Parameter description
J--
Predefined parameter sets
(password protected)
J1
Internal: active data set
This parameter is to set certain predefined
data sets. These are preset by Störk-Tronic.
If a new data set is imported, all previously
set parameters are overwritten. They can be
changed freely afterwards. The data set can
also be changed via the ST-Bus, provided
that it has been enabled via
L42
.
J2
Parameter Reset
With this parameter the parameters of the
current parameter set (see
J1
) can be reset
to their default settings.
To determine the value of the parameters to
be reset, the values of the following bit mask
must be added.

Passwords
Depending on the set bit, the correspond-
ing parameters are reset to factory settings,
depending on the current parameter set (ac-
cording to
J1
).
In order for this function to work, a release
must be triggered with parameter
L42
=1.
Generally not volatile parameters such as
T10 are not deleted!
J98
Password for accessing level
selection
With this parameter, you can set the level
selection password, i.e. in display
PA
. In the
standard design, access to level selection is
blocked by password
-19
. This parameter
cannot be set on the controller itself but only
via the ST-bus.
J99
Password of parameter level
J--
The access to the parameter group
J--
is
blocked with the password -19 in the stan-
dard version.
L--
Networking and display
(password protected)
L0
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.
L2
Temperature scale
Here, you can define if temperature values
are to be displayed in °F or °C.
L3
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 num-
bers. You can also define here if values are
to be displayed without decimal places, with
rounded decimal place or exactly.
L4
Display value
Here, you can define which actual value is
to be displayed. This refers to the display in
normal operation. You will have to leave the
parameter level in order to see the set value.
Possible values which can be set via this
parameter:
L4

1
Cold store temperature
2
Evaporator temperature
3
Cur. control value for evaporator fan
4
Current setpoint cold store, circuit 1
5
Condenser temperature (pressure?)
6
P-control result for condenser fan
7
Cur. control value for condenser fan
8
current setpoint of condenser
9
Cold store temperature via test bottle
function
10 MIN value of cold store temperature
since last reset
11 MAX value of cold store temperature
since last reset
12 Act. value control circuit 2
13 Current setpoint control circuit 2
L6
Software version
Here, the software version of the controller
is displayed.
L7
Display in standby mode
In this parameter, you can define what is to
be displayed in standby.
L40
Mask on enabled funct. (Bit 0...7)
L41
Mask on enabled funct. (Bit8...15)
Here, you can specify the functions enabled
via the bus using a binary mask. The bits
have the following meaning:

To determine the value to be parameterised,
all valences must be added together.
L42
Release to delete counters/
Run times
Here the deletion of the running times,
the relay counters and the min/max mem-
ory is enabled for 10 min. Only within the
10 min. the parameters T98, N98 and
A17 can actively delete the correspond-
ing timers, counters or memory locations.
After the 10 min. have elapsed, the release
is removed. The deletion of the min/max
memory by a function assignment of the
keys is not influenced by this.
L99
Password for parameter level
L--
With this parameter, you can set the pass-
word for parameter level
L--
.
