Notes
(1) Nominal water flow rate for Dt: 10ºC
(2) Maximum water flow rate for Dt: 5ºC
(3) Sound level 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.
(4) Values are sound pressure values measured at all sides (front, back, left, right, top) at 1m distance. The values do not occur simultaneously on all mentioned sides.
(5) Sound levels are measured at: EW 55ºC; LW 65ºC; Dt 10ºC; ambient conditions 7ºCDB/6ºCWB
(6) Sound levels are measured at: EW 70ºC; LW 80ºC; Dt 10ºC; ambient conditions 7ºCDB/6ºCWB
(7) EW = entering water temperature - LW = leaving water temperature
(8) For details see operation range TW drawing. In combination EKHBRD*AC* + EMRQ* see EMRQ* operation range! -\> -15ºC
(9) Outdoor ambient, indoor ambient: 5ºC~30ºC
(10) European/International Technical Standard setting the limits for voltage changes, voltage fluctuations and flicker in public low-voltage supply systems for equipment with rated
current 75A.
