The On/Off version the switch has three positions: Auto: In this position the actuator/valve is controlled by the way the assembly was installed. The heater is active. The hand wheel can be turned to move the valve but the valve will immediately move back to control signal position when the hand wheel is released. The power light is on. Off: In this position the actuator is without power. The heater is inactive. The hand wheel can be turned to move the valve to the desired position.

This position is used when the actuator is inactive for extended periods of time and to keep the condensation in the actuator low. The power light is off.
