Auto Sensor operating mode: Automatic operation with sensor control

Auto Sensor activates automatic operation with sensor control to ensure hygienically perfect ventilation when the ambient air is polluted.

The air volumes are set depending on the measurement determined by the sensor. All CO2 and VOC sensors are taken into account linearly (continuously variable). Depending on the humidity sensors' settings, they are taken into account in a linear (continuously variable) or stepped fashion.

If set to stepped, the measured values of all internal and external humidity sensors are taken into account. Connected external air quality sensors (CO2/VOC) are not taken into account.

If ventilation level II (nominal ventilation) is switched on via RLS 1 WR single control unit or EnOcean wireless control unit, the unit always runs in Auto sensor mode if the single control unit is configured to Solo (Combi sensor operation parameter to linear or stepped). CO2/VOC sensors are always taken into account in a linear (continuously variable) fashion.

Demand-based operation (linear)

Parameter Operation combi-sensor = linear

In linear operation, the humidity sensors are controlled continuously between the set minimum values (reduced ventilation) and maximum values (intensive ventilation).

Linear humidity-based control

Use the touchscreen control unit or web server to set the parameters Rel. humidity limit min and max in the Humidity menu and set the parameter Combi-sensor operation to Linear. The system controls the humidity on the basis of values measured with the internal and optional external humidity sensors in a continuously variably fashion.

Setting stepped control as excess humidity protection

Using the touchscreen control unit or WebServer, set the Rel. humidity limit max parameter in the Humidity menu and set the Combi-sensor operation parameter to Stepped . When the switching point is reached, the ventilation unit runs in intensive ventilation until the value is 3 % below the limit value.

Setting linear control to CO2 or VOC

Set the parameter CO2 limit value min and max or the VOC limit value min and max in the Sensors menu with the touchscreen control unit or web server. Based on the values measured with the optional, external CO2 and VOC sensors, the ventilation unit regulates the supply of fresh air continuously.
