MOUNTING ADVISE ROOM SENSORS
The accuracy of the room sensors are influenced by the technical specifications as well as the positioning and the installation type.
During Assembly:
- Seal mounting box (if present).
- Installation type, air draught, heat source, radiation heat or direct sunlight can affect the measurement.
- Building material specific properties of the installation place (brick-, concrete-, partition wall, cavity wall, ...) can affect the measurement.
Assembly not recommended in...
- Air draught (e.g.: close to windows / doors / fans ...)
- Near heating sources,
- Direct sunlight
- Niches / between furniture / ...
APPLICATION NOTICE FOR HUMIDITY SENSORS
At regular environmental conditions, it is recommended to calibrate the sensor annually to check the compliance with the accuracy required in the application. The following conditions can damage the sensor element or lead in long term to loss of the specified accuracy:
- Mechanical stress
- Contamination (e.g. dust / fingerprints)
- Aggressive chemicals
- Ambient conditions (e.g. condensation on measuring element)
Re-calibration or exchange of the sensor element are not subject of the general warranty.
i Do not touch the sensor elements!
INFORMATION ABOUT SELF-CALIBRATION FEATURE CO2
All gas sensors are subject to drift. The degree of drift is dependent on the use of components and product design. In addition, the following environmental conditions, among others, can accelerate/favor the aging and wear of the sensors:
- Mechanical stress (also due to temperature fluctuation)
- Contamination (dust / fingerprints e.g.)
- Abrasive chemicals
- Environmental influences (high humidity / condensation on measuring element)
An internal self-calibration function with dual channel technology compensates the caused drift. Thermokon sensors are for permanent use (e.g. hospitals).
INFORMATION ABOUT INDOOR AIR QUALITY CO2
EN 13779 defines several classes for indoor air quality:
Category | CO2 content above the content in outdoor air in ppm | Description |
---|---|---|
IDA1 | Typical range <400 ppm | Standard value |
IDA2 | 400.. 600 ppm | Good indoor air quality |
IDA3 | 600..1.000 ppm | Standard indoor air quality |
IDA4 | >1.000 ppm | Moderate indoor air quality |
1.200 ppm | Poor indoor air quality |

MOUNTING ADVICES
The installation can be performed on the flat wall surface or on a flush-mounted box. A representative place should be selected. Sunshine and draft, e.g. in the installation tube should be avoided, so that the measurement result is not falsified. Seal the end of the installation tube.
- For wiring, the upper part of the device must be removed from the base plate. Base plate and upper part are detachably connected to each other by means of locking lugs.
- The mounting of the base plate on the flat wall surface is done with rawplugs and screws.
- Finally, the device is attached to the base plate and fixed with the screw.

FUNCTIONAL DESCRIPTION NOVOS OCC
The sensor lens divides the detection area in 32 measurement areas. The sensor detects changes in infrared radiation that occur when an object* (or person) moves that has a different IR temperature than its surroundings.
Object properties:
- Temperature difference (between object and environment) > +4°C
- Object-speed > 1,0 m/s
- Object-size > 700x250 mm
i The motion detector should not be mounted near disturbing heat sources (e.g. lamps, radiators, fans etc.) to avoid false alarms:
Fast temperature changes on the environment can trigger false alarms.
DETECTION RANGE (NOVOS 3-OCC)
Detection range: 5 m max.
Field of view horizontal: < 90° / 110°
Field of view vertical: < 90° / 110°
Detection zone: 32
An detection distance of 2,5 m results in a square detection zone of approx. 5 x 5 m, or a circular detection zone of approx. Ø 7 m divided in 32 measuring zones.
Formula: tan(field of view/2)*detection distance =Radius detection range
* The specified ranges refer to average conditions and are approximate values.
Function test
A function test ensures that a movement is located in the optical detection area of the sensor. Walk through the detection area after integrating the device in a LoRaWAN® Network and check whether a radio telegram was send.
