Three-Phase Rotation Check

On NSYCU••••3P4•DG cooling units with a three-phase power supply, the order of the phases L1, L2 and L3 is checked by the thermostat. If the phase order is incorrect, the oPd alarm code is displayed the first time the cooling unit is powered on. In this case, the wiring must be corrected as indicated in the wiring diagram.
