2, the compressor and the outdoor motor will run continuously, indoor motor will run at the set
speed, this area is dened as Area A;
0≤ΔT≤2, the compressor and the outdoor motor will always run for 10 minutes and then stop for 6
minutes, indoor motor will be LOW speed, this area is dened as Area B;
ΔT
＜
0, the compressor and the outdoor motor will stop, indoor motor will run at Low speed, this
area is dened as Area C.
(2) After the unit is running in DRY mode, the system will change over among Area A, Area B, and
Area C (the conversion temperature difference ±1
℃
)
If the system is in Area A, when ΔT
＜
1, change to Area B; If the system is in Area C, when ΔT>1,
change to Area B; If the system is in Area B, when ΔT>3, change to Area A; WhenΔT
＜－
1, change
to Area C.
3.5 FAN mode control
The compressor and the outdoor motor will stop running, indoor motor can be set at high/med/low
speed, the fan blade can swing or stay at one position. In this mode, you can set the TIMER and
SLEEP function.
3.6 HEAT mode control
(1) 4-way valve control
a. 4-way valve being electried after compressor has started for 3 seconds when heating for the rst
time, then the 4-way valve will be electried before compressor start;
b. Only in COOL / DRY/ FAN (not heating) mode, 4-way valve and compressor will power off at the
same time, the 4-way valve keeps being powered when shutoff, thermostat OFF and compressor
stop.
Note: 4-way valve control is realized by outdoor unit for the unit with outdoor PCB, not concurrent
completely.
(2) In heating mode, for every time the compressor startup (thermostat ON), within 6 minutes, the
4-way valve will not be limited by the temperature sensor, but for the set temperature change, shutoff
signal and the protection, the compressor can stop immediately without 6-minute limitation.
(3) ΔT≥1 compressor running, indoor motor runs at anti-cold air mode;
ΔT≤-1 compressor stops, indoor motor runs at blowing remaining heat mode;
-1<ΔT<1 compressor retains original state
(4) Overheat protection
In heating mode, compressor has started up and indoor motor has run for over 30 seconds, if indoor
coil temperature Tg>60
℃
, outdoor motor will stop; if Tg<56
℃
, and outdoor motor has stop for 45
seconds, outdoor motor will run again; if Tg>68
℃
lasts 10 seconds, the compressor will stop and
indoor motor will run in thermostat OFF. After the compressor stops for 9 minutes and Tg reduces to
48
℃
, the compressor and the outdoor motor will run again.
