Set up IQ Sensor types
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:
Humidity HT/D, HT/D/2% :Humidity I
Temperature HT/D/2% :PRT I 0+40 (°C)
PRT I +32+104 F (°F)
Temperature HT/D :Thermistor HTST DT (°C)
Thermistor HTST DT F (°F)
Alternatively set scaling mode to 5 (characterise) and enter scaling manually as defined in appropriate tables below. Note
that for IQ3 the scaling mode and exponent (E) do not need to be set up.
For all other IQ controllers see Sensor Scaling Reference Card TB100521A
