Parameter description:
P0: Actual value
The here indicated temperature presents the actual measured value. If the control setpoint is
indicated by the help of parameter A32, the actual value can only be seen with this parameter.
P1: Setpoint / DeltaW for control circuit 2
Adjusting the setpoint of control circuit 2.
If A5=1, the setpoints for control circuit 1 and 2 are linked with one another via switching difference
DeltaW, which can be adjusted with P1. (operation with DeltaW)
The following applies: setpoint thermostat 2 = setpoint control circuit 1 + delta W2.
This difference can take positive or negative values. Thus, a leading or following contact can be
realised.
P2: Hysteresis contact K1
P3: Hysteresis contact K2
The hysteresis can be set symmetrically or one-sided at the setpoint (see A40, A41).
At one-sided setting, the hysteresis works downward with heating contact and upward with cooling
contact. At symmetrical hysteresis, half of the hysteresis’ value is effective below and half of the
value above the switching point (see fig. 1 and 2).
Fig. 1: Heating controller, one-sided hysteresis Fig. 2: Cooling controller, symmetrical
hysteresis
P4: Control range limitation – minimum setpoint
P5: Control range limitation – maximum setpoint
The adjustment range of the setpoint can be limited in both directions. This is to prevent the end
user of a unit from setting inadmissible or dangerous setpoints.
P6: Actual value correction
This parameter allows the correction of actual value deviations caused for example by sensor
tolerances or extremely long sensor lines. The regulation measure value is increased or decreased
by the here adjusted value.
P19: Key-lock
The key-lock allows blocking of the control keys. In locked condition parameter adjustments with
keys is not possible. At the attempt to adjust the parameters despite key-lock the message "==="
appears in the display.

P30: Lower alarm value
P31: Upper alarm value
The exit alarm is a boundary alarm or a range alarm with one-sided hysteresis (see parameter
P32). Both at the boundary alarm and the range alarm, limit values can be relative, i.e. going along
with the setpoint S1/S1’, or absolute, i.e. independent of the setpoint S1/S1’. At boundary alarm the
hysteresis works one-sided inwardly, and at range alarm outwardly (see fig. 3-6).
P32: Hysteresis alarm circuit
Hysteresis is set one-sided at the adjusted limit value. It becomes effective depending on alarm
definition (see fig. 3-6).

Third control level, (A parameters):
Setting of control parameters
Access to the third control level is granted when selecting the last P-parameter on the second
control level. Continue to press the UP key for approximately 10 seconds until “PA” appears.
Continue to press the UP key and additionally press the DOWN key for about 4 seconds and the
first A-parameter of the third control level is indicated.
With the keys UP and DOWN you can scroll the list in both directions. Pressing the SET key will
give you the value of the respective parameter. By pressing the UP or DOWN key at the same time
the value can be adjusted.
Return to the initial position takes place automatically, if no key is pressed for 60 seconds, or by
simultaneously pressing the UP and DOWN key for approx. 4 seconds.

