3.5High efficient run function
In the heating (except for the single cooling unit), cooling or dehumidifying mode, it
may be set for high efficient run with the indoor fan speed changed to the high
efficient fan speed and the compressor operating at the highest frequency as
available. If the display screen can display the frequency, the frequency displayed
on the screen is up to the maximum. It will restore to the previous run state after
15 minutes operation automatically.
3.6 Automatic run mode
If there is no man-machine communication function after the unit is started, the
indoor fan operates at the ultra-low flowrate for 20 seconds before selecting a run
mode; The room temperatures are detected during this period for the selection of
a run mode.
In the first operation:
a.
When T
room
– T
set
>
3
℃
,
it starts in the cooling mode;
b.
When -3
℃
≤
T
room
– T
set
≤
3
℃
,
it starts in the ventilation run mode;
c.
When T
room
– T
set
<
-3
℃
, it starts in the heating mode.
After the first run in the cooling or heating mode, the mode will be changed as the
following:
a.
When T
room
– T
set
>
3
℃
, it will be changed to the cooling mode;
b.
When T
room
– T
set
<
-3
℃
, it will be changed to the heating mode;
c.
When these conditions are not met, it will remain in the previous run mode.
When the temperature setting is changed, re-judgment will be made for the run
mode according to the descriptions mentioned above; when the compressor is
halted for 10 minutes, the re-judgment will be made for the run mode.
