected together (in-phase connection of field devices). All outputs of field devices must
be referenced to the same potential!
