Instantaneous start-up current (operating current of the smallest compressor + fan current + locked rotor current in star connection of the largest compressor). Values obtained at
operation with maximum unit power input.
** 30XA 1402 to 1702 units: circuit 1 supplies circuits A and B, circuit 2 supplies circuits C and D. 30XA 1112, 1212, 1312 and 1382 units: circuit 1 supplies circuit A, circuit 2 supplies
circuit B.
*** Instantaneous start-up current (operating current of the smallest compressor + fan current + locked rotor current in star connection of the largest compressor). Values obtained at
standard Eurovent unit operating conditions: air 35 °C, water 12/7 °C.
**** Values obtained at operation with maximum unit power input.
