The Interra iX3 KNX Panel is a 4-inch IPS secure touch room controller (ITR331-0001 black, ITR331-0002 white). It centralises lighting, climate, shading, and air-quality feedback in a low-power display with wide viewing angles and adjustable backlight.

Integrated temperature, humidity, brightness, and air-quality sensors feed thermostat and automation logic. HVAC support includes 2-point, continuous, and PWM thermostat modes plus control of air-conditioning units through KNX AC gateways. The UI supports 13 languages; all iX3 variants program from the same ETS database. Configuration is via ETS (KNX Secure on secure variants).

Key Features — 4″ IPS Room Controller

• 4″ IPS touch display — high contrast, low consumption, friendly UI.
• Environmental sensing: Temperature, humidity, brightness; AQI on selected SKUs.
• Climate: Heating/cooling modes; AC gateway integration.
• Automation: Lighting, scenes, shutter/blind, and feedback from bus sensors.
• Commissioning: Single ETS product file for the iX3 family.

Applications and KNX Integration

• Residential and hotel rooms: Primary wall controller for HVAC and lighting.
• Customisable UI: For layout-rich control, compare iX4 (480×480, up to 128 functions).
• Compact secure rooms: iX2 Secure 2″ where space is limited.
• Sensors and loads: ITR415 presence sensor and ITR504 combo actuators on the same line.

Choosing Interra Touch Panels

iX3 balances a proven 4″ IPS UI with built-in environmental sensors. Specify iX4 when projects need configurable page layouts (1×2, 1×4, 2×4) and optional proximity sensing on one device.
