• Minimal: Activation of the ventilation stage "Minimal" due to the measured sensor value.
• Intensive: Activation of the ventilation stage "Intensive" due to the measured sensor value.
• Diff: Hysteresis
• Stop time: If the ventilation unit runs at the intensive ventilation stage for longer than 2 hours, the sensor-controlled
ventilation will be interrupted for the set stop time. In case of a setting of 0 hours, the ventilation unit will continue to
run in sensor-controlled mode.
Minimal: 800 ppm
Intensive: 1000 ppm
Diff: 160 ppm
Stop time: 2 h
In order to use this function, at least one air quality sensor must be connected. The sensor-controlled operating function
can only be activated by the VOD timer.
Up to 3 different or same types of sensors can be connected to a ventilation unit with 3 free analogue inputs. The hig-
hest ventilation requirement has priority.
If a room temperature sensor is connected to analogue input AI2 (AIR1/KWL-FTF 0-10V temperature 0-10 V sensor),
only analogue inputs AI3 and AI4 will be available for the air quality sensors.
In order to connect more than 3 sensors to a ventilation unit, the optional signal converter AIR1-SK with 6 analogue
inputs and one analogue output is available. Only the same types of sensor can be connected per signal converter
AIR1-SK.
