INSTALLATION
Settings
COMMISSIONING
 PROGRAMMING UNIT
 TOUCH SENSITIVITY
This parameter enables you to select the touch sensitivity of the
scroll wheel. Example: You can reduce the sensitivity if large fin-
gers are used or firm pressure. For this, increase the value of the
parameter.
 TOUCH ACCELERATION
Faster circular motions increase the step magnitude when chang-
ing parameters. With the "TOUCH ACCELERATION" parameter you
can determine at what speed of rotation the step changeover oc-
curs.
 TERMINAL ADDRESS
Up to four programming units can be connected to the appliance.
However, this includes the programming unit built in at the factory
and the Internet Service Gateway that can be connected as an ac-
cessory. If more than one programming unit has been connected
to the appliance, assign each one an individual, unique "TERMINAL
ADDRESS" in the "COMMISSIONING" menu.
If the terminal addresses were not assigned, there would be con-
flicts in communication between the appliance and the program-
ming units, as every programming unit is given the same standard
value for the terminal address parameter.
The internal programming unit has terminal address4 as stand-
ard.Programming units to be used for room temperature and hu-
midity sensing must be given terminal address 1 or 2.
 HC ROOM T DETECTOR
If the programming unit is integrated directly in the appliance,
this parameter does not appear.
If a second programming unit is connected, after being enabled
during commissioning, the system prompts for the assignment of
a heating circuit. Select "HC1" to assign the programming unit to
heating circuit1 or "HC2" accordingly. If you select "NONE", the
actual room temperature will not be taken into account when
controlling the appliance, and the programming unit will work
only as a remote control.
 CONTROLLER
 DELIVERED CONDITION
If you give this parameter the value "ON", then all parameters
will be reset to their factory settings. All changes made will be
lost. Even the appliance type will need to be re-entered under the
"Appliance type" parameter.
The delivered condition only loads the default values; it does not
reset any component.
 APPLIANCE TYPE
You can set the appliance type here.
Note
Changing the "APPLIANCE TYPE" parameter can result in
incorrect functioning of the appliance; it must therefore
be changed only by our service department. Therefore
this parameter can only be changed after entering the
customer service code.
The appliance type must be re-entered after the delivered con-
dition has been reinstated or after a new PCB has been fitted.
CONTRACTOR
ENTER CODE
When the numerical contractor code is entered here, all contrac-
tor parameters of the appliance become freely accessible. At the
factory, the "CODE" is set to 1000.
If the customer service code is entered at this point, further pa-
rameters reserved for service department become accessible.
Note
If there is no operating action after a certain period of
time, the control disables access to the protected param-
eters. In that case you will need to enter the contractor
code again.
FAULT SEARCH
 FAULT LIST
The appliance records the faults that have occurred in a circular
memory. The programming unit shows the ten most recent entries
in the fault memory. If one fault occurs several times, it will only
be recorded in the fault list on its first occurrence.
 DELETE FAULT MEMORY
If you set the option "ON" in this parameter, the fault list is cleared.
 STOP EVENT
All actual values and switching states of the appliance are re-
corded in a circular memory. With "STOP EVENT", the recording
stops and it may be possible to draw conclusions from it as to the
cause of the fault.
SWITCH ON MANUALLY
Here, you can switch appliance components or functions on man-
ually. To do so, you have to enter the customer service code.
