Function:

1.Auto-fill-water modes connect the control’s blue line to electric pump, black line is connected to zero-line, brown line can not be connected and should be insulated.

2.Auto-drainage and lack-water protection modes connect the control’s brown line to electric pump, the black line is connected to the zero-line, the blue line can not be connected and should be insulated.

3.Fill-water and drainage auto-switch mode. The chart is fill-water and  drainage auto-switch mode. This electric connection chart synthesize by automatic fill-water and auto-drainage.
