•

before connecting the power, check the correct value of the power supply as shown on the label of the instrument;

•

all models use NTC probes, except for the PJ32S6E0*, which uses PTC probes;

•

for models S200 and S201 the alarm relay can be set as normally energised or normally de-energised, using parameter

+.
