8.2.5 Performance at Auto mode at Fan-only status is the same as that at Auto mode at cooling status,
provided that the set temperature is 24°c.
8.3 Cooling Mode Function Requirement
8.3.1 At cooling mode the 4 way valve is off.
8.3.2 Anti-icing Control for Indoor Evaporator
When the temperature of indoor heat exchanger drops to ≤ 4°c, the frequency will reduce one
step down (including F0) and last for 1 minute every time until the temperature is kept between 4
- 7°c. If the temperature rises to ≥ 7°c, the limitation then will be removed.
When the temperature of indoor heat exchanger drops to < 0°c, shut off the compressor and it
will resume when the temperature rises up to > 5°c.
8.3.3 Outdoor Unit Current Control When Cooling:
Note: The frequency down at the diagram is in accordance with the present frequency dropping
down, to determine every 2 seconds whether the frequency is keeping going down or is
recovering.
