Circuit Board V3408EE-01 ( replaced by V3408EE-04 ) used for Clack WS2L Valve and sometimes Valves WS1, 1.25 or 1.5.
* Note: Newer Boards use 3 wire interconnect. If you have one bad Board, you'll need to replace Both Boards and get New Cable ( V3474 ).
The numbers should "match" and you should have only 4 buttons.
If you are not sure, then send us photos and model information before ordering.
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.
