the compressor will have 3 minutes delay when
restarts.
6.4.10 Louver Position Memory Function
When starting the unit again after shutting down,
its louver will restore to the angle originally set
by the user, but the precondition is that the angle
must be within the allowable range, if it exceeds,
it will memorize the maximum angle of the louver.
During operation, if the power fails or the end
user shuts down the unit in the turbo mode, the
louver will restore to the default angle.
6.4.11 8
℃
Heating(optional)
In heating operation, the preset temperature of
the air conditioner can be as lower as 8
℃
, which
keeps the room temperature steady at 8
℃
and
prevents household things freezing when the
house is unoccupied for a long time in severe
cold weather.
6.4.12 Follow me
1) If the indoor PCB receives the signal which
results from pressing the FOLLOW ME button on
remote controller, the buzzer will emit a sound
and this indicates the follow me function is
initiated. But when the indoor PCB receives
signal which sent from remote controller every 3
minutes, the buzzer will not respond. When the
unit is running with follow me function, the PCB
will control the unit according to the temperature
from follow me signal, and the temperature
collection function of room temperature sensor
will be shielded, but the error detective function
of room temperature sensor will be still valid.
2) When the follow me function is available,
the PCB will control the unit according to the
room temperature from the remote controller
and the setting temperature.
3) The PCB will take action to the mode
change information from remote controller signal,
but it will not affected by the setting temperature.
4) When the unit is running with follow me
function, if the PCB doesn’t receive any signal
from remote controller for 7 minutes or pressing
FOLLOW ME button again, the follow me
function will be turned off automatically, and the
temperature will control the unit according to the
room temperature detected from its own room
temperature sensor and setting temperature.
6.4.13 Mode conflict
The indoor units cannot work cooling mode and
heating at same time.

6.4.13.2 Unit action
 Suppose Indoor unit A working in cooling
mode or fan mode, and indoor unit B is set
to heating mode, then A will change to off
and B will work in heating mode.
 Suppose Indoor unit A working in heating
mode, and indoor unit B is set to cooling
mode or fan mode, then B will change to
stand by and A will be no change.
