Introduction to basic functions

Basic cooling functions

Air conditioner function:

To bring the ambient temperature to a comfortable level, the air conditioner absorbs heat from inside the room and discharges it outside.

Anti-freezing function:

If the unit is running in COOL mode and in low temperature, there will be frost formed on the heat exchanger, when indoor heat exchanger temperature decreased below 0°C, the indoor unit microcomputer will stop compressor running and protect the unit.

Basic heating functions

Heating function:

*Heat is generated from the outdoor unit is discharged inside to increase the temperature of the room. The heating effect will decrease in very cold outdoor conditions.

*If outside temperatures become very low, it may be necessary to use additional heating equipment.

Defrosting:

*When the unit is on for long periods of time and outside temperatures are low with high humidity, frost will form on the outdoor unit. The auto defrosting function will start, and the heat will stop for 8-10 minutes.

*During auto defrosting the fan motors will stop.

*During defrosting the indoor indicator light flashes and the outdoor unit will possibly give off some water vapor. This is not a malfunction.

*After defrosting is complete, heating will start automatically.

■ Introduction to basic functions

Anti-cool wind function:

To prevent cool wind from blowing in Heat mode, the indoor fan will not start if the indoor heat exchanger has not reached the correct temperature within 2 minutes. The anti-cool wind function operates in these conditions:

1.When Heating starts.

2.After Auto Defrost is complete.

3.When temperatures are low.

Gentle Breeze:

The indoor unit may blow a gentle breeze, and the guide louver rotate when:

1.When the unit is turned on in Heat mode and the compressor has not started.

2.In Heat mode, when the unit has not reached the correct temperature and the compressor is stopped.

*Working temperature range

	Indoor DB/WB (°C)	Outdoor DB/WB (°C)
Maximum cooling	32/23	52/31
Minimum cooling	21/15	18/ –
Maximum heating	27/ –	24/18
Minimum heating	20/ –	–7/–8

The operating temperature range (outdoor temperature) for the cooling unit is 21°C - 52°C; for the cooling and heating unit –7°C - 52°C.
