NOTE: During temperature rise, medium speed changeover
has no requirement of forced running time . But during
temperature drop, the high speed must be forced to run
for 2 minutes before judging whether to directly turn to
the low speed.
• Auto fan action in heating mode:
3.5.3 Outdoor Fan Control:
Outdoor units just have one single fan speed. The
operation of outdoor fan is consistent with the operation
of compressor. Except the following situations:
• Evaporator high temperature protection
• Defrosting
• Current protection.
3.5.4 Defrosting mode
Case 1:
• The unit enters defrosting mode according to the
temperature difference between T2 and T1, as well as
the compressor runtime.
• 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:
• Compressor current is over than I
defrost
and lasts for
7s
• The defrosting time has reached the setting value.
• T2≥2°C(3.6°F) after entering defrosting mode for 3
minutes.
• After entering defrosting mode for 2 minutes,
check the value of T2. The minimum temperature
of T2 is marked as T2min. If T2-T2min≥2°C(3.6°F)
during the following 4 minutes, AC will exit
defrosting mode(if T2≤-15°C(5°F),considers it as
-15°C(5°F)).
Case 2:
• The unit enters defrosting mode according to the
value of temperature of T3 and the value range of
temperature change of T3 as well as the compressor
runtime..
• 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 TC2.
• Unit runs for 10 minutes consecutively in defrosting
mode.
3.5.5 Evaporator Temperature Protection
When the evaporator temperature exceeds a preset
protection value, the compressor ceases operation.
3.6 Auto-mode
• This mode can be selected with the remote controller
and the setting temperature can be changed between
17°C~30°C(62°F~86°F).
• In auto mode, the machine selects cooling, heating, or
fan-only mode on the basis of ∆T (∆T =T1-TS).
∆T Running mode
∆T>A Cooling
B≤∆T≤A Fan-only
∆T<B Heating*
Heating*: In auto mode, cooling only models run the fan
• Indoor fan will run at auto fan speed.
• The unit will choose running mode, when
• received the auto signal from the remote controller;
• forced-auto mode by pressing manual button;
