If the signal wire and power wire are cross-connected, all PCB will burn. • 3. The signal wires must be in different colour for different terminal in order to avoid misconnection of polarity. • 4. Check the address setting of the indoor unit:- • – Make sure the address settings are correct. • – Each indoor unit should have different address. • Outdoor unit checking:- • 1.
