The Interra ITR415-0003 is the wide-range white model in the ITR415-0XXX KNX multi-presence family (coding: colour white, no thermostat, wide-range optics). It combines PIR presence / movement, 1–1200 lux brightness, internal temperature and optional external NTC temperature into one ceiling device for indoor lighting and HVAC automation. Four independent presence channels support constant-light switch or constant-light control; four logic blocks (AND / OR / XOR) and master/slave mode cover larger rooms and open-plan zones.

At 3 m mounting height the wide-range pattern reaches about 7 m seated, 14 m walking towards and 24 m walking across (Interra detection table). Bus current is typically 5 mA. Three rear inputs (2× digital + 1× digital/analogue) accept push-buttons or an external NTC (e.g. HM001718). A virtual card-holder mode suits hotel door-contact presence. Flush mount is IP20; optional surface casing raises protection to IP44. For a tighter mid-range footprint see ITR415-0001.

Key Features — Wide-Range Multi Sensor

• Wide-range PIR: Larger walking-across coverage than mid-range siblings.
• 4 presence channels: Constant light switch / controller; auto or semi-auto.
• Brightness + temperature: 1–1200 lux; internal and external temp objects.
• Logic & hotel tools: 4× AND/OR/XOR blocks; virtual card holder.
• 3 inputs: Buttons for switch, dim, shutter, scene, RGB, HVAC mode.
• Compact ceiling: Ø 70 × 41.8 mm; KNX certified; ETS only.

Choosing and Commissioning

Confirm coding 0003 (white, no thermostat, wide-range). Mount indoors away from HVAC outlets, reflective surfaces and swaying objects. Connect KNX (21–30 V DC bus) and optional input wiring, then program with the family .knxprod. Calibrate brightness with a luxmeter via ETS when using constant-light control.
