It is recommended to use SET (software tool) for the setting of sensor type modules. 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: Humidity I

Temperature: Thermistor HTST DT (°C)

Thermistor HTST DT F (°F)

(change the values of U and L to +50 and -5 °C or +122 and +23 °F

respectively)

If not using SET, use the following tables for all IQ2 series controllers of firmware version 2.1 or greater

or IQ3 controllers; for all other IQ controllers see Sensor Scaling Reference Card TB100521A.

2.1 Maintenance

Over time, the sensing element may get covered in dust. The dust can be removed using compressed

air. Under no circumstances should water or cleansing agents be used on the sensing elements.

It is recommended that the accuracy of the sensor is verified every 12 months. If the sensor falls outside

the quoted accuracy, or the sensor tip is damaged, replace the tip as shown below.

Open housing

Unscrew board

Remove old sensor tip

Caution: This unit contains static sensitive

devices. Suitable ant-static

precautions should be taken

throughout the operation to

prevent damage to the units.
