¨n General
¨¨n Temperature sensor
If you want the current room temperature and room humidity to
be displayed, you can enable the programming unit's internal
temperature sensor with this parameter. We recommend en-
abling this parameter only if an external programming unit is
connected.
¨¨n Environment sensor
If you require demand-dependent ventilation, activate the CO
VOC sensor with this parameter. If the air quality is poor, the
appliance increases the air flow rate. We recommend enabling
this sensor only in external programming units.
¨n Air flow rate
u Use parameters "Flow rate, stage 0" to "Flow rate, stage 3"
to set the air flow rates for the individual fan settings.
Flow rate, stage 0
m³/h
Flow rate, stage 1
m³/h
Flow rate, stage 2
m³/h
Flow rate, stage 3
m³/h
¨n Offset setting
Use these parameters to match the air flow rates to fan settings
during commissioning.
Calculate automatically
Offset supply air flow rate level 2
Offset extract air flow rate level 2
Offset supply air flow rate level 0
Offset extract air flow rate level 0
Offset supply air flow rate level 1
Offset extract air flow rate level 1
Offset supply air flow rate level 3
Offset extract air flow rate level 3
In parameter "Calculate automatically", if you select the "On"
option, the supply air flow rates and extract air flow rates are
calculated internally for all fan settings on the basis of the stage
2 offset. Alternatively, you can enter an offset value individually
for each fan setting.
Formula for calculating internal air flow rates
Internal supply air flow rate, stage 0 = offset supply air flow
rate, stage 0 + supply air flow rate, stage 0
Example of automatic calculation
Nominal supply air flow rate (stage 2)
Offset supply air flow rate stage 2
This example shows the automatic calculation of the internal set
air flow rates on the basis of the offset for stage 2.

¨n Humidity prot.

¨¨n Enable humidity control
With humidity-dependent flow rate control, the air flow rate is
increased or decreased depending on the humidity level.
Option
Off
On
¨¨n Humidity prot. Interval
If you set fan setting 0, the appliance switches to a 24 hour
dormant phase. Only after this will humidity protection control
start. The appliance measures the humidity of the extract air for
the period set at "Humidity capture delay". The unit compares
the last measured value with the limit value set at "Humidity
threshold". If the humidity threshold value is exceeded, the unit
starts to ventilate. If the humidity threshold value is undershot
again, the unit terminates ventilation. At this point, the humidity
protection interval starts again, at the end of which the moisture
is measured.
¨¨n Humidity threshold
u Set the upper limit for humidity here.
¨¨n Humidity capture delay
The appliance measures the humidity of the extract air for the
set period. The unit compares the last measured value with the
limit value set at "Humidity threshold".
¨n Heat recovery bypass
¨¨n Set room temperature
Use this parameter to specify the outside temperature above
which the outdoor air bypasses the cross-countercurrent heat
exchanger by being routed through the bypass damper and dir-
ectly into the building.
u Select the preferred set room temperature using the Touch-
Wheel.
u Press "OK".
¨¨n Operating mode heat recovery bypass
Option
Effect
Disabled
Bypass mode is permanently disabled. Air
flows through the cross-countercurrent
heat exchanger.
Bypass/window
Bypass mode is active. The air flow by-
contact
passes the cross-countercurrent heat ex-
changer.
The "Bypass mode" symbol appears on the
display.
Outdoor air routing
Bypass mode operates with summer day
automatic
detection. This option is set in the de-
livered condition.
The "Bypass mode" symbol appears on the
display.
