(1) Maximum instantaneous start-up current at operating limit values (maximum operating current of the smallest compressor(s) + fan c locked rotor current of the
largest compressor).
(2) Power input, at the unit permanent maximum operating conditions (data given on the unit nameplate).
(3) Standardised Eurovent conditions: water heat exchanger entering/leaving water temperature 12°C/7°C, outside air temperature 35°C.
(4) Maximum unit current at 400 V, non permanent operating conditions (values given on the unit nameplate).
† Maximum unit operating current at 360 V, non permanent operating conditions.
