Parameter description:
The following values can change the equipment characteristics
and are therefore to be set with utmost care.
P0: Indication actual value of sensor F1
The here indicated temperature presents the sum of actual measured value of feeler F1 and the
actual value correction according to parameter P1.
P1: Calibration sensor F1, 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.
P2: Indication actual value of sensor F2
The here indicated temperature presents the sum of actual measured value of sensor F2 and the
actual value correction according parameter P3.
P3: Calibration sensor F2, 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.
P4: Evaluation of sensor F2
Sensor F2 can be used for the determination of the evaporator temperature (P4=1) or for the
second thermostat (P4=2).
If, in simpler refrigerant plants only the refrigerating chamber sensor is used, the feeler entrance for
sensor F2 as well as its data recording (P4=0) can be deactivated here. Among other, parameter
d2 has no meaning in the deactivated condition.
P5: Indication mode
The actual value can be indicated with different accuracy.
Actual values and parameter values are always set for highest accuracy.
P6: Display unit, indication in standby mode
This parameter allows display settings (°F or °C) and ("AUS" or "OFF") in standby mode.
P7: Sensor type
This parameter makes it is possible to adjust the feeler type of both sensors. Depending on the
hardware not all sensor settings are possible.
P8: Filter
This parameter can determine by how many measured values an average value is to be formed.
P9: Weighing factor for measuring value of refrigerating chamber sensor F1 (data record 1)
P10: Weighing factor for measuring value of refrigerating chamber sensor F1 (data record 2)
The actual value of the respective data record can be submitted to weighing. In this case the actual
value is formed by a mixing ratio of the measuring values of sensor F1 and F2. (new function of the
sensors as supply-air and exhaust-air sensor).
At standard setting [P9 = 100%] the actual value corresponds to the refrigerating chamber sensor.
As soon as parameter P9 differs from 100% the measuring values are submitted to weighing.
The actual value then is formed as followed:
Actual value = (P9 * measuring value F1 + (100 – P9) * measuring value F2) / 100%
F1 = refrigerating chamber sensor / supply air
F2 = evaporator sensor / exhaust air
