Input signal and function are chosen via the DIP-switch setting.
Function 1:
Single and double valve control. By double valve control, A valve is chosen by applying +Vsupply to terminal 2.
Function 2:
Double valve control with automatic change between A and B valves (no signal on terminal 2).
Input: 0...50% = A valve 100...0%.
Input: 50...100% = B valve 0...100%.
