Samsung Gen 6 8kW Efficiency

Hi Glyn, did you that if you set 20 it reached this temp, it’s off until it drops to 19 and then turn on right ? Still I don’t understand why there is no hysteresis possible to set on this controller. E.g. 0.5C. 1C is pretty big drop you may fell.

I agree, it’s a shame the hysteresis is not adjustable. But I can’t see an option for this. 1C of hysteresis does not bother me, this makes for decent length runtimes.

Could you please reattach the video ? It was removed.

Here’s my video about my heat pump:

the way mine behaves, if set to 21.0, is this:
call for heat constantly until temperature reaches 21.9. switch off. house cools to 20.9. switch back on.
so the hysteresis for me, is +0.9 -0.1 . that is if there is no short cycling of course, if its in stable output.

Interesting, mine defiantly has a 1C hysteresis. It’s quite possible there are differences between different firmware versions. This is my indoor temperature as measured by the controller, I’m reading the modbus output.
