Symbol Description
Power : This symbol indicates that the appliance is switched on and
the fans are operating in "humidity protection" mode.
Time : This symbol indicates that the appliance is operating in time
program mode. Depending on the program, the appliance is oper-
ated at different fan stages.
Fan : This symbol, with the associated digit, indicates the fan stage
at which the appliance is currently running.
Passive cooling : If the conditions for passive cooling are met, the

This symbol is displayed when the function block is activated. Press
the "HOME" and "OK" buttons simultaneously for two seconds to

Frost protection : This symbol is displayed when the appliance has
turned on the preheating coil for frost protection.

in the event of faults that do not impair the basic function of the
appliance. The "service/fault" symbol flashes if a serious fault has
occurred. Call your qualified contractor.
4.3 Selecting the fan stage
From the home screen, you can use the Touch-Wheel to select fan
stages 0, 1 and 2. The set value is accepted without you having to
press a button to confirm it.
You cannot activate intensive ventilation with the Touch-Wheel.
To switch on intensive ventilation, press the "intensive ventilation"
button for approx. one second. When intensive ventilation is ac-
tivated, the "intensive ventilation" indicator illuminates. You can
activate intensive ventilation with an external switch or with the
"intensive ventilation" button. You can only deactivate intensive
ventilation with the "intensive ventilation" button.
If you set fan stage 0, the appliance switches to a 24 hour dormant
phase. The humidity protection control unit only starts after this.
The qualified contractor can configure the humidity protection
control unit with parameters.
4.4 Activating time programs
The "time" symbol indicates that time programs are activated.
If the time programs are not activated, turn the Touch-Wheel
clockwise to switch from the home screen. After fan stage 2, the
fan stage set in the time program appears along with the "time"
symbol.
Note
If you switch the appliance to time program operation,
time programs must be entered in the "prog" menu. Oth-
erwise the appliance continues to run without a time limit
in set fan stage 2.
Enter the time program settings in the menu.
At times where there is no time program defined, the appliance
runs in set fan stage 2.
