In order to set the parameter, you must first make it editable by
pressing the "OK" button. Then you can change the value with
the Touch-Wheel. If you do not press the "OK" button to make the
parameter editable, activating the Touch-Wheel causes the next
parameter to be displayed.
Press the "OK" button to save the set value for a parameter. If you
do not confirm the parameter change with the "OK" button, your
change will be lost.
„P1 : Set room temperature
„
Use this parameter to set the outside temperature from which pas-
sive cooling ensures that outdoor air bypasses the heat exchanger
and flows directly into the building.

„P3 : Passive cooling operating mode „
Options Effect
0 Passive cooling is permanently disabled. Air flows through the
heat exchanger.
1 Passive cooling is enabled. The appliance checks whether a win-
dow contact is connected and activated at X18
2 Passive cooling operates with summer day detection. This option
is set in the delivered condition.
3 Passive cooling operates subject to the extract air temperature.
Passive cooling is only activated when an opened window is de-
tected.
Note
The qualified contractor can set the parameters men-
tioned in the description of this parameter.
P24 : Passive cooling release temperature
P25 : Passive cooling blocking temperature
P26 : Passive cooling hysteresis
P27 : Temperature differential for enabling passive cooling
P3 = 2 : Passive cooling with summer day detection
In order for passive cooling to be enabled, the following must
apply for 2 hours: Outdoor air temperature > Set room temper-
ature + P27
If all of the following conditions are met, passive cooling switches
the appliance to extract air mode.
- Outdoor air temperature < Extract air temperature - P26
- Extract air temperature > Set room temperature
If one of the following conditions is met, passive cooling termi-
nates extract air mode.
- Outdoor air temperature < P25
- Outdoor air temperature > Extract air temperature - P26
- Extract air temperature < Set room temperature
P3 = 3 : Passive cooling subject to extract air temperature
In order for passive cooling to be enabled, the following must
apply for 2 hours: Extract air temperature > Set room temperature
+ P27
This delayed activation is intended to prevent cooling down in
spring and autumn.
If all of the following conditions are met, passive cooling switches
the appliance to extract air mode.
- Outdoor air temperature < Extract air temperature - P26
- Extract air temperature > Set room temperature
If one of the following conditions is met, passive cooling termi-
nates extract air mode.
- Outdoor air temperature < P25
- Outdoor air temperature > Extract air temperature - P26
- Extract air temperature < Set room temperature
„P4 : Reset filter „
f Set this parameter to 1 after changing the filters. The appli- f
ance resets the filter runtime to 0. This parameter is auto-
matically reset to 0.
