All of the -SR and -MFT models (when programmed to 2-10 or 0-10 VDC) (with the exception of the SY, PR, and PKR Series) can be wired for On/Off or 2-position control by switching closed the #2 wire (24 VAC Hot) to the #3 wire (analog control signal input). The actuators half wave rectified circuit converts the 24VAC signal to 12 VDC which is an acceptable equivalent to a 10 VDC signal and the actuator will rotate open or closed depending on the position of the direction of rotation switch. Switching open the connection between wire #2 & #3 will cause the actuator to drive the opposite direction.
