(1) Values are guidelines only. Refer to the unit nameplate.
(2) In dB ref=10 -12 W, (A) weighting. Declared dualnumber noise emission values in accordance with EN 12102-1 (with an associated uncertainty of +/-2dB(A)) as required
by Ecodesign regulation and Eurovent certification. Measured in accordance with ISO 9614-1 at ErP C condition (A7/W55)
(3) In dB ref 20 μPa, (A) weighting. Declared dualnumber noise emission values in accordance with EN 12102-1 (with an associated uncertainty of +/-2dB(A)). For information,
calculated from the sound power level Lw(A) at ErP C condition (A7/W55).
(4) Min. water-side operating pressure with variable speed hydraulic module is 110 kPa.
(5) Heating Eurovent condition

(1) Power input, compressors and fans, at the unit operating limits and nominal voltage (data given on the unit nameplate).
(2) Maximum unit operating current at maximum unit power input and at 207 or 360 V.
(3) Maximum unit operating current at maximum unit power input and at 230 or 400 V (values given on the unit nameplate).
(4) Maximum instantaneous start-up current at operating limits (maximum operating current of the smallest compressor(s) + fan current + locked rotor current of the largest
compressor).
