Set this parameter by using the DIP switch on the battery temperature
sensor. The address range is 16–28. Ensure that the address set on the LCD
is the same as that set for the DIP switch. Otherwise, communication fails.

sensors
An ambient temperature and humidity sensor has the same appearance as a
battery temperature sensor. The two types of sensors can be cascaded (up
to four). The ambient temperature and humidity sensor address range is
32–44, which is different from the battery temperature sensor. Therefore,
you can use the sensor as an ambient temperature and humidity sensor or
battery temperature sensor by setting the address.
NTC
The short-distance battery temperature sensor monitors the ambient
temperature near batteries, and ensures that batteries work reliably and
securely. The default status is Disable. If a short-distance battery
temperature sensor is configured, set NTC to Enable.
