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?

The other wall would probably have been much better. On top of that, the outdoor unit most likely sucks in its own cold air again, which reduces efficiency...
I would try removing the privacy screen from the fence and moving the trash bins to see if it gets quieter then.

I was just warned because my post apparently violated point 1.4 of the forum rules.
I’ll try again because I believe my recommendation does not violate the rules but actually addresses the original poster’s problem:
You have a flat roof, so placing the outdoor unit up there would be a good solution.

Is night setback really effective?In older buildings with radiators, yes. In new buildings with underfloor heating, it usually increases energy consumption because the heating system has to catch up and operates with a higher supply temperature.Mycraft schrieb:

I have disconnected the ERR. The set temperatures are 20°C (68°F) during the day and 18°C (64°F) at night. So, my question is whether this actually has any effect at the moment.
I will still try turning it off. If the heat pump responds to the settings even with the ERR disconnected, the load—and therefore the noise—should be lower in the morning.
KingJulien31 Jan 2022 16:28Your EER doesn't matter to your heat pump, whether it's disconnected or anything else. It operates independently of whatever you do with your EER.
Its heating demand is determined by the heating curve, meaning the outside temperature (AT), slope, and base point. The latter corresponds to your set temperatures.
