Notes
(1): for ΔT = 10°C
(2): for ΔT = 5°C
(3): The data mentioned is valid in free field condition because it is measured in a semi-anechoic room. Measured value under actual installation conditions will be higher due to environmental
noise and sound reflections. These values are sound pressure levels measured at all sides (front / back / left / right / top) at 1m distance (see engineering data book for more details). The values
do not occur simultaneously on all mentioned sides
(4): EW = entering water temperature - LW = leaving water temperature
(5): for details see operation range TW drawing
(6): for DHW operation
