The standardized temperature for heating is 7˚C. If the outdoor temperature drops to 0˚C or below, the heating capacity can be reduced depending on the temperature condition.

If the cooling operation is used at over 32˚C(indoor temperature), it does not cool at its full capacity.

Maintaining your air conditioner

internal battery

in Cool mode.

Protect compressor

The air conditioner does not start operating immediately to protect the compressor of the

outdoor unit after it has been started.

 

• If the heat pump is operating in Heat mode, De-ice cycle is actuated to remove frost from an outdoor unit that may

have deposited at low temperatures.

The internal fan is switched off automatically and restarted only after the de-ice cycle is completed.
