The Eelectron MO04A01KNX-3 is the OL-U KNX multisensor in black, a wall-mounted room controller for 2- or 3-module flush boxes that combines temperature, humidity and CO2 sensing, two independent 2-stage thermostats, four mechanical pushbuttons and a backlit LCD in one 71 × 71 mm device. It is designed for the guest room, executive office or apartment living area where the client wants one elegant wall point for climate, air quality and lighting rather than a thermostat plus keypad plus sensor.
The two thermostats each run a PI controller for heating, cooling, valves, 6-way valves and 2-/4-pipe fan coils, so a bedroom and bathroom (or office and meeting area) can be controlled from one device; the humidity channel manages humidifiers and dehumidifiers with hysteresis thresholds; and the CO2 reading (400–2000 ppm) drives demand-controlled ventilation. A capacitive swipe bar under the display handles scenes and slow-swipe dimming or set-point changes, an RGB LED bar and one RGB LED per button show status, and 32 logic blocks plus the Virtual Holder hospitality logic are built into the Data Secure ETS application. Button kits and frames in plastic, metal or FENIX are ordered separately; the black finish takes the BKM4PLL-3 key set. Other finishes: MO04A01KNX-1 (white), MO04A01KNX-4 (Helvetia white).
