Parameter Definitions
/2 Measurement stability.
Defines the coefficient used to stabilise the temperature reading.
/3 Probe display rate
Sets the rate at which the temperature display is updated.
/4 Probe average (Virtual probe)
Used to choose whether to control the temperature based solely on the room probe reading, or
alternatively whether to refer to the average of the room probe S1 and probe 2(S2, see parameter /A2).
/5 Select °C or °F
Defines the unit of measure in degrees centigrade or Fahrenheit.
/6 Decimal point
Used to enable or disable the displaying of the temperature with the resolution to the tenth of a degree
between –20 and +20.
/tI Probe displayed by instrument
Select the probe to be displayed by the instrument.
Warning: Control is always based on the virtual control probe.
/tE Probe displayed on external terminal
Selects the probe to be displayed on the remote terminal.
/P Select type of probe
Used to select the type of probe for temperature measurement.
Default. /P = standard NTC probe with range –50 to +90°C.
/A2 Configuration of probe 2
Used to configure the operating mode of probe 2.
Default: /A2 =2 = Defrost probe.
/A3 Configuration of probe 3
Used to configure the operating mode of probe 3.
Default: /A3 = 0 = Probe 3 absent.
/A4 Configuration of probe 43
Used to configure the operating mode of probe 43.
Default: /A4 = 0 = Probe 4 absent.
/C1 Calibration or offset probe 1
/C2 Calibration or offset probe 2
/C3 Calibration or offset probe 3
/C4 Calibration or offset probe 4
These parameters are used to correct the temperature by the probes using an offset.
Example: To decrease the temperature measured by probe 1 by 2.3 degrees, set /C1 = -2.3.
St Set point
Establishes the controller set point.
Default: St = 0.0
rd Control delta
Establishes the value of the differential, or hysteresis, used to control the temperature.
Default: rd = 2.0. Foster setting: rd = 4.0
r1 Minimum allowed set point
Determine the set point minimum value.
Default: r1 = -50. Foster setting: r1 = -26.
r2 Maximum allowed set point.
Determine the set point maximum value.
Default: r2 = +60. Foster setting: r2= -15.
