The HDL M/IRAC.1 KNX Infrared Emitter bridges KNX automation to infrared-controlled equipment — TVs, AV receivers, set-top boxes, and air conditioners. The module stores up to 960 IR codes: 150 for general devices and 810 dedicated to multi-brand HVAC control with temperature, mode, fan speed, and swing functions.

Codes are learned and downloaded via HDL KNX Assistant Software and the HDL-MIR01L.01 IR Code Learner. Optional current detection up to 2 A confirms true on/off state when a single IR code toggles power. Package includes an IR emission tube for flexible positioning near equipment.

Key Features — IR Control with HVAC Library

Code Capacity and Modes

• 960 stored codes: 150 general (TV, DVD, etc.) + 810 AC-specific.
• Control modes: Single emit, repeat emit, sequence emit, air-conditioning control.
• AC functions: On/off, temperature, cooling/heating mode, fan speed, swing.
• IR output: 38 kHz ± 20 % carrier; 7 m emission distance (per datasheet).
• Current detection: Up to 2 A — verify device power state after IR command.

Installation Notes

• KNX bus only: 21–30 V DC — no mains connection to the emitter.
• IR tube placement: Mount emission tube close to target equipment.
• Current clamp: For detection, install near the switched load; follow HDL wiring diagram.

Applications and KNX Integration

• Hotel and living-room AV: Control TV and source equipment from Granite Display scenes via KNX → IR.
• VRF/split AC: Use the 810-code HVAC library for temperature and mode control without a proprietary gateway.
• Code learning workflow: Capture remotes with MIR01L.01 IR Learner, then download to the emitter in ETS/Assistant.
• Additional IR coverage: Add HDL IR emission probes where the bundled tube cannot reach all targets.
• System power: Size the KNX line with an M/P960.1 Power Supply on IR-heavy projects.

Choosing HDL IR Control

The M/IRAC.1 is HDL's KNX high-capacity IR emitter with AC library and optional load-current feedback. For learning codes, use the MIR01L.01 learner. For room-level automation without IR, control loads directly via M/R16.10.1 actuators or M/DM04.1 dimmers.
