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, IQ3 or IQ4 series controllers, the following SET Unique Sensor References should be used:

Thermistor HTST DT (°C) Thermistor HTST DT F (°F) CO2 V (ppm) Alternatively set scaling mode to 5 (characterise) and enter scaling manually as defined in appropriate tables below. Note that for IQ3 and IQ4, the scaling mode and exponent (E) do not need to be set up.

For all other IQ controllers see Sensor Scaling Reference Card (TB100521A).
