Circuit Board V3108 with 5 button controller used for Clack WS1 Valve and other "brands" that use the Clack 5 button straight across type of valve controller under their private label.
Note: Early models used a capacitor to "hold the time of day" and new models ( since about 2008 ) have used back up batteries.
The replacement board we ship includes these back up batteries on the circuit board, as shown in our primary product photo.
Also, the Newest version of the Board does NOT use the small circuit in "socket" J10 ( under the battery to left ) any longer ( and is not needed ).
Alternate photos shows the older version as installed on a Clack valve.The other photos are different / older versions of the WS1 control board. The separate circuit "module" at J10 location on the board is not longer necessary.
If you have the WS1 and your board looks like one of the older photos, then the new board would work as a replacement.
Please also NOTE: That there are a few "proprietary" versions of this controller that do not use the 3 or 5 button boards that we list and sell.
Those models use proprietary versions that have their buttons moved to unique locations, and therefore our standard 5 button control board would not match your cover / model.
That is not to say they would not "operate" the Valve, but the cover and buttons you have ( if different than shown ) could present a problem if purchased as a replacement.
When in doubt, please send us a photo via email for confirmation before ordering.
