No, apparently the UK Samsung technical don’t get to see any FW change logs themselves 🙄

I have a AE050RXYDEG-EU heat pump.

All I know is that updating my indoor controller MIME03CN (DB91-02103B) to 220614 seem to fix my pump PWM. It wasn’t modulating at all before, now it’s modulating correctly 🙂

My Main Micom (DB91-02091B) is running firmware 190704, the latest firmware for this is  
221130. However, without a changelog and because my HP is working well, I’m a bit hesitant to update. There’s no path to roll back without involving Samsung support. I’ll probably do it in the Spring when HP operation is less critical!

The FW files can be downloaded from [https://partnerhub.samsung.com](https://partnerhub.samsung.com) with an installer login.
