An oversized heat pump leads to short cycles. However, if the underfloor heating system behind it is reasonably well adjusted, this should not necessarily lead to a "short circuit" that would cause the return flow to spike, thus incorrectly ending the cycle too early and then turning on again shortly afterwards after the return flow drops.
yes, also.
The consequence of improper adjustment can be that the hysteresis becomes too small.
This can happen if you want to keep the supply temperature as exact as possible.
But this is not necessary! It may well fluctuate a few degrees between the switch-on and switch-off point.
Maybe a few more liters of water can also fit into the heating circuit?!?
(well vented?)
Therefore, I would try to figure out which setting causes the small
hysteresis and increase it accordingly.
