RG66000889-REV.00 17
/9: Calibration of evaporator outlet water probe at circuit no.2, B4
It allows to add an offset to the value measured by B4.
/A: Calibration of condensation probe circuit no. 2, B5
It allows to add an offset to the value measured by B5.
/b: Digital filter
It allows to calculate the coefficient relative to the digital filter of the measured value. Give this parameter a high value
(recommended 4) so as to eliminate any noise at analog input lines; they however decrease the sensitiveness of the
probe).
/C: Input limitation
This parameter allows to set the max. variation in the value detected by the probes during any cycle of the unit. The
measure variation range is 0.1÷1.5 units (bar, °C or F according to the probe and the measurement scale) about every
second. Giving this parameter low values allows to limit impulsive noise effects. Recommended value: 8.
/d: Measurement scale
It allows to set the operating mode either in degrees Centigrade or Fahrenheit. As the parameter varies, "µchiller"
automatically turns the values into the new measurement scale.
