---0℃≤T2<4℃, the compressor frequency is limited and
decreases to a lower level
---4℃≤T2<7℃, the compressor maintains its current
frequency.
---T2>7℃, the compressor frequency is not limited.
1.5.4 Condenser Temperature Protection
When condenser temperature is more than setting value,
the compressor ceases operation.
1.6 Heating Mode(Heat pump models)
1.6.1 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-Td.
1.6.2 Outdoor Fan Control:
• For 12k:The outdoor fan is controlled by T4 and
compressor frequency.
• For other models: The outdoor fan is controlled by T4.
1.6.3 Defrosting mode
• The unit enters defrosting mode according to the value
of temperature of T3 & T4 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.
• T3 keeps to be higher than TCDE2 for 80 seconds.
• The machine has run for 10 minutes in defrosting
mode.
1.6.4 Evaporator Temperature Protection
When the evaporator temperature exceeds a preset
protection value, the compressor ceases operation, the
outdoor fan motor ceases operation 30 seconds later.
1.7 Auto Mode
• This mode can be selected with the remote controller
and the setting temperature can be changed 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℃ Cooling
-2℃≤∆T≤2℃ Fan-only
∆T<-2℃ 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
∆T.
• If the setting temperature is modified, the machine
selects a new running function.
1.8 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.
1.9 Timer Function
• The timing range is 24 hours.
• Timer On. The machine turns on automatically at the
preset time.
• Timer Off. The machine turns off automatically at the
preset time.
• Timer On/Off. The machine turns on automatically at
the preset On Time, and then turns off automatically
at the preset Off Time.
• Timer Off/On. The machine turns on automatically at
the preset Off Time and then turns off automatically at
the preset On Time.
• The timer does not change the unit operation mode.
If the unit is off now, it does not start up immediately
after the “timer off” function is set. When the setting
time is reached, the timer LED switches ioff and the
unit running mode remains unchanged.
• The timer uses relative time, not clock time
1.10 Sleep Function
• The sleep function is available in cooling, heating, or
auto mode.
• The operational process for sleep mode is as follows:
• When cooling, the temperature rises 1°C (to not
higher than 30°C) every hour. After 2 hours, the
temperature stops rising and the indoor fan is fixed
at low speed.
• When heating, the temperature decreases 1°C(to
