Description
Against cold air
The internal fan will be off to against cold air when the heat pump is heating.
De-frost cycle
The internal fan will be off to against cold air when the heat pump is heating.
Anti-protection of

The compressor will be off to protect internal battery when the product operates in Cool
mode.
Protect compressor
The product 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.
When the outdoor air suction temperature becomes lower than -10°C, the unit is changed to intermittent
operation to prevent freezing of the heat exchanger element and dew condensation within the unit.
