Remark:
1. Must not connect the power cable and communication wire incorrectly. Forbidden to connect
the power cable and communication wire with one muti-core cable, and they must be wired
separately, keep proper distance between them to ensure the air conditioner run normally.
2. Communication wires among indoor units should be hand in hand type, and decrease the
branch, also the shielded layer should be connected together and be earthed on one point.
3. All indoor communication wires will be connected to the communication bus wire (2-core), C1
and C2 are non-polar.
4. Because the indoor unit adopts EEV control method, when a sudden power off occurs, the
EEV maybe keep some angle. If indoor unit and outdoor unit connect to power supply
separately, when some indoor units running in cooling mode, when powered off, because
the EEV does not reset, the indoor units maybe drop water, or ice up. We recommend that the
indoor unit connect to power supply from the outdoor unit, or use one power supply with the
outdoor unit. If the indoor unit need connect power supply individually, the personnel must
explain to the customer that he (she) must switch off the unit with wired controller or remote
controller, then he (she) can shut off the indoor unit. If there is accidental power failure,
please firstly power on all the indoor units after power on, in order to reset the indoor EEV.
5. When wiring the MP2A or MP3A, please ensure that the power source and the communication
wires of MP2A or MP3A must correspond with the relative indoor units.
6. AS*FCBHA and the cassette unit will not be connected with the MP2A or MP3A.
7. If the ceiling concealed indoor unit is with the electric heater, the circuit breaker will vary
accordingly.
