The Eelectron TO04A01KNX is the regular OL-U KNX thermostat hardware: a wall-mounted room controller for 2- or 3-module flush boxes with an integrated temperature sensor, two independent 2-stage PI thermostats, a backlit LCD, four mechanical pushbuttons configured as 8 channels with an RGB LED each, and a capacitive swipe bar with an RGB LED bar. It is the design-grade room controller of the OL-U range for hotel guest rooms, residences and executive offices, finished with button kits and frames in painted plastic, metal or FENIX that are ordered separately.

Each thermostat drives heating, cooling, valves, 6-way valves and 2-/4-pipe fan coils, so two zones (bedroom and bathroom, office and meeting area) are handled from one device. The swipe bar takes quick swipes for scenes (Welcome, IN…) and slow swipes for dimming, set-point or colour, plus tap, double-tap and long-press; the 8 button channels cover on/off, dimming, shutters and blinds, scenes and sequences. Thirty-two logic blocks and the Virtual Holder hospitality logic are built into the KNX Data Secure ETS application. The version with humidity sensor is HO04A01KNX; the LITE version without swipe bar is TO04L02KNX-1 / -3; for CO2 and humidity choose the MO04A01KNX multisensor.
