Hi Glyn. Do I recall you mentioning the MIM-C02N for ASHP monitoring (but dismissing it as not very helpful except for initial commissioning)? It’s expensive (£200 from Midsummer) but looking at the manual it looks like it might be useful to understand some of the Samsung controller algoithms. …

[image] Ian_Calderbank: I was wondering how you did it! have samsung tech given you any meaningful info about different firmware version behaviours? No, apparently the UK Samsung technical don’t get to see any FW change logs themselves :roll_eyes: I have a AE050RXYDEG-EU heat pump. All I kn…

Hi Glyn, is there any way of updating the firmware without buying the dongle? I’d have to get my hands on a windows pc as well, so it would be a significant expense just for an update of firmware

No, dongle is essential as far as I know for FW update. sent from my mobile device

Hi Glyn. Finally connected the C02N today :slightly_smiling_face:. The spreadsheet shows Main Micom version DB91-02450A 220706 and EEPROM version DB82-07081A 220622. Are these the latest as far as you know? (The online manual is not very helpful about FW updates…) Thanks, Sarah

Hello Glyn, On the Partnerhub site is a Service Bulletin for my unit. Do you know what it means? Is it like a recall?

@glyn.hudson I now believe those were not defrosts but frost prevention cycles - see the “When is a defrost not a defrost?” thread.

Hi all, I’m new to this forum but I’ve read a lot of very interesting stuff here so decided to sign in ! I have been playing with my Samsung AC100 ducted unit and was searching also for a way to monitor and perform maintenance. Samsung MIM-C02N was the official way to go but a bit expensive especi…
