Hello!
I'll start.
Heated area 200m2 (2,153 sq ft)
KfW 55 standard
Mechanical ventilation with heat recovery
Current outdoor temperature 6°C (43°F)
Heating energy consumption including hot water 35 kWh
Electricity consumption 9 kWh
COP 3.88

KingJulien15 Nov 2021 19:46Alright, it's fine already. My Lwz_5_s_plus runs minimally at 0.4kW at 20Hz when it's settled down.
I’m not familiar with yours, but since it's the same manufacturer:
I’m not familiar with yours, but since it's the same manufacturer:
- Maximum integral part
- Possibly reduce the proportional part
- “Heating design” set as low as possible (e.g., 50%)
- Design temperature as low as possible (max. NAT, or try minimum occasionally)

Try and analyze 😉The design temperature is already set to -20. Unfortunately, I can’t adjust the other options.
