4.1.3 Scroll wheel
D0000064710
The scroll wheel consists of a touch-sensitive sensor. There is a
key to the left and another to the right of it.
Note
If you have gloves on, have wet hands or the programm-
ing unit is damp, this impedes the recognition of your
touch and the execution of the action you require.
In the „COMMISSIONING“ menu, your qualified contractor can set
the touch sensitivity using the „TOUCH SENSITIVITY“ parameter.
Activation
The user interface is blocked to protect the appliance from acci-
dental incorrect adjustments.
Touch the menu button for 3 seconds to enable the user
interface.
If the scroll wheel and keys are not used for 20minutes, the pro-
gramming unit is locked again. With the function block, you can
block the user interface for 60 seconds.
Once the programming unit is activated, you have two adjustment
options:
- You can select operating modes with the scroll wheel.
- You can press „MENU“ to continue navigating from there to a
specific appliance parameter.
