41ABB i-bus ® EIB / KNX Planning and application4.2 Planning example:“Humidity sensor”The air conditioning and heating in a laboratory is to be controlled inrelation to the relative humidity. If the value falls below 20%, the airconditioning should be switched off and the heating should be switched on.If the value rises above 75%, the air conditioning should be switched on andthe heating should be switched off. The minimum duration of the underflowor overrange is a maximum of 30 seconds.The relative humidity should not be evaluated below 10% and over 90%.Humidity sensor:Signal output: 0 – 1000 ohmMeasuring range: 0...100%Measurement curve: LinearThreshold 1: Air conditioningThreshold 2: HeatingConnection to channel A.
