2 point command: the command is made by a simple switch or button (manually or automatically operated e.g. traditional thermostat). Closing the control switch will cause the actuator to travel to the full CCW position. Opening the control switch will cause the actuator to travel to the full CW position. If the actuator is mounted on a ball valve, closing the control switch will open the ball valve, and viceversa.
Upon request, the command voltage may differ from the motor power voltage.
Note: if the limit switch signals are not to be used the yellow and pink wires must be capped to prevent accidental short circuits
3 point command: the command is made by a switch (manually or automatically operated e.g. 3 points thermostat), which diverts the voltage to the opening wire or to the closing wire reaching the actuator; the switch may be on open or on closed position; using a specific control, engine can stop in any intermediate position.
