I have an old Hitachi air conditioner without a display. When setting up the remote control, a 26 degree mode is offered, but due to the fact that there is no display, I cannot determine whether the correct mode was set. As a result, the configured air conditioner does not work correctly. When the cooling mode is turned on, the fan mode turns on. How can I fix this?
@Solo79 It sounds like you’re experiencing issues with setting the correct mode on your Hitachi air conditioner through the M3 hub, particularly because the air conditioner lacks a display to confirm the settings. This can indeed be challenging. Based on the reference information, there are some ways you might approach this:
When using the IR Device Management system, it is crucial to ensure that the correct commands are being sent to the air conditioner. Each mode and setting corresponds to a specific command string. For example, cooling mode with a specific temperature and fan setting might be something like M0_T26_S3 for cooling at 26 degrees with high fan speed.
If the mode is not being set correctly, double-check the command strings being sent. You might need to adjust these manually within the app or device management interface to ensure they match the intended settings.
Unfortunately, without a display, confirming these settings directly on the AC can be challenging. You might have to rely on trial and error to ensure the correct combination of mode, temperature, and fan speed is being applied. Also, ensure that the remote control configuration on the M3 hub is correctly aligned with the AC’s actual capabilities.
If this approach doesn’t resolve the issue, I recommend reaching out to the community for shared experiences or contacting the Aqara Customer Service for more tailored troubleshooting. They might have additional insights or updates for your specific situation.
Please feel free to share any further details or updates, and perhaps the community or support team can provide more specific advice!
You can re-pair the M3 with other Hitachi air conditioner remote controls via the Aqara Home App to test if using a different remote might optimize this issue. We suspect the currently paired remote may not be the most suitable one for your air conditioner.
