You can change between the two modes by holding down the A Button for 3 seconds.
Mode 1: Manually Scroll Through Display Information
Battery 1 Status Values
To toggle between Battery Voltage, Charging Current and Battery State of Charge (SOC) for Battery 1 and 2, press the B Button.
Push the B Button to show the voltage for Battery 1. Icons Displayed: Battery SOC, Volt Symbol (V), Symbol 1
Push the B Button to show the PV charging current for battery 1. The GP-PWM-30-UL will begin to limit the current as Battery 1 reaches a full charge. The current that is not used for Battery 1, is used to charge Battery 2. Icons Displayed: Arrow, Ampere Symbol (A), Battery SOC, Symbol 1

Mode 2: Automatically Change Display Information
You can select the auto mode by holding down the A Button for 3 seconds.
The display shows the same information as in Mode 1 but changes the display automatically every 8 seconds between following information:
Battery 1: Voltage; PV Charging Current; Battery State of Charge (SOC)
Battery 2: Voltage; PV Charging Current; Battery State of Charge (SOC)
If Battery 2 is not connected, the Controller changes only the information for Battery 1.
