# GLOBAL - Altherma Global - ULTIMATE SYSTEM COP
# ======================
# DOEL:
# De meest accurate systeem-efficiëntie berekening mogelijk voor Daikin Altherma 3.
# Berekent de werkelijke "System COP" (wat je betaalt vs. wat je krijgt).
#
# METHODE (v2.5.x):
# In plaats van te schatten hoeveel warmte de BUH toevoegt, meten we dit nu fysiek.
# • Thermische Output: Gemeten via sensor NA de backup heater.
# • Elektrische Input: Som van Compressor + Backup Heater.
#
# FORMULE:
# COP = (Flow × 0.0696 × ΔT_System) ÷ (Elektrisch_Comp + Elektrisch_BUH)
# * ΔT_System = (Temp NA BUH - Retour Temp)
#
# FEATURES:
# 1. Hybrid Measurement: Meet correct of de warmte van de compressor, de BUH, of beide komt.
# 2. 12kW Tuning: Ondersteunt flow rates tot 60 L/min (standaard sensoren kappen af op 25).
# 3. Partial Load Capture: Ondersteunt CoP tot 8.0 voor mild weer/deellast.
# 4. Defrost Detectie: Zet CoP op 0.0 tijdens ontdooien (geen nuttige warmte).
# 5. Directe Feedback: Geeft direct inzicht in impact van BUH op rendement.
# 6. Volledige Attributen: Behoudt alle dashboard-data (Volt, Amp, Flow, Modus, etc.).
#
# TYPISCHE WAARDEN (12kW Model):
# • Compressor only: CoP 3.5 - 6.0
# • Hybrid (Comp + BUH): CoP 2.0 - 3.0 (Tijdens SWW of extreme kou)
# • Defrost: CoP 0.0
#
# VERSION HISTORY:
# v2.5.3 - FIX: Power calculation consistency - use direct power sensor instead of calculated
# v2.5.2 - Added Performance Guidelines to calculation note
# v2.5.1 - Restored all original attributes with updated logic
# v2.5.0 - ULTIMATE: Overstap naar fysieke meting NA BUH (geen schattingen meer)
# v2.4.0 - System Efficiency: BUH elektrisch meegerekend in input
# v2.3.3 - Toegevoegd: Equipment Model informatie in attributen
# v2.3.2 - Fix: Scope errors in attributen opgelost
# v2.3.1 - Fix: Flow limiet verhoogd naar 60 L/min voor 12kW unit
# v2.3.0 - Toegevoegd: Outdoor temperatuur context
# v2.2.0 - Toegevoegd: BUH detectie en power stability check
# v2.0.0 - Major rewrite met universele ΔT validatie
