5.4 Fan Mode
When fan mode is activated:
• The outdoor fan and compressor are stopped.
• 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.
•
Auto fan: In fan-only mode, AC operates the same as
auto fan in cooling mode with the temperature set at
24°C.
5.5 Cooling Mode
5.5.1 Compressor Control
∆
T
is the programmed parameter of temperature compen-
sation.
•
When
T1-Ts
<
∆
T-2°C,
the compressor ceases opera-
tion.
•
When
T1-Ts
>
∆
T+3°C,
the compressor continues
operation.
•
When the AC is operating in mute mode, the compressor
operates at a low frequency.
•
When the current exceeds the preset value, the current
protection function activates and the compressor ceases
operation.
5.5.2 Indoor Fan Control
•
In cooling mode, the indoor fan operates continuously.
The fan speed can be set to high, medium, low, or auto
.
•
If the compressor ceases operations when the con-
figured temperature is reached, the indoor fan motor
operates at the minimum or configured speed.
5.5.3 Outdoor Fan Control
•
For 264 and
354
models, the outdoor unit will be run at
different fan speed according to
T4
and compressor
operating frequency.
• For different outdoor units, the fan speeds are different.
5.5.4 Condenser Temperature Protection
When condenser temperature is more than setting value,
the compressor will stop.
5.5.5 Evaporator Temperature Protection
When evaporator temperature drops below a con-
figured value, the compressor and outdoor fan ceases
operations.
5.6 Heating Mode
5.6.1 Compressor Control
∆
T
is the programmed parameter of temperature compen-
sation.
• When T1-Ts >
-
∆
T, the compressor ceases operation.
•
When
T1-TS
< -
∆
T -4.5°C,
the compressor continues
operation.
•
When the AC is operating in mute mode, the compressor
operates at a low frequency.
•
When the current exceeds the preset value, the
current protection function activates and the compres-
sor ceases operation.
