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 Reference should be used:
Thermistor: Thermistor TBTO (°C)
Thermistor TBTO F (°F)
Alternatively set scaling mode to 5 (characterise), and enter scaling manually as defined in the
appropriate table below.
For all other IQ controllers see Sensor Scaling Reference Card TB100521A.
