Low-voltage recovery: after the low-voltage protection

of the air conditioning battery, the low-voltage

protection will be automatically removed if the

battery voltage is above or equal to 25.5V; or starting

the vehicle to charge the battery making its voltage

higher than 25.5V to remove the low-voltage

protection.

In order to ensure the using time, it is

recommended to use the battery after it is fully

charged.

3. Remote control description

Power mode is used for fast cooling;

Eco mode is used when resting or reading is

preferred;

In Power mode, the default airflow is the biggest

with manual adjustment;

In Eco mode, compressor is running in low

frequency, airflow is defaulted as smallest with

manual adjustment.

Note: When ambient is above 35℃, and cabin in

high temperature, Power mode is preferable for

fast cooling with a result of biggest airflow and best

cooling effect.

Note: Strong recommendation for power mode

less than 20minutes. Long time operation will

significantly shorten the duration of use.

When cabin temperature is below 30℃, Auto

mode is preferred.

In different modes, users can adjust the air

volume according to their needs.

Please set it according to your own needs. Above

notes are only for reference.
