ᐅ Outdoor heat pump unit very noisy – possible solutions? Quiet mode? Effects?

Hello,
the outdoor unit of our Elco Aerotop Split 07 air-to-water heat pump is quite loud.
The outdoor unit is located very close to the neighbor’s property, and they have started to complain. I can understand this, as I also find the unit very noisy.
Other units in our new housing development are noticeably quieter.
Are there any ways to reduce the noise level of the outdoor unit? It would probably also help if the unit did not turn on as frequently.
I found one option in the manual:
Silent mode (if available): This function limits the performance of the heat pump system to reduce noise. WARNING: Activating this function limits the maximum output of your heat pump to about 70%, which may result in insufficient heating capacity.
What effects does this have? Does it increase energy consumption, or is this mode harmful to the system? Obviously, I want to avoid the latter. To compensate for the 30% reduction, I would probably need to adjust other settings? Which parameters would those be?

What I find strange is that the device runs almost continuously throughout the entire day and night.Well, on one hand, that's optimal, but on the other hand, there won't be any performance left to throttle. Maybe @Alessandro’s suspicion is correct after all.

What I find strange is that the device runs almost all day and throughout the night. Despite night setback and buffer tank.That's fine. But remove the night setback. It’s counterproductive. Better to let it run slowly than have it run at full power (= noisy) in the morning to make up for the temperature lost overnight.A

It’s perfect. But remove the nighttime setback. It’s counterproductive. It’s better to run it slowly than to have it work at full power (= loud) in the morning to catch up on the temperature lost overnight. Does the nighttime setback even make a difference? I have disconnected the ERR. The room temperature on the heat pump is set to 20°C (68°F) during the day and 18°C (64°F) at night.

The neighbor’s window is 3 meters (10 feet) behind the fence. However, the unit was already there when they started building, and at that time there was no fence yet.
If we hang the unit under their lamp, I’m worried it will be even louder for us.
