Stand-by means the boiler must run to keep the water in its jacket and coil warm for when the demand occurs.
It is why the boiler runs in the summer when no one is using hot water... just keeping it ready for when it is needed.
So while the mini splits are keeping the house warm... the boiler must still run to keep the water in it within the set range.
