LCD Screen
LCD Screen show the voltage of battery, charging current and current of loads in turn in every 5 seconds.

Thermoscope(Standard Accessory)
Installation：Plug the thermoscope into the socket (top) of controller before running of controller, and then connect battery with the controller. The thermoscope will normally work after one minute. (Operate as indicated in the fourth Chapter, the environmental temperature of controller will be available on LCD).
When controller starts up, controller will self-setup the Charging-off voltage, the Load-off voltage and the Load-on voltage according to the voltage of battery. These default parameters are setup as the standard environment temperature is 25℃.
