2) Auto fan
For DC fan motor units:
• Rise curve
• When T1-Tsc is higher than -1.5°C, fan speed
reduces to 80%;
• When T1-Tsc is higher than 0°C, fan speed reduces
to 60%;
• When T1-Tsc is higher than 0.5°C, fan speed
reduces to 40%;
• When T1-Tsc is higher than 1°C, fan speed reduces
to 20%.
• Descent curve
• When T1-Tsc is lower than or equal to 0.5°C, fan
speed increases to 40%;
• When T1-Tsc is lower than or equal to 0°C, fan
speed increases to 60%;
• When T1-Tsc is lower than or equal to -1.5°C, fan
speed increases to 80%;
• When T1-Tsc is lower than or equal to -3°C, fan
speed increases to 100%.
For AC fan motor units:
3.4.3 Outdoor Fan Control:
• The outdoor unit will be run at different fan speed
according to T4 and compressor running frequency.
• For different outdoor units, the fan speeds are
different.
3.4.4 Defrosting mode
• The unit enters defrosting mode according to changes
in the temperature value of T3, 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 °C .
• T3 maintained above TCDE2°C 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.
For some models:
• If T3 is lower than 3°C and compressor running time
is more than 120 minutes, at this time, if T3 is lower
than TCDI1+4°C(39.2°F) for 3 minutes, the unit
enters defrosting mode. If any one of the following
conditions is satisfied, defrosting ends and the
machine switches to normal heating mode:
• T3 rises above TCDE1+4 °C .
• T3 maintained above TCDE2+4°C for 80 seconds.
• Unit runs for 15 minutes consecutively in defrosting
mode.
3.4.5 Evaporator 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.
3.5 Auto-mode
• This mode can be selected with the remote controller
and the setting temperature can be changed between
16°C~30°C
.
• In auto mode, the machine selects cooling, heating,
