The top terminal pins are multiplexed functions, and the specific function definitions are determined
according to the model selection table.
Tips:
Resistance Thermal Detector (RTD) compatibles 2-wire or 3-wire, please reference above mentioned wiring instruction. If
the sensor near the module and the wire resistance is small can be ignored, can be used 2-wire wiring, if the distance is far
and the wire resistance affect the value, should be used 3-wire way connection.
