        Comments about Three Position Actuator for Stations:

        I have used this actuator to control the temperature in the radiant floor of my church's parish hall. It functions perfectly with our Tekmar controller, and is very quiet. But, being an electromechanical device, it can't last forever. In 10 years, we've gone through two of these. The last one survived six years, because we wised up and shut the power off to it during non-heating months. This reduced the wear, since the floating actuator wasn't energized at all.
