Carbon dioxide (CO2) detector with wall installation designed to monitor the air quality
in closed environments such as shops, offices, public places, etc.
It is equipped with two relays that are activated independently when the CO2 concentration
exceeds the threshold value set in the factory and can be used, for example, to activate
ventilation units to force air exchange. The CO2 detector mounted on the device measures,
in addition to the carbon dioxide concentration, also the present temperature and humidity.
The values of these three quantities are associated with as many analogue outputs.
RQAIR is a device of electronic type , designed to perform actions of 1B type and is intended
to operate in environments with overvoltage category III and pollution degree 2, according
to EN 60730-1 standard.

SAFETY WARNINGS
During product installation and operation it is necessary to observe
the following instructions:
1) The device must be installed by a qualified person, in strict compliance
with the connection diagrams.
2) Do not power the device if any part of it is damaged.
3) After installation, inaccessibility to the connection terminals without
appropriate tools must be guaranteed.
4) The device must be installed and activated in compliance with current electric
system standards.
5) Before accessing the connection terminals, verify that the leads are not live.
6) A protection device against over-currents should be installed in the electrical
system, upstream of the device.
7) There must be a bipolar disconnection in the power supply network.
TECHNICAL FEATURES
• Power supply: 230Vac (-15% ÷ + 10%) 50 Hz
• Two relay outputs with 8 (2) A / 250Vac breaking capacity
• 3 LEDs to indicate the concentration of CO2
- Good (green) = CO2 below 800 ppm
- Normal (yellow) = CO2 between 800 ppm and 1200 ppm
- Poor (red) = CO2 above 1200 ppm
• 2 LEDs for indicating the status of the outputs
- Out 1 (red) = on with CO2 greater than 700 ppm
- Out 2 (red) = on with CO2 greater than 1300 ppm
• 3 analogue outputs 0 ÷ 10V isolated:
- CO2 for range 0 ÷ 2000 ppm
- temperature for range 0 ÷ 50 ° C
- humidity for range 0% ÷ 100% Rh
• Dip-switch to select the direct or reverse operating logic of the relays
• Operating temperature: 0 ÷ 50 ° C
• Operating humidity: 30 ÷ 90% non condensing
• Storage temperature: -20 ° C ÷ + 70 ° C
• Degree of protection: IP40
• Insulation: reinforced between accessible parts (front) and all other terminals
DETECTOR POSITIONING
Install the detector at a height of about 1.5-2 m from the floor, avoiding positions with excess
or total lack of ventilation.
Moreover, make sure that the detector is installed away from direct radiation, at a distance
of at least 30 centimeters from doors, windows and heat sources.
Pay attention that the air flow that hits the detector is not obstructed by curtains or
wardrobes placed nearby.
Avoid installing the detector in a humid area or with temperatures outside the operating range.
Moreover, avoid placing the detector near sinks, cooktops or near extractor hoods or vents
and, more generally, areas where dirt and dust could obstruct the air slots, preventing
correct operation.

WIRING DIAGRAM
INSTALLATION
To install the device proceed as follows:
1. remove the detector cover:
unscrew the fixing screw and slightly lift
the right side before sliding it to the left
2. route the power cables, the loads to be
connected to the relays and the analogue
outputs through the central hole
3. make the connections respecting the diagram shown in this user manual
4. choose the operating logic of the relays through the dip-switch DP1
= direct operation, relay contact closed in alarm conditions
= reverse operation, relay contact open in alarm conditions
Warning: carry out the operation only with the device not powered.
Note: the dip-switch DP2 DP3, and DP4 must remain in OFF position.
5. reposition the detector cover, proceeding in the reverse order to removal, taking
care not to bend or crush the leds. Then screw the screw on the right side
to fix the cover.
6. Power up the device and check that the status of the leds and relays is as described
in the “Operation” chapter.
OPERATION
During the operation the detector may be in one of the following status:
• Start-up and configuration detector
For the 2 seconds after switching on, the device remains in an inoperative status,
signaled as follows:
Led

For the next 3 seconds the device remains in an inoperative status where it starts the
detector. This condition is signaled as follows:

• Normal operating status
After the start-up phase, the detector measures the concentration of carbon dioxide in the
room. The status of the leds and relay outputs depend on the CO2 concentration detected:
- CO2 less than 700ppm

CARE AND MAINTENANCE
RQAIR is pre-calibrated in the factory and does not require special maintenance.
However, it is necessary to ensure the cleaning of the air slots on the front of the detector
to ensure proper air flow. Do not use chemicals, polishes or bleach for cleaning.
Simply dust with a damp cloth.
