The Battery Temperature Sensor is included with the charger to protect your battery and provide better

charging voltage accuracy.

When the battery temperature sensor is used, it is highly recommended to be installed on the main

battery bank at the negative terminal - Bank one.

The sensor senses the battery temperature and overrides the manual temperature settings and makes

small adjustments to the charging voltage.

When the battery sensor is not in use, you can also manually set the battery temperature. There are

three manual battery temperature settings on the unit (‘Lo’, ‘nor’ and ‘hi’).

Note: The above voltage compensation will only work with the supplied Battery Temperature Sensor tted which will

override the unit temperatures’ (Lo, Nor, Hi) setting. When Lithium prole is selected battery temperature is only used for

High and Low temperature shutdown. Refer to battery manuafacturer’s manual if temperature sensor is required.
