Anyone know how they work? Looks like 3 wires. Common and one for moving the valve CW and CCW. I assume the limit switch just breaks the connection and that there is no feedback or position information?
I can't justify the large expense or time for hookup for a complete automation system. However, I did want to have remote push button capability to turn on the pump, heat and position the valves for either normal use or spa use (I've got a single pump for both). So would a 2 position rocker switch work, where one position sends 24v to one wire and the othe position sends 24v to the other wire?
Also, can you manually overide past limit switches? Say I have the limit switches set to trip at 0 and 90 degrees, can I then manually move the valve to 180?
