AC Control Air for Mitsubishi Heavy Industries

Loxone AC Control Air is a compact interface module for integrating air conditioning units.

For this purpose, a suitable product variant for supported air conditioning systems must be selected.

The different variants vary in the interface used, the connecting cable and the firmware. The AC Control Air takes over the control of the air conditioning in a Loxone installation instead of a conventional remote control.
For this reason, original remote controls of the AC unit (also IR) can no longer be used.

If the AC Unit is turned back on after a power interruption, it will be reinitialized. Depending on the device, this can take a few seconds or up to 15 or 30 minutes. During this time, the AC Unit cannot be controlled with the AC Control Air.

First switch off the air conditioner and then disconnect the mains power supply.

For installation, you need access to electrical connections in the indoor unit of the air conditioner. Refer to the installation or service manual for the air conditioner you are using to determine how to remove the covers and where the various terminals and connectors are located.

Locate the screw terminals X/Y for the wired remote control in the Mitsubishi indoor unit. If a remote control is connected, it must be disconnected and can no longer be used.

Connect the AC Control Air to the terminals with the enclosed connecting cable as follows:

Some air conditioners are not equipped with X/Y terminals. In this case, the additional adapter board SC-BIKN-E(A) from Mitsubishi Heavy Industries is required, which provides the X/Y terminals.

Fasten the AC Control Air to a suitable place in the device, e.g. with a cable tie.
Make sure that the device cannot come into contact with mains voltage, hot, cold or moving components, or moisture.

For best reception, the AC Control Air has to be placed outside of metal covers. The supplied connecting cable must not be extended.

Finally, reinstall the housing covers and turn on the mains supply and the air conditioner.
The AC Control Air is now supplied with voltage from the air conditioner and can be paired in the next step.

Remember to remove or disable any existing AC unit remote controls as they can no longer be used.


In delivery state, pairing mode will be active after the power supply has been established. This is indicated by the status LED flashing red/green/orange.

Then follow the pairing procedure on the Air Interface.

To activate the pairing mode manually, switch off the power for 10 seconds, then switch it back on. If no connection to a Miniserver can be established for two minutes, then pairing mode is activated for 5 minutes.


Loxone AC Control Air is programmed and set up using the AC Control function block in Loxone Config:


In case the communication with an air conditioner does not work (correctly), a diagnostic analysis can be started in the context menu of an AC Control Air. This enables communication data to be displayed and recorded:
