1) EER and COP calculation is based in accordance to EN 14511.
2) Piping diameter under 100m for ultimate indoor unit / over 100m for ultimate indoor unit (if the longest piping equivalent length exceeds 100m, increase the sizes of the main tubes by 1 rank for gas tubes and liquid tubes).
3) If the following conditions are satisfied, the effective range is above 130% and below 200%: A. Obey the limited number of connectable indoor units. B. The lower limit of operating range for heating outdoor temperature is limited to -10°C WB (standard -25°C WB). C. Simultaneous operation is limited to less than 130% of connectable indoor units.
4) SEER / SCOP and ηs,c / ηs,h are in accordance with ErP test data for U2 type 4 way 90x90 cassette indoor units.
5) SEER / SCOP is calculated based on the seasonal space cooling / heating efficiency “η” values of the COMMISSION REGULATION (EU) 2016/2281. SEER, SCOP = (η + Correction) × PEF.
