3. Operation

PV/SV display indicates the characters of the sensor type and temperature unit for approx. 2 seconds after the power is turned on. During this time, all outputs and the LED indicators are in their off status. (Refer to table 3.1-1 and 3.1-2.) After that, actual temperature or the main setting value is indicated, and control starts. (If PV display is selected in PV/SV display selection, the actual temperature will be indicated. If SV display is selected, the main setting value will be indicated.)
