Wrong wiring done. Power supply input should be taken from outdoor unit from LN¥pins, not from the indoor 123¥ pins. Also the wiring tip should be rounded at the nuts, not straight.
@@UDAYTECH001 Only daikin has input power supply to the outdoor unit via 3 core wire 2.5mm² recommended & from outdoor to indoor 4 core wire 1.5mm² which was included with the pipes. What was the installation cost???
