Wireless temperature humidity sensor, anthracite matt, 75x25x12mm, with battery (service life 5 years) and solar cell. Smart home sensor The radio temperature/humidity sensor measures the relative air humidity between 0 and 100% (+-5%) and the temperature between -20degrees C and +60degrees C (+-0.5degrees C). It transmits a data telegram to the Eltako building radio within 2 minutes if the change occurs. If no change is made, a status message frame is sent every 10 minutes. Secured by glue; an adhesive film is included. The electronics are powered by an internal button cell CR2032. To change the battery, you simply have to open the casing. This is also necessary to activate the battery supply by pulling out an insulating strip. The factory setting for the EEP is A5-04-02 active, the internal jumper only connected to one pin. This jumper can be used to switch to the EEP: A5-04-03, to do this, the casing must be opened and the jumper connected to both pins. To learn in an actuator, the housing must be opened and the internal button pressed.This text is machine translated.
