Functions and Control
Domestic air conditioner
*Indoor fan control
manual control: You can choose high, medium, low and automatic speed control.
Automatic: When Tr<Ts, high speed.
When Ts≤Tr≤Ts+2℃, medium speed.
When Tr> Ts+2℃, low speed.
When the airflow speed has no delay from the high to low switching, the speed should be delayed for 3
minutes (remain at high speed for 3 minutes.) before the next switch.
*Airgate location control: the location for the airgate can be set according to your needs.
Coldair proof operation
1. The indoor operation within 4 minutes after the start up is as the following diagram, the air speed can be
raised only after the speed has reached a certain level.
Set speed
Heat start temp 1
Low speed
Heat start temp 2
Light speed
Heat start temp 3
Fan/off
Heat start temp 4
Fan/off
2. 4 minutes after the start up of the indoor fan, the light airflow and the low airflow will be turned to the set
speed airflow.
3. In the cold air proof operation, the fan won’t stop after the start up.
4. During the cold
air pr
oof operation, the indoor system will continuously send ‘indoor high speed’ signals to
the outdoor system.
* Residue heat sending. The indoor fan will send the residue heat at a low speed for 12 seconds.
If other conditions are satisfied, when the compressor stops, the indoor system will operate at a light speed.
The indoor fan will stop when the coil temperature is below the ‘heat start temp 4’.
* Defrosting. When the system receives the defrosting signal from outdoors, the indoor fan will stop and the
indoor temperature display won’t change. At the time, any indoor coil malfunctions will be neglected. When
the outdoor defrosting finishes, the coil malfunction will still be neglected until the compressor has been
started up for 30 seconds. The indoor temperature display will not change and the system operates at the
cold air proof mode.
* Automatic heating temperature compensation: when the system enters the heating mode, the temperature
compensation (4) will be added. When the status is switched off, the compensation will be erased.
7.1.5 Strength operation
The system enters the mode after receiving the ‘strength signal’.
Send strength operation signal to the outdoor system.
The mode change finishes the strength operation.
Entering ‘mute’, you can have normal operation or signal control such as timing to finish the strength
operation.
Keep the high
speed. The fan
doesn’t stop
