And the anti-cold wind function has the priority.
• Anti-cold air function:
- The indoor fan is controlled by the indoor temperature T1 and indoor unit coil
temperature T2.

• When the indoor temperature T1 reaches the setting temperature, the compressor will stop,
the indoor fan motor runs at the minimum speed or setting speed. (The anti-cold air function
is valid).
• The indoor fan is controlled as below:

• Auto fan action in heating mode:
Outdoor Fan Control:
• 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.
Defrosting mode
• The unit enters defrosting mode according to the temperature value of T3 and T4 as well as
