@vinz86 Contact Mitsubishi and an engineer attends and updates it for you for free. we had this done for a couple of our customers, our customers contacted Mitsi and explained about this high pitch noise and 1 week later the engineer attended and updated the machine.

Mitsubishi ecodan PUZ-WM112VAA outdoor unit firmware update

Vinz86 — Wed, 03 Sep 2025 21:16:02 +0000

Hi, my ecodan PUZ-WM112VAA is currently running on firmware version 5802, I was told that the latest version is 5809. Is there any ecodan installer that can apply to update to the outside unit?

Or if anyone knows how to install the update please let me know.

I obtained the firmware version number “5802” via running information code “090” in the service menu on ftc6 controller.

thanks

Just received an email telling me that my Ecodan ASHP requires a software update. Anybody else had this and confirm it isn't a scam of some sort please?

email is from: meu-uk.lesecodanquality@meuk

Hi - last week a Mitsubishi service tech installed a software update to our 11.2kW R32 unit. Apparently it alters the behaviour of the linear expansion valves (located above the accumulator), as a precaution to avoid a potential problem with noise due to oscillation of the valves. We don't have any experience of any such noise problems.

Guessing it could be the same update as the one that I just spotted you had mentioned here.

Mitsubishi were supposed to come on two previous occasions but cancelled at the last minute.

@abernyte, hmm, must have been a major disruption if 40% of users still can’t reconnect.

@editor No, they are being a tad coy. They just reassure that the Melcloud team are working hard on fixing the issue. No time to resolution available.

@editor thanks for that Mars. I’ve never had email contact with Mitsubishi before. The more I looked at it it did seem legit but one cannot be too careful these days, especially given there is mention in the email of confirming various details and that a Mitsi agent will require access to the outside and inside components.

Edit. I forgot to mention that a software update was applied at service Feb 2024.

Thanks again.

1000% – I regularly check and triple emails that look suspicious – you can never be too careful these days.

No but I am still not back connected. I am in the 40% who didn't reconnect automatically and are still being rejected by the authentication server

Have you established, or have Mitsubishi confirmed, what the cause of the issue is?

@Morgan then that looks legit to me, because the people I know and communicate with at Mitsubishi all use the same email address extension/domain: @meuk.mee.com

@editor it appears so. The address should be. meu-uk.lesecodanquality@meuk.mee.com
