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. 
A maximum of 12 BMUs can be cascaded.

Use the DIP switch on the BMU to set the BMU start address to 112. 
Ensure that the address set on the LCD is the same as that set for the DIP 
switch. Otherwise, communication cannot be implemented.

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. 
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.
