The Eelectron MO04L02KNX-3 is the LITE version of the OL-U KNX multisensor in black: the same temperature, humidity and CO2 sensing, dual 2-stage PI thermostats and backlit LCD as the MO04A01KNX, delivered as a pre-assembled unit with four white-LED buttons and a non-capacitive RGB status bar at a lower price point. It is the volume choice for hotel guest rooms, student housing and multi-family projects where every room needs climate, air-quality and lighting control from one wall device.
The two thermostats control heating, cooling, valves, 6-way valves and 2-/4-pipe fan coils for two zones; the humidity channel manages humidification and dehumidification with hysteresis; CO2 (400–2000 ppm) supports demand-controlled ventilation. Four mechanical buttons handle on/off, dimming, shutters and scenes, 32 logic blocks and the Virtual Holder hospitality logic are built in, and the device supports KNX Data Secure. The LITE mounts in a 2- or 3-module box with the raw-plastic FO71A01 frame. The white version is MO04L02KNX-1.
