This sensor measures the temperature at the battery and uses this data for 
very accurate temperature compensation. Accurate temperature 
compensation is important in ensuring proper battery charging regardless 
of the temperature.
The BT-1 Bluetooth module is a great addition to any Renogy charge 
controllers with a RS232 port and is used to pair charge controllers with the 
Renogy BT App. After pairing is done you can monitor your system and 
change parameters directly from you cell phone or tablet. No more 
wondering how your system is performing, now you can see performance 
in real time without the need of checking on the controller’s LCD. 
This PC communication cable is needed for remote monitoring using an 
optional PC software. Through the software, users could customize their 
charge parameters and other settings. Download the PC software through 
Renogy’s website under the “Downloads” section.
