Two different ways of WINVALL actuator control.
1. Single-wire control (also called On/Off control) uses one wire as the control wire. Once the control wire is energized, the valve opens electrically. If the control wire is unpowered, the valve closes.
2. Double-wire control (also called 3-Point control) uses two control wires. one for turning the ball counterclockwise , and one for turning the ball clockwise. Counterclockwise and clockwise turning let the valve open of close that depends on the installation way.
