of the hysteresis’ value is effective below and half of the value above the switching point. The one-
sided hysteresis works downward with heating contact and upward with cooling contact.
A60: Sensor type
These parameters permit selection of the sensor type, if the needed hardware prerequisites are
available.
A70: Software filter
With several measuring values, it is possible to obtain an average value. This parameter can
determine by how many measured values an average value is to be formed. If a sensor with a very
fast reaction to external influences is used, an average value ensures a calm signal process.
A80: Temperature scale
Indication can be switched between Fahrenheit and Celsius. At conversion, the parameters and
setpoints maintain their numerical value and adjustment range. (Example: A controller with the
desired value of 0°C is switched to Fahrenheit. The new desired value is then interpreted as 0°F,
which corresponds to a temperature of -18°C).
NOTE: Indication limits with °F can be smaller than the actual measuring range!
U1: Function output K1
U2: Function output K2
U3: Function output K3
U4: Function output K4
Generally, the outputs are exchangeable with parameter adjustments, in order to achieve an
optimal relation of the existing hardware with regard to contact rating, kind of contact and cycle
number. Therefore, these parameters first assign the outputs to the controller function.
b0: Function E1
With this parameter function of the ext. input E1 can be set. With b0=0 the E1 is not evaluated.
With. With b0=1 setpoint S1 is switched to setpoint S1’ when input E1 is closed. With b0=2 the
controller is switched to the standby mode.
b1: Function key 1
This parameter activates a special function for function key 1. This can be the either the standby
function or the activation of the display according to parameter A34. If the standby function is set
parameter b3 selects an English or German text.
b3: Text if in standby mode
With this parameter one can select the text to be displayed if the controller is in standby mode. A
German or an English text can be selected.
L0: Individual address (Node)
L1: Individual address (Subnet)
STOERK TRONIC devices can be hooked with "self installation". In this case, however, each
participant has to be assigned a clear address. This address corresponds to the knot address and
subnet address with Domain=0.
The address of the knot can only be changed, if the knot was not tied externally (SNVT
"nciNetConfig" = CFG_LOCAL), otherwise the changed value is not saved (after releasing the set
key the old value is reset).
Lr: Reset parameters
This parameter is special as it can reset all parameters to the condition ex works. At setting Lr = 1
reset takes place, and Lr itself is reset to zero again. Note that customised values will become
effective if these were adjusted prior to delivery.
