I honestly dont know. Mitsubishi seem to have a fairly similar modulation ratio, but those pumps are, I think, also constant flow (like Vaillant the ...
Really - thats terrible. If it cant be changed in the UI its a very good argument not to buy a Samsung Gen 6 heat pump!
Sensible. After you have done that perhaps consider what is triggering reheat. It looks like its DHW tank temperature alone not a timer plus DHW t...
