2. ce value determines the smallest selectable reference value HS The upper limit of the reference value determines the largest selectable reference value CA The measured temperature can be calibrated by the actual temperature offset P7 The activation break determines the minimum resting time between two switching operations while the relay contact will be closed This break is also valid if the device is switched off or the supply voltage is interrupted AH The exceeded temperature alarm determines from which current value above the reference value the display starts to blink The selection of 0 disables the alarm AL The deceeded temperature alarm determines from which current value below the reference value the display starts to blink The selection of 0 disables the alarm Error messages EEE Sensor not connected lead fracture LLL Measured temperature below 50 C HHH Measured temperature above 110 C Hints The QC PC CC 12 is a so called two position controller If necessary the heating or cooling is hereby activated or deactivated Thereby a temperature control can be realized inexpensively This kind of control is always utilized when an inert feedback control system should be handled such as in refrigerators or for the tempering of well insulated masses In such situations a change of the temperature happens rather slow with the result that after the deactivation the tempering energy has to be reactivated not befor
