Yeah speaking of facts, the new Fleck SXT circuit board, used for all Fleck residential and small commercial control valves (ProFlo, TwinFlo, 2510, 2750, 2850, 7000, 5600, 9000, 9100 and 9500) looks like a clone of the Clack board! It has some of the features of the Clack boards but not all of the features of any Clack board (there is more than one) and the Clack is only 8 years old... There should be no reason to wonder why Fleck is copying some of the Clack features but knowing you, you might.
Maybe Fleck has a picture of the SXT on their web site, or.. I would trade ya one for a picture of your garage where your softener with the Clack valve used to be.
Now with Fleck copying Clack, it seems Fleck is the new kid on the block as you say!! And this isn't the first time, the 7000 was first in Feb 2005 and to be fair, it was done more to compete with a limited distribution Autotrol Performa valve than Clack valves. Now if I'm right, the SXT has dropped the feature that allowed it to compete with an Autotrol feature; it's not on the 7000/STX spec sheet. That feature and problems with the 7000 is why I stopped selling the 7000 in the spring of 2006.
Control valve circuit boards may look different than a board in a TV converter box, computer etc. etc. because control valve circuit boards are made to be used outdoors, indoors, in high or low humidity with very wide range temperature fluctuations and environmental conditions while TV converter box boards are not.
