AUTO MODE
In the Auto mode, the temperature can be set to values between
62~86
F (17~30 ). In this mode, the machine chooses either
Cooling, Heating or Fan--only mode according to
Δ
T.
NOTE
:
Δ
T =T1--Ts, where T1 represents the indoor room
temperature and Ts represents the set temperature.

Heating
Indoor fan will run at an automatic fan speed for each running mode. The
louver will also operate depending in relevant mode taking place.
If the machine switches mode between heating and cooling, the
compressor stops for 15 minutes and then chooses a mode
according to
Δ
T.
If a new set temperature is commanded, the system chooses a
running mode according to
Δ
T.
FORCED OPERATION FUNCTION
When the machine is off, pressing the manual button carries the
machine to forced auto mode. Press the button once again, within
5 seconds, the machine turns to forced cooling mode. In forced
auto, forced cooling or any other operation mode, press the
manual button to turn the machine off. When in this mode, all
general protections and remote control functions are available.
Forced cooling mode:
The compressor runs at F2 frequency and indoor fan runs as
breeze. After running for 30 minutes, the machine turns to auto
mode with a 75
_
F (24
_
C) set temperature.
Forced auto mode:
The action of forced auto mode is the same as normal auto mode
with a 75
_
F (24
_
C) set temperature.
TIMER FUNCTION
Timing range is 24 hours.
The timer function will not change the system’s current operation
mode. The setting time is relative time.
Timer on
The machine turns on automatically when reaching the set time.
Timer off
The machine turns off automatically when reaching the setting time.
Timer on/off
The machine turns on automatically when reaching the set “on” time,
and then turn off automatically when reaching the set “off” time.
SLEEP MODE FUNCTION
Operation time in sleep mode is 7 hours. After 7 hours the system
turns off. The Operation process in sleep mode is as follows:
When in cooling mode, the set temperature rises 1.8
_
F (1
_
C) (up
to a maximum 86
_
F (30
_
C)) every one hour. Two hours later the
set temperature stops rising and indoor fan is fixed at low speed.

When the user uses timer off function in sleep mode (or sleep
function in timer off mode), if the timing is less than 7 hours, sleep
function will be cancelled when reaching the setting time. If the
timing is more than 7 hours, the machine will not stop until it
reaches the set time in sleep mode.
