CONTROL SYSTEM
IFAN speed depends on the indoor coil temperature
Anti-cold air function
When starting the heating mode, anti-cold air function will be activated and IFAN can run at low
speed or stop running. This function will terminate after the unit runs for 2min or the ICT reaches 40
degree.
Residual heat blowing function
During heating, when the stopping condition for the COMP is reached, the COMP and OFAN stop
running while the louver moves to position L. The IFAN will stop after running for 60s at setting
speed.
11.5 Auto Cool/Heat Mode
In AUTO mode, the system selects the running mode (COOL/HEAT/FAN) automatically according
to the room temperature. The display shows the actual running mode and setting temperature.
There will be 30s delay for mode conversion.
1. When RAT≥25 degree, the cooling mode is selected.
2. When RAT≤20 degree, the unit runs in heating mode
3. When 20 degree <RAT< 25 degree, upon initial startup, the unit will enter auto mode and run in
automatic fan mode. If the other mode changes into auto mode, the previous running mode will
remain.
11.6 Dry Mode
If RAT≥SPT+2, the unit starts cooling operation. In this case, the COMP and OFAN will operate and
the IFAN will run at the low speed.
If RAT≤SPT-2, the COMP and OFAN will stop. While IFAN will run at low speed.
If SPT-2＜RAT≤SPT+2, While IFAN will run at low speed. COMP and OFAN will operation in 6 min
ON and 4 min OFF in cycling.
In this mode, the RV will be OFF and the temperature setting range is 16~30.

11.7 Louver Control
After power on, the up and down swing louver will automatically
open and then close completely.
In heating mode, if the swing function is not set, the up and down
louver will rotate to maximum in clockwise direction. Then it will
rotate to position D. Under other states, the upper and lower air
deflector will rotate to level L.
If the swing function is set when starting the unit, the louver will
swing between Position L and D. there are 7 states for louver: in
position L, A, B, C, D, and swing between L and D, stop in any
place between Position L and position D. When the unit is turned
