P1 Set room temperature
P2 This parameter defines
the runtime for intensive
ventilation. After this time
has expired, the appliance
returns to the previously
applicable fan stage. If
the intensive ventilation
is switched on with an
external switch, this pa-
rameter defines how long
the intensive ventilation
continues to run after
opening the switch.

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
the bypass damper ensures that outdoor air bypasses the heat
exchanger and flows directly into the building.
