*
Power input of the compressor(s) at maximum unit operating conditions: entering/leaving evaporator water temperature = 15°C/10°C, maximum condensing temperature of
65°C, and 400 V nominal voltage.
**
Nominal unit current draw at standard conditions: evaporator entering/leaving water temperature 12°C/7°C, condenser entering/leaving water temperature 30°C/35°C. The
current values are given at 400 V nominal voltage.
*** Nominal unit current draw at standard conditions: evaporator entering/leaving water temperature 12°C/7°C, saturated condensing temperature (dew point) 45°C, subcooling 5
K. The current values are given at 400 V nominal voltage.
†
Maximum unit operating current at maximum unit power input and 400 V.
†† Maximum instantaneous starting current at 400 V nominal voltage and with compressor in across-the-line start (maximum operating current of the smallest compressor(s) +
locked rotor current of the largest compressor).
‡
Maximum instantaneous starting current at 400 V nominal voltage and with compressor with electronic starter (maximum operating current of the smallest compressor(s) +
reduced start-up current of the largest compressor).

Notes
The water pump power input values given are for guidance only.
BW05 units have an evaporator and a condenser pump.
•
To obtain the maximum unit power input for a unit with hydronic kit add the evaporator (*) and condenser pump (***) power input to the maximum power input of the unit
without hydronic module, given in the top table.
•
To obtain the maximum unit current draw for a unit with hydronic kit add the evaporator (**) and condenser pump current (†) draw to the maximum current draw of the unit
without hydronic module, given in the top table.