Parameter description:
The following values can change the equipment characteristics
and are therefore to be set with utmost care.
A1: Switch mode contact K1
A2: Switch mode contact K2
The switch mode for the relays, i.e. cooling or heating function, can be programmed independently
at works. Heating function means that the contact opens as soon as the setpoint is reached, thus
power interruption. At cooling function the contact closes, if the actual value is above the required
setpoint. (see fig. 1 + 2)
A3: Function of contact K1 at sensor error
A4: Function of contact K2 at sensor error
At sensor error the selected relay falls back into the condition pre-set here. If there is a data-loss in
parameter memory (display indicates “EP”) both contacts K1 and K2 are switched off.
A5: Selection setpoint 2 or DeltaW
This parameter determines whether the setpoints for thermostat 1 and 2 independently adjustable
(A5=0) or whether they are tied with one another via a switching offset DeltaW (A5=1). This
parameter applies only to contact K2 (see parameter P1).
A8: Display mode
The value can be indicated in integrals or with decimals in 0,5°K or 0,1°K. At indication in 0,5°K the
value is rounded up or down. In general, all parameter indications are presented in 0,1°K.
A9: Weighing factor
With this parameter the actual value can be submitted to weighing. The measured value is
multiplied by it and both indicated in the display and applied for regulation.
A10: Indication value for lower value linear analogue input
A11: Indication value for upper value linear analogue input
Only relevant, if the controller is programmed for a voltage input (0…10V linear) or a current input
(4…20mA linear). These parameters allow scaling of the linear analogue input. The value to be
indicated for the lower and upper entrance value then defines the range the controller will indicate.
For input range 4…20mA the display will show sensor error if the input signal drops below 4mA.
A19: Parameter lock
This parameter enables locking of each parameter level. If third level is locked, only parameter A19
may be changed.
A20: Activation of key acknowledgement
This parameter permits to switch on/off the key confirmation by internal buzzer.
A30: Function alarm exit
The alarm exit evaluates an upper and a lower limit value (see parameters P30 and P31), whereas
a selection is possible as to whether the alarm is active if the temperature lies within these two
limits, or whether the alarm is released if the temperature lies beyond them. In the case of sensor
error, the alarm is activated independently of this adjustment. The exit can also be inverted, so that
it functions like a release (see fig. 3 – 6 at parameters P30/31).
A31: Special function at boundary or range alarm
Here can be selected whether, in the case of an alarm, the indication to flash and/or the buzzer is
to start. Sensor alarm (display F1L or F1H) is indicated independently thereof by flashing display
and the buzzer.

A32: Setpoint display
A32=0 indicates the actual value, A32=1 statically indicates the setpoint S1 or S1’ in the display.
Therefore, the current actual value can only be indicated with parameter P0.
A33: Adjustment of setpoint S1‘ (not available on all types of controllers)
By closing switching input E1, setpoint S1 can be switched to a setpoint S1’. Setpoint S1’ can be
either relative to setpoint S1 or an independent, freely adjustable, control setting.
The setpoint S1’ can only be accessed if input E1 is closed. The setpoint S1’ can only be activated,
if the external input is configured for setpoint change-over (parameter A81=2 or 3).
A40: Hysteresis mode contact K1
A41: Hysteresis mode contact K2
These parameters allow selection as to whether the hysteresis values which are adjustable with
P32, are set symmetrically or one-sided at the respective switching point. At symmetrical
hysteresis, half 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 (see fig. 1 + 2).
A50: Minimum action time contact K1 ”On”
A51: Minimum action time contact K1 ”Off”
A52: Minimum action time contact K2 ”On”
A53: Minimum action time contact K2 ”Off”
These parameters permit a delay in switching on/off the relay in order to reduce the switching
frequency. The adjusted time sets the entire minimum time period for a switching-on or switching-
off phase.
A54: Delay after “Power-on”
This parameter allows a switching-on delay of relays after switching-on the mains voltage. This
delay corresponds with the time set here.
A55: Mutual delay of contacts K1 and K2
This parameter makes a mutual switching-on delay of relays possible, depending on whichever
contact is switched first.
A56: Alarm suppression after "Power-On"
This parameter allows a switching-on delay of the alarm contact after switching on the mains
voltage or setpoint change-over. This delay corresponds with the time set here.
A60: Sensor type
These parameter permits 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!

A81: Function E1
With this parameter function of the ext. input E1 can be set. With A81=0 the E1 is not evaluated.
With A81=1 the controller is switched to the standby mode. With A81=2 or A81=3 setpoint S1 is
switched to setpoint S1’ when input E1 is closed. With A81=3 the status of E1 is indicated by LED3
in the display.
A82: Function „key 5“ (Standby)
A83: Function „key 3“
The following functions are available:
0: the respective key has no function
1: the controller is switched to standby mode
2: the key is linked with the function of parameter P1
3: a relay (indicated with parameter A90-92) can be switched on or off directly with the key.
In standby mode the key is locked and the corresponding relay switched off. After
restarting the corresponding relay remains switched off
4: like 3, but the relay is switched despite of the standby mode.
A90: Output connection relay K1
A91: Output connection relay K2
A92: Output connection relay K3
Depending on existing hardware there may not be all output relays. This parameter assigns the
respective relay to the internal controller outputs, to key 3 or 5, to the alarm contact or the buzzer.
