===== Operation principle =====

As HIQ temperature regulation support fan-coils with 3 speed fan control, same principle is used for AC control. Instead of control valve and fan speed, system send IR commands as per following diagram.

{{hiq_building_automation:hiq_home:extensions:ir_blaster:ir_blaster_diagram.png?nolink|}}


Depending on AC possibilities and user preferences different IR commands for HEAT 1-3 and COOL 1-3 can be used. In the following table there is an example for IR commands for Panasonic inverter AC.

**1. Load IR commands from file**

Download IR commands definition file: {{ hiq_building_automation:hiq_home:extensions:ir_blaster:ac_panasonic_inverter.zip |}}

Definition file is for Panasonic inverter AC and following commands:

^  command       ^   AC remote setting                    ||||
^  :::           ^  mode  ^  setpoint  ^  fan  ^  air swing  |
^ cmd1 - OFF       |  OFF   |            |       |             |
^ cmd2 - HEAT 1    |  HEAT  |   25°C     |  1/5  |  AUTO       |
^ cmd3 - HEAT 2    |  HEAT  |   25°C     |  2/5  |  AUTO       |
^ cmd4 - HEAT 3    |  HEAT  |   25°C     |  5/5  |  AUTO       |
^ cmd5 - COOL 1    |  COOL  |   18°C     |  1/5  |  AUTO       |
^ cmd6 - COOL 2    |  COOL  |   18°C     |  2/5  |  AUTO       |
^ cmd7 - COOL 3    |  COOL  |   18°C     |  5/5  |  AUTO       |

Load IR from downloaded file.

If commands are not compatible with used AC or user needs are different from commands in file proceed to step 2, otherwise go to step 3.

**2. Learn new IR commands**

  - Clear all commands.
  - Select which command to learn.
  - Press "Learn On" button. Prepare AC remote, aim IR remote transmitter to IR Input on AC blaster and press AC remote button which will send IR command to be learned.
  - Test learned command. If command is not working repeat from step 3.
  - Save IR command when it is working as expected.

Repeat steps 2-5 for all commands.
