Temperature0 to 10 V for 0 to +40 °C (32 to 104 °F)

CO2 concentration0 to 10 V for 0 to 2000 ppm

Humidity (/H/ option only)0 to 10 V for 0 to 100 %RHMeasurement range 0 to 95 %RH

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: CO2 V (ppm) Humidity V (%RH) - /H/ option only Temp V 0+40 (°C) Temp V +32+104 F (°F)Alternatively set scaling mode to 5 (characterise), and enter scaling manually as defined in the appropriate tables below. Note that for IQ3, scaling mode and exponent do not need to be set up.For all other IQ controllers see Sensor Scaling Reference Card TB100521A.
