6.4.16 ReCO
2
The ReCO
2
function is designed for ensuring the correct
air quality or air temperature, by means of recirculating
extract air and minimizing the infl ow of outdoor air.
The function can be used in ventilation systems in which recircu-
lated air intermixture is acceptable.
The function presupposes that the outdoor air damper and the
damper in the air recirculation section are equipped with modu-
lating damper actuators.
Lower outdoor air and exhaust air fl ows as well as lower extract
air fan speed enable the unit to consume less power. A separate
air quality sensor continuously measures the air quality of the
ventilation system.
The pressure drop across the rotor must then be calibrated to
establish a reference pressure drop for the function. Calibration
is put into effect by setting Calibration to the On position.
For more information, see the ReCO
2
function guide.
