Set up IQ Sensor Type

It is recommended to use SET (Software Tool) for the setting of the sensor type module.
For all IQ2 series controllers with firmware version 2.1 or greater, or IQ3 series controllers,
the following SET Unique Sensor References should be used:

PRT I -10+40 (T/PI/40, °C)
PRT I +14+104 F (T/PI/40, °F)
PRT I -10+110 (T/PI/110, °C)
PRT I +14+230 F (T/PI/110, °F)
PRT I -40+50 (T/PI/-40, °C)
PRT I -40+122 F (T/PI/-40, °F)

Alternatively set scaling mode to 5 (characterise) and enter scaling manually as defined in
the appropriate table below. Note that for IQ3, the scaling mode and exponent do not need
to be set up.

For all other IQ controllers see Sensor Scaling Reference Card TB100521A
