4�1�3 Sensor-controlled operation (VOD - Ventilation on demand)
The sensor-controlled operation function (Ventilation on demand = VOD) must first be set in the commissioning
assistant.
The sensor-controlled operation only works in "Constant volume flow mode" or "Constant speed mode". The sen-
sor-controlled operation function can only be activated using the VOD timer.
The sensor-controlled operation is only used to achieve improved room air quality. In this respect, the use of air quality
sensors (KWL-CO2 0-10V, KWL-FTF 0-10V, KWL-VOC 0-10V) is required. This mode can also be used for
multiple connected sensors. A signal converter (AIR1-SK) must be used if more than 3 sensors are to be
connected. The sensor with the highest ventilation requirement determines the ventilation operation mode.

• Reduced: Activation of ventilation stage "reduced"
• Boost: Activation of ventilation stage "boost"
• Diff: hysteresis
VOD stop time: As soon as the ventilation unit has been operating at the "boost" ventilation stage for longer than 2
hours, the sensor-controlled operation will stop for the set overrun time. 0 hours means that the sensor-controlled
operation will not stop due to a high sensor requirement.

4�1�4 Recirculation
All extract air is returned to the supply air in recirculation mode.
A separate temperature setpoint and fan offset are available in recirculation mode.
The commissioning assistant must first be activated in order to use the ventilation mode.
Settings for the ventilation mode:
• Log on as User or Admin
• Call up the "Temperature" menu
• Set the setpoint (temperature) for recirculation
• Set supply air fan offset (deviation)
