@mike-h - can you possibly point me towards any advice on how to install iBoost with a Samsung Gen 6 ashp? I have searched the forums, but can't find out whether to wire iBoost directly to the immersion, or disconnect immersion from Samsung, before connecting iBoost? Flumoxed (I have a qualified electrician trying to sort this for me). Thanks in advance 😁

Hi, the immersion was disconnected from Samsung and the iBoost directly connected to the immersion instead. Therefore there is no connection between the Samsung and the iBoost. You can set it to do your legionella sterilisation at periodic intervals should you wish, so there is no loss in functionality.

Many thanks@mike-h - so disconnect the immersion from the Samsung, and connect the iBoost directly to the immersion.. Can I assume that the Samsung won't throw an error message, when it can't find an immersion connected e.g. during the legionella cycle? (Many thanks for your time 🙂)

I would disable the legionella sterilisation (FSV 3041) and there shouldn't be any error messages then. I don't have any.

@mike-h as an alternative, instead of turning off the legionella altogether, does the CP allow you to change the set point temperature for legionella cycles? You could then, for example, change that to 10C, so the heat pump would always be "satisfied".

The minimum set point for legionella on the Samsung is 40C, so this would not work. However, I don't follow your logic in looking for an alternative to turning legionella off on the Samsung. The Samsung has to be disconnected from the immersion. The iBoost takes over all immersion heating, whether from excess solar power or should you wish to do so, from the grid.
