Note
If you have gloves on, have wet hands or the program-
ming 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 20minutes, 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.
Selection indicator
As you move through the menu and parameter levels, the selection
indicator shows your current position. Either a dark background
appears or the current list entry is highlighted by two lines, one
above and one below.
Circular movement
If you brush a finger clockwise along the recessed scroll wheel,
the highlighting field moves through the list of parameters either
to the right, or downwards if the parameters are arranged ver-
tically. With an anti-clockwise rotation, the highlighter moves to
the left or upwards.
Alongside navigation within the menu structure, the scroll wheel is
also used to set parameters. If you make a clockwise rotation, the
value is raised. With a circular movement anti-clockwise, values
are reduced.
Faster circular motions increase the step magnitude when chang-
ing parameters. Your qualified contractor can determine at what
speed of rotation the step magnitude changes, in the “COMMIS-
SIONING” menu using the “TOUCH ACCELERATION” parameter.
4.1.4 Menu key
The menu key has two functions. If you are on the default screen,
press “MENU” to enter the second level of the menu structure.
There, you have access to the appliance setting options, such as
the input of switching time programs.
If you are not in the highest menu level, tap the menu key to go
back one level.
Note
In the following sections of this document, the abbrevi-
ation “MENU” means you should touch the MENU key.
Note
Tap the keys only briefly to initiate the required action.
If you touch the menu and OK keys for too long, the pro-
gramming unit will not respond.
4.1.5 OK button
With one touch of the OK key, you confirm the selection of the
menu entry highlighted. This brings you into the menu tree on the
next menu level. If you are already at the parameter level, “OK”
saves the currently set parameter.
Example 1
In the third area on the start screen, the currently enabled oper-
ating mode is displayed, for example manual mode. If you want
to change to automatic mode, make a rotation until you reach
the required mode. Then confirm your selection with the OK key.
Only now does the appliance change to the new operating mode.
Example 2
The OK key is used to confirm parameter entries. The newly set
value is not saved until you press “OK”.
Note
In the following sections of this document, the abbrevia-
tion “OK” means you should touch the OK key.
4.1.6 Acoustic signals
A click sound accompanies every user action. Example: A click
is heard every time “OK” and “MENU” are tapped. Furthermore,
the clicking accompanies every step along a menu list activated
by a rotation.
4.2 Operating modes
When the start screen is activated, the current operating mode
is displayed. If you want to select another operating mode, scroll
with the scroll wheel. This takes you through the list of possible
operating modes. The current choice (list entry) is shown in the
shaded selection field. To change the appliance to this new oper-
ating mode, confirm with”OK”.
