The recommended installation height for the room sensor AIR1/KWL-CO2 0-10 V
is between 1.4 and 1.5 m, persons who are usually standing and sitting are con-
sidered equally at this height.
The room sensor AIR1/KWL-CO2 0-10 V can also be installed at a different height
if the specific spatial conditions do not allow the recommended installation height.
