AERASGARD RFTF - CO
The maintenance-free microprocessor-controlled AERASGARD
is used to detect the CO content in air within a range of 0 ppm to 2000 ppm CO
2
The measurement signals from the CO
signals of 0 -10 V. Optionally, this CO
switching output.
Elegant enclosure made of plastic, with snap-on lid, base with 4-hole attachment for
installation on vertically or horizontally installed in-wall flush boxes, with predeter-
mined breaking point for on-wall cable entry, or in enclosures made of stainless steel
(top and bottom part are of stainless steel, the lid is screwed on), vandalism-secure
version e.g. for schools, military barracks, and public buildings.
The CO content of air is determined by a dual beam NDIR sensor (non-dispersive
2
infrared technology). The detection range of this CO
ard applications such as monitoring of residential rooms or conference rooms. Room
ventilation on an as-needed basis, improvement of well-being and customer benefit,
increased comfort as well as a reduction of operating costs by energy conservation
are only some of the beneficial results of employing AERASGARD

is selected via two switching thresholds,
which are set at two potentiometers:
Lower limit via S1 (0 V), upper limit via S2.
At the RTM - CO - 2S the operating mode

can be changed via pushbutton:
Automatic, Manual (Step 1 and Step 2), and OFF.
