F66
Condenser fan: P-controller proportional range
For setting the proportional range required for
[F65 = 4
] in which the fan is to be placed.
F67
Condenser fan: Minimum speed
The lowest value of voltage at which a connected fan still runs is set.
F68
Condenser fan: Start boost
This specifies the time with which a stationary fan is switched on with max. voltage so it can start up in a stable manner.

Actual value of sensors F1..F4
The temperature value displayed here is used for control purposes. It is calculated from: Actual control value = (actual
measured value * weight factor ) + actual value correction. The actual value correction and weighting factor must be specified
in the following parameters. In special applications (refrigerated display cabinets or similar), this corrects any actual value
deviation caused by unfavourable positioning of the sensor.
H51
Weighted average of sensors F1 and F2
This calculated average value of sensors F1 and F2 can be useful for the control loop or the display. It is calculated as
follows:
H51
= (
H53

H11
+ (100

Sensor calibration F1...F4 actual value correction
This parameter can be used to correct actual value deviations caused, for example, by sensor tolerances, extremely long
sensor cables or by structural protective circuits (e.g. Ex barriers). The value set here is added to the measured value.

Weighting factor F1…F4
This parameter can be used to correct actual value deviations due to unfavourable positioning of the sensor. The controller
measured value is multiplied by the value set here.

Sensor selection F1…F4
This parameter is used to set the sensor type. Depending on the hardware, not all sensor types can be supported. For the
NTC sensor, a parallel resistor must also be connected.

Software filter F1…F4
This parameter is used to determine the number of measured values from which an average value is calculated. An average
value is formed from the last measured values, whereby the oldest measured value is deleted (so-called "moving average
filter").

= 7 or 8 (0...20 mA or 4...20 mA linear sensor) is selected for the sensor selection, this parameter can
be used to determine which value is to be displayed at a current of 0 or 4 mA. The display value for 20 mA is specified in
the next parameter. The actual measured value is calculated as linear interpolation between these two values.
