7.4.3.5 Evaporator coil temperature protection
7.4.4 Auto-mode
This mode can be chosen with remote controller
and the setting temperature can be changed
between 17˚C~30˚C.
In auto mode, the machine will choose cooling,
heating or fan-only mode according to ΔT (ΔT
=T1-Ts).

Heating
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 15
minutes and then choose mode according to T1-Ts.
If the setting temperature is modified, the
machine will choose running function again.
7.4.5 Drying mode
Indoor fan speed is fixed at breeze and can’t be
changed. The louver angle is the same as in cooling
mode.
All protections are active and the same as that in
cooling mode.
7.4.6 Forced operation function
Forced cooling mode:
The compressor and outdoor fan keep running and
the indoor fan runs at low speed. After running for 30
minutes, AC will turn to auto mode with 24˚C setting
temperature.
Forced auto mode:
The action of forced auto mode is the same as normal
auto mode with 24˚C setting temperature.
When AC receives signals, such as switch on, switch off,
timer on, timer off, mode setting, fan speed setting,
sleeping mode setting, follow me setting, it will quit the
forced operation.
7.4.7 Timer function
7.4.7.1 Timing range is 24 hours.
7.4.7.2 Timer on. The machine will turn on automatically
when reaching the setting time.
7.4.7.3 Timer off. The machine will turn off automatically
when reaching the setting time.
7.4.7.4 Timer on/off. The machine will turn on
automatically when reaching the setting “on” time, and
then turn off automatically when reaching the setting
“off” time.
7.4.7.5 Timer off/on. The machine will turn off
automatically when reaching the setting “off” time, and
then turn on automatically when reaching the setting
“on” time.
7.4.7.6 The timer function will not change the AC current
operation mode. Suppose AC is off now, it will not start
up firstly after setting the “timer off” function. And when
reaching the setting time, the timer LED will be off and
the AC running mode has not been changed.
7.4.7.7 The setting time is relative time.
7.4.7.8 The AC will quit the timer function when it has
malfunction.
7.4.8 Economy function
7.4.8.1 The sleep function is available in cooling, heating
or auto mode.
7.4.8.2. Operation process in sleep mode is as follows:
When cooling, the setting temperature rises 1˚C (be
lower than 30˚C) every one hour, 2 hours later the
setting temperature stops rising and the indoor fan is
fixed at low speed.
When heating, the setting temperature decreases 1˚
C
(be
higher than 17˚C) every one hour, 2 hours later the setting
temperature stops rising and indoor fan is fixed at low
speed. (Anti-cold wind function has the priority).
