3.3.3 Parameter levels
On the parameter levels, you can change
parameters that have been released by the
configuration. The heating controller differen-
tiates up to 3 parameter levels, depending
on the system code number. These parameter
levels are indicated by PA1, PA2 and
PA-SYS. The indices 1, 2 and SYS match the
indices used on the info levels and the config-
uration levels, i.e. index 1 for the heating sys-
tem, index 2 for the drinking water heating
system and the index SYS for system
functions. The parameters are marked by a
combination of display symbols. Refer to
Appendix B for an overview. The most impor-
tant parameters, such as date, time,
times-of-use or the heating characteristic can
be changed using the control switch. The
operation with this switch is described in
Quick Guide KA 5431 EN. You can only
change parameters on the parameter levels
when you know the code number.
For start-ups, you should change the parame-
ters in the parameter levels because only
here all parameters can be accessed.
If you want to change parameters, proceed as follows:
1. In Appendix B, look for the required
parameter symbol(s), noting the index of
the parameter level!
2. Access the COPA level and then the
required parameter level PA1, PA2 or
PA-SYS as described under ‘Opening a
parameter level’!
3. Change the parameter(s) as described
under ‘Changing a parameter’!
4. Exit the COPA level as described under
‘Exiting the configuration level’!
Opening a parameter level (from the INFO level)
Set the control switch (A) to this
symbol.
Press the arrow key until the display indi-
cates COPA. This is the gateway to the
configuration level.
Press the enter key. NR and 0 appear in
the display. Here, you are expected to
enter the code number.
Use the arrow keys to set the code
number.
NOTE: The longer you press the arrow
keys, the faster the display changes.
Acknowledge the code number with the
enter key. PA1 appears in the display.
Continue to press the arrow key until
parameter level PA2 or PA-SYS appears
in the display!
Press the enter key! The level you selected
is opened. The first parameter appears.
