The Interra ITR415-0001 is a mid-range KNX presence multi-sensor for flush-mounted indoor ceilings. It combines presence, movement, and brightness detection with internal room-temperature measurement and thermostat control in a compact housing — Interra positions it as the thinnest design in its class for hotel, office, and classroom automation.

Detection range is 11 m to 14 m (mid-range). Four independently configurable presence channels support constant-light and multi-zone logic; four logic blocks (AND, OR, XOR), master/slave mode, and a virtual card-holder function suit hospitality energy management. Three configurable inputs accept 2 digital + 1 analog or 3 digital wiring. Configuration is via ETS.

Key Features — Presence, Light, and HVAC

• Detection: Presence, brightness, movement; internal and external temperature.
• Range: Mid-range 11–14 m (manufacturer specification).
• HVAC: Room temperature measurement and thermostat objects on the KNX bus.
• Logic: 4 presence channels; 4 logic gates; virtual card holder for hotel rooms.
• Inputs: 3 configurable inputs (2 DI + 1 AI or 3 DI).

Applications and KNX Integration

• Offices and classrooms: Occupancy-based lighting and HVAC with brightness-led constant light control.
• Hotel rooms: Virtual card-holder logic with ITR504 combo actuators for switched loads.
• Room interfaces: Pair with iSwitch+ Aluminium or iX3 / iX4 touch panels for guest control.
• Bus power: Size lines with ITR900 640 mA PSU on extended installations.

Choosing Interra Presence Sensors

ITR415-0001 is the 14 m mid-range model with thermostat. For higher density switching after occupancy logic, add ITR508 or ITR512 combo actuators on the same line.

Manufacturer order codes (FM)

This sensor is available in 2 order codes (white and black housings). Both are flush-mounted (FM) KNX presence multi-sensors with integrated thermostat and 11–14 m detection range.
