WHAT IS CO EQUIVALENT
2
When we talk about air quality, we usually mean the concentration
of carbon dioxide present.
However, it is established that there are, in addition to carbon dioxide (CO
also other gases responsible for the decay of air quality and, consequently,
of the greenhouse effect: methane (CH ), protoxide nitrogen (N
4
hydrofluorocarbons (HFC), perfluorocarbons (PFC) and sulfur hexafluoride (SF
Each of these gases contributes to the greenhouse effect with a different
weight (called GWP or Global Warming Potential).
The measurement of all these gases that also takes account
of their specific GWP is called CO equivalent (CO

such as shops, offices, public places, etc.
The output relay is activated when the equivalent CO2 concentration exceeds
the intervention value set with the knob, and can be used, for example,
to activate ventilation units for air exchange. The device performs actions
of 1B type and is intended to operate in environments with pollution degree 2
and overvoltage category III (EN 60730-1).

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 or connect 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
systems standards.
5) Before accessing the connection terminals, verify that the leads are not live.
6) In the electrical system of the building where the instrument must be installed,
a protection device from the overcurrents must be present.

INSTALLATION
• Install the device at a height of about 1.5-2 m from the floor, avoiding positions
with excess or total lack of ventilation. Also 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 flow of air 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. Also avoid positioning the detector near sinks, hobs
or near extractor hoods or vents and, more generally, areas where dirt
and dust could obstruct the slots, preventing correct operation
• The device is sold already mounted with anthracite colour.
To transform it in the white version, remove the knob and the cover, acting
on the hooks placed on the upper and lower side of the device and mount
the cover and the white knob included in the package.

OPERATION
Start up
After powering up, the device performs the starting phase, which is
necessary to warm up the detector. In this phase, which lasts a total of about
20 seconds, the red led flashes and in the initial 2 seconds the relay switches
twice. In this phase the device does not perform any adjustment and the relay
remains between terminals 2 and 3.
After the starting phase, the device performs the detector self-calibration.
This phase has a variable duration, from about 30 minutes in the best case
(which occurs if the room is well ventilated, with a CO
about 400 ppm) up to 8 hours in the worst case. During the self-calibration
phase, the adjustment is still active, even if the CO
out by the detector can take place with lower accuracy.
Note: the starting and self-calibration phase are performed every time
the device is powered.
Setpoint modification
• Use the selector placed on the front to turn on or off the device:
- position 0: device off, no regulation
|
- position : device switched on, active regulation.
• Use the knob to set the intervention value.
It's possible to set values between 400 ppm and 2000 ppm.
When the CO concentration present in the room exceeds the set value,
2
the red led lights up and the relay switches between contacts 1-2.
Note: in order to preserve the life of the system, the minimum time
between a relay switching and the next one is 1 minute. However, the led
status updating is immediate. Therefore, after using the regulation knob, it
is possible to find a momentary discrepancy between what is indicated by
the led and the actual status of the relay.
This condition lasts for up to 1 minute.
Reduction of the adjustment range
It is possible to mechanically limit the adjustment range if the device
is installed, for example, in public places or in hotel rooms.
To limit the adjustment range, proceed as follows:
- position the knob in an intermediate value to the desired range
(for example, if the desired adjustment range is 1000-1600 ppm,
bring the knob indicator to the 1300 ppm position)
- remove the knob.
- under the knob there are two rings marked from the words "min"
and "MAX", respectively for the lower limit and above.
- turn the "min" ring nut clockwise
and position it at the minimum
value of the desired adjustment
range (refer to the ppm values
shown on the cover).
- turn the "MAX" ring nut
anticlockwise and position
it corresponding to the
maximum value of the
desired adjustment range
(refer to the ppm values shown on the cover).
- reposition the knob, making sure that the indicator of the setpoint on
the knob is in the same position as when the knob has been removed.
To remove the setpoint limitation, turn the two ring nuts until the limitation
blocks are in an external position in the range 400 ppm ÷ 2000 ppm.
Probe error signal
The device signals the probe error condition with the LED flashing.
In this case the regulation is inhibited and the relay contact remains
between terminals 2 and 3. Contact Vemer Technical Support.
CARE AND MAINTENANCE
Fiuto does not require any particular maintenance.
However, it is necessary to ensure the cleanliness of the slots placed
on the front to ensure proper air flow. Do not use chemicals, polishes
or bleach for cleaning. Simply dust with a damp cloth.
