• Descent curve
• When T1-Tsc is lower than or equal to 0.5°C, fan
speed increases to 40%(Low);
• When T1-Tsc is lower than or equal to 0°C, fan
speed increases to 60%(Medium);
• When T1-Tsc is lower than or equal to -1.5°C, fan
speed increases to 80%(high);
• When T1-Tsc is lower than or equal to -3°C, fan
speed increases to 100%(High)..
3.5.3 Outdoor Fan Control:
Case 1:
• The outdoor unit will be run at different fan speed
according to T4 and compressor frequency.
• For different outdoor units, the fan speeds are
different.
Case 2:
• The outdoor unit will be run at different fan speed
according to T4.
• For different outdoor units, the fan speeds are
different.
3.5.4 Defrosting mode
Case 1:
• The unit enters defrosting mode according to the
temperature value of T3 and T4 as well as the
compressor running time.
• In defrosting mode, the compressor continues to run,
the indoor and outdoor motor will cease operation,
the defrost light of the indoor unit will turn on, and
the “ ” symbol is displayed.
• If any one of the following conditions is satisfied,
defrosting ends and the machine switches to normal
heating mode:
• T3 rises above TCDE1.
• T3 maintained above TCDE2 for 80 seconds.
• Unit runs for 15 minutes consecutively in defrosting
mode.
• If T4 is lower than or equal to -22°C and compressor
running time is more than TIMING_DEFROST_TIME,
if any one of the following conditions is satisfied,
defrosting ends and the machine switches to normal
heating mode:
• Unit runs for 10 minutes consecutively in defrosting
mode.
• T3 rises above 10°C.
Case 2:
• The unit enters defrosting mode according to the
temperature value of T3 as well as the compressor
running time.
• In defrosting mode, the compressor continues to run,
the indoor and outdoor motor will cease operation,
the defrost light of the indoor unit will turn on, and
the “ ” symbol is displayed.
• If any one of the following conditions is satisfied,
defrosting ends and the machine switches to normal
heating mode:
• T3 rises above TCDE1.
• T3 maintained above TCDE2 for 80 seconds.
• Unit runs for 10 minutes consecutively in defrosting
mode.
3.5.5 Evaporator Coil Temperature Protection
• Off: Compressor stops.
• Decrease: Decrease the running frequency to the lower
level per 20 seconds.
• Hold: Keep the current frequency.
• Resume: No limitation for frequency.
3.6 Auto-mode
• This mode can be selected with the remote controller
and the temperature setting can be adjusted between
16°C~30°C.
Case 1:
• 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( 3.6 °F) Cooling
-3 ℃ ( -5.4 °F) ≤∆T≤2 °C( 3.6 °F) Fan-only
∆T<-3 °C( -5.4 °F) Heating*
Heating*: In auto mode, cooling only models run the fan
• Indoor fan will run at auto fan speed.
• 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 ∆ T.
Case 2:
In auto mode, the machine selects cooling, heating or fan-
only mode on the basis of T1,Ts and T4.
