The Interra iXM Thermostat is the LCD / IPS touch branch of the ITR333 KNX Secure family (Interra title: iX-M 3″ Touch Panel). Coding uses X1=1 (LCD, no AQI), aluminium X3=1, and button digit X2=4 → ITR333-141x or X2=8 → ITR333-181x, plus finish X4. The IPS screen adds thermostat pages, AC control, up to 96 functions across 16 pages, meters/sensors/weather views, timers, alarms, passwords and themes — beyond the mechanical buttons alone.

Bus current rises to about 80 mA for LCD models (ITR333-1XXX). Integrated sensors: temperature (±0.2 °C), humidity (±2 %RH), ambient light (to 1800 lux) and proximity; HVAC modes comfort / standby / economy / protection with 2-point, PWM or continuous PI. Up to 13 languages. Same ETS database as the no-LCD iXM Switch. Typical LCD outline 86 × 141 × 11.7 mm.
