8.4.4 Auto-mode
This mode can be chosen with remote
controller and the setting temperature can be
changed between 17°C(62.6°F)~30°C(86°F).
In auto mode, the machine will choose cooling,
heating or fan-only mode according to ΔT
(ΔT =T1-Ts).
T1-Ts
Cooling
Heating*
Fan only
Heating*: For cooling only models, they will run
at fan speed
Indoor fan will run at auto fan of the relevant
mode.
The louver operates same as in relevant mode.
If the machine switches mode between heating
and cooling, the compressor will keep stopping
for certain time and then choose mode
according to T1-Ts.
If the setting temperature is modified, the
machine will choose running function again.
8.4.5 Drying mode
8.4.5.1 Indoor fan speed is fixed at breeze and
can’t be changed. The louver angle is the same
as in cooling mode.
8.4.5.3 Low indoor room temperature protection
In drying mode, if room temperature is lower
than 10°C(50°F), the compressor will stop and
not resume until room temperature exceeds
12°C(53.6°F).
8.4.5.4 Evaporator anti-freezing protection,
condenser high temperature protection and
outdoor unit frequency limit are active and the
same as that in cooling mode.
8.4.5.5 The outdoor fan operates the same as
in cooling mode.
8.4.6 Forced operation function
8.4.6.1 Enter forced operation function:
When the machine is off, pressing the touch
button will carry the machine to forced auto
mode. If pressing the button once again within
5 seconds, the machine will turn into forced
cooling mode.
In forced auto, forced cooling or any other
operation mode, pressing touch button will turn
off the machine.
8.4.6.2 In forced operation mode, all general
protections and remote control are available.
8.4.6.3 Operation rules:
Forced cooling mode:
The compressor runs at F2 frequency and
indoor fan runs as breeze. After running for 30
minutes. the machine will turn to auto mode as
24°C(75.2°F) setting temperature.
Forced auto mode:
The action of forced auto mode is the same as
normal auto mode with 24°C(75.2°F) setting
temperature.
8.4.7 Auto-Restart function
The indoor unit is equipped with auto-restart
function, which is carried out through an
auto-restart module. In case of a sudden power
failure, the module memorizes the setting
conditions before the power failure. The unit will
resume the previous operation setting (not
including swing function) automatically after 3
minutes when power returns.
If the memorization condition is forced cooling
mode, the unit will run in cooling mode for 30
minutes and turn to auto mode as 24°C(75.2°F)
setting temp.
If AC is off before power off and AC is required
to start up now, the compressor will have 1
minute delay when power on. Other conditions,
the compressor will have 3 minutes delay when
restarts.
