Weighted mean value sensors F1 and F2
This theoretical mean value from sensors F1 and F2
may be useful for the control circuit or display. It is
calculated as follows:
= (
x
+ (100 -
) x
) / 100

Calibration of sensor F1…F4
actual value correction
With this parameter it is possible to correct actual
value deviations caused by sensor tolerances, very
long sensor cables or structural protections (e.g. ex-
barriers), for example. The value defined here is added
to the measured value.
,
,
,
Weighting factor F1…F4
With this parameter, it is possible to correct actual
value deviations due to unfavourable sensor location.
The value measured by the controller is multiplied by
the value set here.

,
,
Sensor selection F1…F4
With this parameter, you can define the sensor type.
Depending on the hardware, not all sensor types may
be supported. For the NTC sensor, a parallel resistor
will have to be connected.
,
,
,
Software filter F1…F4
In this parameter, you can define how many measured
values are to be used for calculating a mean value. A
mean value is calculated from the last measured
values, with the oldest measured value being deleted
(so called "Moving Average Filter").

F1…F4: Display at 0 / 4mA
If, when choosing the sensor,
/
/
/
=
7 or 8 is selected (0…20mA or 4..20mA linear sensor),
you can define via this parameter which value is to be
displayed in the case of a current of 0 or 4mA. The
value to be displayed for 20mA can be defined in the
next parameter. The actual measured value is
calculated as linear interpolation between these two
values.

F1…F4: Display at 20mA
If, when choosing the sensor,
/
/
/
=
7 or 8 is selected (0…20mA or 4..20mA linear sensor),
you can define via this parameter which value is to be
displayed in the case of a current of 20mA. The
display value for 0 / 4mA is defined in the previous
parameter. The actual measured value is calculated as
linear interpolation between these two values.
Weighting of sensor F1 for display
(weighted mean value of sensor F1 and F2)
This theoretical mean value from sensors F1 and F2
may be useful for the control circuit or display. It is
calculated as follows:
= (
x
+ (100 -
) x
) / 100
Password for parameter level
This parameter sets the password for level
.
Pre-defined parameter

(password-protected)
Internal: active data set
With this parameter, you can set up pre-defined data
sets. The data sets are provided by Störk-Tronic. If a
new data set is loaded, all previously set parameters
will be overwritten. After that, they can be edited as
required.
Password for accessing level selection
With this parameter, you can set the level selection
password, i.e. in display
. In the standard design,
access to level selection is blocked by password
.
This parameter cannot be set on the controller itself
but only via the ST-bus.
Password of parameter level
With this parameter, you can set the password for
parameter level
.
Networking and
display
(password-protected)
ST-bus own address
With the address set here, the controller can be
addressed via the bus. Each bus client must have its
own address. Addresses must be unique, i.e. must not
be assigned several times.
Temperature scale
With this parameter, you can define if temperature
values are to be displayed in °F or °C.
Display mode
Here, you can switch over between 3-digit and 4-digit
display. However, if the hardware provides 3 digits
only, the left digit will be lost, i.e. the sign in the case of
negative numbers. You can also define here if values
are to be displayed without decimal places, with
rounded decimal place or exactly.
