Gira KNX CO₂ sensor

Gira KNX CO₂ sensor with humidity and room temperature controller Gira E2, pure white glossy

The Gira KNX CO₂ sensor re­li­ably mon­it­ors the tem­per­at­ure, hu­mid­ity and car­bon di­ox­ide con­cen­tra­tion in build­ings, and con­trols meas­ures for main­tain­ing the room cli­mate within the KNX sys­tem. In school­rooms, con­fer­ence rooms, and meet­ing rooms: wherever there are a lot of people, the CO₂ con­cen­tra­tion builds up quickly. Well­being, the abil­ity to con­cen­trate, and per­form­ance are already in­hib­ited at a con­cen­tra­tion of 0.08%. The max­imum value of 0.1%, as re­com­men­ded by DIN 1946, is often ex­ceeded under cur­rent build­ing stand­ards and due to the high dens­ity of build­ing shells.

It there­fore makes sense to auto­mat­ic­ally mon­itor air qual­ity. That job is taken on by the Gira KNX CO₂ sensor. In ad­di­tion to its CO₂ sensor, the device is also equipped with a hu­mid­ity and room tem­per­at­ure con­trol­ler. As a res­ult, when cer­tain lim­its are ex­ceeded, it en­sures that win­dows are opened, fans are switched on, and the heat­ing or air con­di­tion­ing is reg­u­lated for ex­ample. The KNX CO₂ sensor is also suit­able for use in the home, e.g. to pre­vent pos­sible growth of mould in con­ser­vat­or­ies. What’s more: it is the first product of its kind that can be in­stalled flush-​mounted, in keep­ing with the rest of the elec­trical in­stall­a­tion in the design line.

CO₂ sensor for fresh air

The Gira KNX CO₂ sensor meas­ures the car­bon di­ox­ide con­tent in the air across a range from 0 to 2,000 ppm. De­pend­ing upon four freely defin­able lim­its, vari­ous func­tions can be con­trolled via the KNX sys­tem, e.g. open­ing win­dows or switch­ing on fans.

Temperature controller for a constant room temperature

The Gira KNX CO₂ sensor can also be used for single-​room tem­per­at­ure con­trol via the in­teg­rated tem­per­at­ure con­trol­ler with in­di­vidu­ally ad­justable set­points. The con­trol­ler dif­fer­en­ti­ates between the op­er­at­ing modes of Com­fort, Standby, Night, Frost/heat pro­tec­tion and Con­trol­ler lock-​out, each with their own tem­per­at­ure set­points in heat­ing and cool­ing mode, and trans­mits the ap­pro­pri­ate cor­rect­ing vari­ables to the heat­ing or air con­di­tion­ing sys­tem via the KNX sys­tem.

Humidity sensor for the prevention of excessive humidity

The in­teg­rated hu­mid­ity sensor de­term­ines the re­l­at­ive hu­mid­ity within a meas­ure­ment range of 10% to 95%. De­pend­ing upon two ad­justable lim­its and the cur­rent hu­mid­ity, vari­ous func­tions can be con­trolled via the KNX sys­tem, for ex­ample open­ing win­dows or switch­ing on fans. In ad­di­tion, the com­bin­a­tion of cur­rent room tem­per­at­ure and meas­ured hu­mid­ity en­ables the Gira KNX CO₂ sensor to de­term­ine the tem­per­at­ure at which water in the air will form con­dens­a­tion on walls and ceil­ings, thus pro­mot­ing the growth of mould. If this tem­per­at­ure point, the so-​called ‘dew­point’, comes close to being reached, the Gira KNX CO₂ sensor can reg­u­late the heat­ing or vent­il­a­tion, for ex­ample, and can also emit an alarm mes­sage via the KNX sys­tem.

Button interface with free function assignment

The device fea­tures a but­ton in­ter­face with two in­de­pend­ent chan­nels which can be locked dur­ing op­er­a­tion. When one of the con­nec­ted switches or but­tons is ac­tu­ated, it sends sig­nals to the KNX sys­tem. These could in­clude sig­nals for switch­ing/press­ing, dim­ming or blind con­trol. In ad­di­tion, it is pos­sible to pro­gram en­coder func­tions such as dim­ming en­coders and light scene aux­il­i­ary units.

Various operating modes

The device can be eas­ily ad­ap­ted to the room con­di­tions thanks to five op­er­at­ing modes – Com­fort, Standby, Night, Frost/Heat pro­tec­tion and Con­trol­ler lock-​out (e.g. dew-​point mode).

Installation

The Gira KNX CO₂ sensor is the first product of its kind that can be in­stalled flush-​mounted in keep­ing with the rest of the elec­trical in­stall­a­tion in the design line. Power is sup­plied via a KNX line, mean­ing that an sup­ple­ment­ary power sup­ply is not re­quired. The KNX CO₂ sensor does not have any op­er­at­ing or dis­play ele­ments.
