1 V1.0.0 ( ) 1 (10) OUNTING The device can be installed in dry surroundings (I20) by screws on the wall surface or on the standard flush mounting box. The recommended installation height is cm. The device position should be selected carefully. All the error factors that can affect to the measurements should be eliminated as well as possible. The following list defines the typical measurement error factors. direct sun light occupant proximity air flow coming from windows or doors air flow coming from ventilation nozzles air flow coming from the flush mounting box differential temperature caused by external wall Wiring Device wiring and commissioning can only be carried out by qualified professionals. Always make the wirings while the power is switched off. SELECTING THE EASUREENT INFORATION TO BE VIEWED ON THE DISLAY The measurement values scroll on the N model display. The wanted value can be locked to view continuously by pressing the S1 button. You resume to the scrolling view by pressing the S1 button again. A. S1 button NOTE: In models, the shown measurement information can be selected also via odbus.
