2.3 Fan Mode
When fan mode is activated:
• The outdoor fan and compressor cease operation.
• Temperature control is disabled and no temperature
setting is displayed.
• The indoor fan speed can be set to high, medium, low,
or auto.
• The louver operations are identical to those in cooling
mode.
2.4 Cooling Mode
2.4.1 Indoor Fan Control
• In cooling mode, the indoor fan operates continuously.
The fan speed can be set to high, medium, low or auto.
• The auto fan acts according to the value of T1-TS.
2.4.2 Outdoor Fan Control
• The outdoor fan is controlled by T4.
2.4.3 Evaporator Temperature Protection
When T2<4°C for 250 seconds or T2<0°C, the compressor
and outdoor fan cease operation and resume to normal
when T2>8°C and the time of protection is no less than 3
minutes.
2.4.4 Condenser Temperature Protection
When condenser temperature is more than setting value,
the compressor ceases operations.
2.5 Heating Mode(Heat pump models)
2.5.1 Indoor Fan Control
• When the compressor is on, the fan speed can be set
to high, medium, low, or auto. And the anti-cold wind
function has the priority.
• The auto fan acts according to the value of T1-Ts.
2.5.2 Outdoor Fan Control
• The outdoor fan is controlled by T4.
2.5.3 Defrosting mode
• The unit enters defrosting mode according to the
value of temperature of T3 and the value range of
temperature change of T3 and also the compressor
running time.
• If any one of the following items is satisfied, the
defrosting will finish and the machine will turn to
normal heating mode.
• T3 rises to be higher than TCDE1°C.
• T3 keeps to be higher than TCDE2°C for 80
seconds.
• The machine has run for 10 minutes in defrosting
mode.
2.5.4 Evaporator Temperature Protection
When the evaporator temperature exceeds a preset
protection value, the compressor and outdoor fan cease
operations, the outdoor fan motor ceases operation 30
seconds later.
2.5.5 Prevent Over-Heating
In heating mode, when the indoor unit has no capacity
requirement due to indoor room temperature increased,
the Indoor fan will run in super breeze. (Anti-cold wind
function has the priority)
2.6 Auto Mode
• This mode can be selected with the remote controller
and the temperature setting can be adjusted between
17°C~30°C
• In auto mode, the machine selects cooling, heating, or
fan-only mode on the basis of △T (△T =T1-Ts).
∆T Running mode
∆T>2°C Cooling
-2°C≤∆T≤2°C Fan-only
∆T<-2°C Heating*
Heating*: In auto mode, cooling only models run the fan.
• Indoor fans run at the auto fan speed of the relevant
mode.
• The louver operates the same as in relevant mode.
• If the machine switches mode between heating and
cooling, the compressor pauses for a certain period of
time intermittently and then selects a mode based on
T1-Ts.
• If the setting temperature is modified, the machine
selects a new running function.
2.7 Drying Mode
• Indoor fan speed is fixed at low and cannot be
changed.
• Low indoor room temperature protection
• In drying mode, if room temperature is lower than
10°C, the indoor fan will stop and not resume until
room temperature exceeds 12°C.
• All protections are activated and operate the same as
they do in cooling mode.
• The louver operates the same as in cooling mode.
