Note
Only displays on auxiliary unit
Should there be no communication after 20 minutes from
when the unit is first powered up or no communication for
longer than 2 minutes after the 20 minutes initial power up
Once the unit has run for 10 minutes, the unit will allow a
discharge temperature of less than 15 degrees at a pressure
of more than 3.5MPa for 2 minutes. After 2 minutes the
unit will fault and will have to be powered off/ on to reset the
fault.

Must restart electrical power supply to unit to clear the fault
Must restart electrical power supply to unit to clear the fault
Must restart electrical power supply to unit to clear the fault
Indoor units communication lost for more than 3 munites;
Fault will no clear until the quantity of units are recovered
Air discharging pressure Pc ≤ 0.3MPa
Must restart electrical power supply to unit to clear the fault
Must restart electrical power supply to unit to clear the fault
X represents an auxiliary unit
Should 'P2' fault occur more than 3 times in 60 minutes, the
unit will then display 'H5' fault
X represents a system, 1 is A system, 2 is B system
Should 'P6' fault occur more than 3 times in 100 minutes,
the unit will then display 'H6' fault
X represents a system, 1 is A system, 2 is B system. Should
'P6' fault occur more than 3 times in 60 minutes, then the
unit will display a 'H4' fault. If 'H4' fault is displayed for more
than 10 minutes, then 'xP6' fault will be displayed
Should 'P9' fault occur more than 3 times in 60 minutes, the
unit will then display 'H9' fault
