1. Introduzzjoni
The S+S Regeltechnik RCO2-AS NT is a maintenance-free CO2 meter designed to monitor ambient air quality. It features a traffic light LED indicator and an acoustic signal to provide clear and immediate feedback on CO2 levels. This device is suitable for use in classrooms, offices, meeting rooms, hotels, apartments, and retail spaces, enabling energy-efficient and demand-oriented ventilation. This manual provides essential information for the safe and effective operation of your CO2 meter.
2. Prodott Aktarview
The RCO2-AS NT measures CO2 concentration in the range of 0 to 3000 ppm using a high-precision NDIR (Non-Dispersive Infrared) optical sensor. The device features an auto-calibration function, ensuring reliable measurements. Visual indication is provided by five colored LEDs, and an acoustic alarm can be activated or deactivated via a DIP switch.
- LED Traffic Light System: Green (good air quality), Yellow (ventilation recommended), Red (intensive ventilation required).
- Sinjal Akustiku: Sounds when warning levels are reached, can be disabled.
- Mingħajr Manutenzjoni: Designed for long-term, reliable operation without regular maintenance.
- Awtokalibrazzjoni: Ensures accurate CO2 measurements over time.
3. Istruzzjonijiet tas-Sigurtà
- Aqra dan il-manwal kompletament qabel ma tħaddem l-apparat.
- Tesponix l-apparat għal temperaturi estremi, umdità, jew dawl tax-xemx dirett.
- Use only the provided power adapter or a compatible power source as specified.
- Tippruvax tiftaħ jew issewwi l-apparat int stess. Irreferi għal kull manutenzjoni f'idejn persunal kwalifikat.
- Żomm l-apparat 'il bogħod mill-ilma u likwidi oħra.
4. Setup
4.1 Tqegħid
For optimal performance, place the RCO2-AS NT in a central location within the area to be monitored. Avoid placing it near windows, doors, or ventilation outlets where air currents might distort readings. A general recommendation is to use one sensor per 30 m² of floor area.
4.2 Konnessjoni tal-Enerġija
- Connect the plug-in power supply to the device's power input port.
- Ipplaggja l-provvista tal-enerġija f'sokit elettriku standard.
- Upon power-up, the device will initiate a self-test and warm-up phase, which may take a few minutes. During this time, the LEDs may cycle or remain off.
4.3 Kalibrazzjoni Inizjali
The RCO2-AS NT features automatic calibration. For accurate initial readings, it is recommended to operate the device in a well-ventilated area with fresh air for at least 24 hours after the first power-up. This allows the auto-calibration function to establish a baseline for CO2 levels.
5. Istruzzjonijiet Operattivi
5.1 Reading the LED Indicator
The device uses a traffic light system to indicate CO2 levels:
- LED aħdar: Air quality is good. No ventilation is currently needed.
- LED isfar: Ventilation is recommended. Open windows or activate ventilation systems.
- LED aħmar: Intensive ventilation is necessary. High CO2 levels detected, requiring immediate air exchange.
5.2 Sinjal Akustiku
The RCO2-AS NT can emit an acoustic signal when CO2 levels reach the warning (Yellow) or critical (Red) thresholds. This signal serves as an additional alert for users.
5.3 Disabling the Acoustic Signal
The acoustic signal can be deactivated using an internal DIP switch. To access the DIP switch:
- Iftaħ l-apparat b'attenzjoniasing. (Note: This should only be done by qualified personnel or with extreme care to avoid damaging internal components.)
- Locate the DIP switch labeled 'ON' or '1' on the circuit board.
- Toggle the switch to the 'OFF' position to disable the acoustic signal.
- Agħlaq l-apparat casing b'mod sigur.
6. Manutenzjoni
The RCO2-AS NT is designed to be maintenance-free. However, to ensure continued accuracy and longevity:
- Tindif: Imsaħ bil-mod il-barra tal-apparat b'ċarruta ratba u niexfa. Tużax prodotti tat-tindif jew solventi li joborxu.
- Fluss tal-arja: Ensure that the ventilation openings on the device are not obstructed.
- Awtokalibrazzjoni: For the auto-calibration feature to function optimally, ensure the device is exposed to fresh air periodically (e.g., during regular room ventilation).
7 Issolvi l-problemi
| Problema | Kawża Possibbli | Soluzzjoni |
|---|---|---|
| L-ebda LED ma jixgħel | L-ebda provvista tal-enerġija jew konnessjoni difettuża. | Check power adapter and wall outlet. Ensure the power cable is securely connected. |
| Readings seem inaccurate | Device not properly calibrated or placed in an area with poor airflow. | Ensure the device has been exposed to fresh air for auto-calibration. Relocate the device to a more central position away from direct drafts or stagarja kbira. |
| Acoustic alarm does not sound | Acoustic signal is deactivated via DIP switch. | Refer to Section 5.3 to check and activate the acoustic signal if desired. |
| Acoustic alarm sounds constantly | Consistently high CO2 levels or faulty sensor. | Ensure adequate ventilation in the room. If the problem persists after ventilation, contact support. |
