I have just had my HP commissioned and i have an issue with the auto control. Currently I run the HP on auto from 03:00 to 10:00 and then 16:30 to 23:00. The house remains warm during the day so no need for the heating. I'm running on waterlaw when in auto. The problem is every time the HP starts in auto at 03:00 and 16:30, the controller gives a +5C offset to the waterlaw. I remove the offset, either by using the smart things app or the controller screen. However next auto time starts the +5C is added back in. I've looked through FSV settings and can't see anything that jumps out that I need to change. Any help really appreciated.

Suggest you have a trial with Havenwise app. I have the same ASHP and have been running HAvenwise for a year. Excellent system for me. You may find some help on the Facebook group for Samsung heat pump owners.

Agree with @broadsman , it seems many Samsung users are resorting to Havenwise.

There are a few threads on it and alternatives, like this one.

Hope it helps!
