Parameter description:

P2: Hysteresis contact K1

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 symmetrical 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, or absolute, i.e. independent of the setpoint (see fig. 3 and 4 next page). At
boundary alarm the hysteresis works one-sided inwardly, and at range alarm outwardly.

Boundary alarm function (see fig. 3): Range alarm function (see fig. 4):
The alarm contact is closed if the process Opposite switching behaviour to the boundary
temperature is above the upper or below the value alarm. The alarm contact is closed if
lower boundary value. the actual value remains between the
boundary values.

Fig. 3: Boundary alarm, rel. boundaries Fig. 4: Range alarm, abs. boundaries

P32: Hysteresis alarm circuit

Hysteresis is set one-sided at the adjusted limit value. It becomes effective depending on alarm
definition.

d0: Defrosting interval

The "defrosting interval" defines the time, after which a defrosting process is started. After each
defrosting start, this time is reset and runs the next interval.

d2: Defrosting temperature limit

This permits to terminate defrosting when the adjusted desired temperature value is reached. The
defrosting time set with "d3" nevertheless runs at the same time, i.e. it functions as safety net to
terminate the defrosting process in case the defrosting temperature is not reached.

d3: Defrosting time limit

After the here set time the defrosting process is terminated.
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

The switch mode for the relay, 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

At sensor error the 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.

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.

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.

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 (see fig. 3 – 4 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).
A40: Hysteresis mode contact K1
These parameters allow selection as to whether the hysteresis value which is adjustable with P32,
is 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”
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.

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 setpoint S1 is switched to
setpoint S1’ when input E1 is closed.

A82: Function standby key

The following functions are available:
0: the respective key has no function
1: the controller is switched to standby mode
